Introduction

The banking system in any economy , coupled with market relations should perform most , if not the most important role . First, the developed structure of commercial banks, operates a system of payments in the economically developed - market relations , the vast majority of commercial transactions performed by redistributing funds between retail bank deposits , by check or electronic transfer . Secondly , along with other financial intermediaries , banks direct savings in firms and enterprises .

One of the most important aspects of the structure of commercial bank operations is their automation . ATMs - ATMs dispensing and encash cash for operations with plastic cards. With ATM , you can also transfer money from one account to another , to get background information on the account, to conduct utility payment, payment due , etc. Thereby ATMs occupy an important role in bank processing .

ATM network - a very complex infrastructure, as she and many other equipment periodically fails. In turn ATMs require daily service to maintain uninterrupted service. For service ATMs, the bank needs to be serviced , which will support health , repair ATM network. But it would be difficult to imagine the work of such a department , without the support of the dispatch service . Dispatch service performs the function of collecting, processing of information , preparation of digital records . Product that will be developed in the course of the diploma project , designed to structure , organize work dispatcher.

Information system " accounting ATM network " will contain information on all the ATM network , as well include the ability to add , modify, delete information from the database , reporting , database search , ordering the list and the list of criteria and etc. This product will significantly accelerate the work department, streamline storage structure information across the ATM network . Staff of this department do not have to run various programs to store information , generate reports , to record the defective ATM , to find specific information , information system " accounting ATM network " includes all these features and more . This product is very important for bank processing and can be widely distributed among other banks , which in turn determines the importance of profitability and the need for this software .

1.7 Description of the design

Delphi Programming Language

Currently, programming is booming , both in terms of expanding their circle solved problems , and from the point of view of substantial complexity in programming technology. Moreover, it should be noted particularly sizeable software products developed . All this requires maximum simplify and accelerate the application development process and the use of previously implemented program fragments.

Such requirements for modern programming led to the creation of numerous RAD- systems , which are integrated development environments . They include:

- Fast and convenient means of constructing the programs , including the visual;

- Built-in compilers and debuggers ;

- A system of collective development projects, etc.

One of these systems is RAD Delphi. Delphi - an object- oriented environment for visual design Windows applications developed mechanisms to reuse code. The main competitor is the Delphi development environment Microsoft Visual C + +, which has its advantages and disadvantages, however, are more popular , mainly due to the fact that it was developed by Microsoft.

Delphi is an essential feature of a component model of software development . The essence of the model is to support a growing set of system object components that build program . Components in Delphi are easy to use and develop as a result of hiding a significant part of the structure of the program , which is close to the interaction with the operating system .

The most significant gap from Delphi closest peers is really rapid development of applications that have complex user interface , especially having a strong relationship between the controls located in the windows program.

Delphi also offers a pretty powerful set of components for working with databases . And hierarchy of components for database is organized in such a way that almost no matter what kind of database application uses - it can be a local database and a production server , such as Oracle or MS SQL Server. Delphi significant advantage in this area is the ability to manage databases at the logical level , the corresponding concepts databases themselves , without the use of low-level requests to the driver .

Such opportunities Delphi determined its wide applicability in the development of automated systems for business management . However, this is not the only area of application as opportunities are not limited to the above Delphi . Delphi is a general-purpose programming language and allows you to develop software of any complexity for any field. Even if some features and not directly supported , this drawback can be corrected by adding the respective components in the system. This approach applies, for example , technology DirectX, not supported by Delphi in its original configuration , but there are components for DirectX, which are easily integrated into the development environment .

In any case , the subroutine implemented in other Windows programming languages ??may be used in Delphi mechanism via dynamically linked libraries. Many Windows libraries initially connected to Delphi, and function calls are no different from conventional libraries Pascal.

In the Delphi language does not have the complex structures that are present , for example, in the language of C + +, Delphi but not inferior in their capabilities C + +. The speed of the programs created in Delphi is not less than the programs developed in the language C + +. The difference will be noticeable only when a large amount of mathematical calculations , due to an excellent ability to program optimization compiler C + +. However, the best optimization programs and takes more time , and this slows down the process of software development. Here , of course, the advantage of the compiler Delphi, which allows you to make changes almost instantly and check the result . Time is spent very little.

Delphi is also easy to learn , as well as Visual Basic, but the means of Delphi programming language allow you to use all the advanced features of object- oriented programming.

Delphi is simple and logical . The main language constructs are clearly distinguished in the program that promotes good perception of the written code , unlike language Visual Basic, where the code is almost impossible to understand , if it exceeds a couple of pages . Delphi GUI well thought out , and the development environment provides access only to those portions of the code , you want to work , hiding the main part of the program , which is created automatically by the development environment .

With the advent of the development environment Kylih for the operating system Linux, Delphi is fully compliant with the exception of some aspects related to the differences in the technologies used in these operating systems , some applications written in Delphi, became tolerated under Linux, which opens up even more opportunities this environment development .

Language with SQL databases

SQL ( usually uttered as a " sequel " ) symbolizes the Structured Query Language . This - the language that gives you the ability to create and work with relational databases , which are sets of related information stored in tables.

Database world is becoming more and more common , resulting in the need for a standard language , which could be used to operate in a large number of different types of computing environments . Standard language allows users who are familiar with one set of commands , use them to create, retrieve , modify, and transmit information , regardless of whether they work on a personal computer , a network workstation , or mainframe .

In our increasingly interconnected computer world , equipped with a user in a language has a huge advantage in the use and synthesis of information from a variety of sources with a large number of ways.

Elegance and independence on the specifics of computer technology, as well as its support for industry leaders in the field of relational database technology has made SQL, and probably for the foreseeable future leave him , the main standard language . For this reason , anyone who wants to work with databases 90s should know SQL.

SQL standard defined ANSI ( American National Standards Institute ) and is now well accepted by ISO (International Organization for Standardization ) . However , most commercial database applications without notice expand SQL ANSI, adding various other features in the language, which they believe will be very useful .

Sometimes they violate some standard language, although good ideas tend to develop standards and will soon become the "market" themselves by virtue of their utility qualities.

SQL language is non-procedural language of the database. In this case it means that the user can only execute each command separately and can not be set and two more operators in the command line .

DBMS Microsoft Access.

Microsoft Access is a relational database type, which is reasonably balanced all the tools and features that are typical for modern DBMS . Relational database simplifies the search , analysis, support and protection of data as they are stored in one place. MS Access - it is functionally complete relational DBMS . Besides , MS Access is one of the most powerful , flexible and easy -to-use database . It is possible to create most applications without writing a single line of code , but if you want to create something very complex .

Microsoft Access database popularity due to the following reasons:

- Accessibility and clarity in the study allow Access is one of the best systems for the rapid creation of database management applications ;

- The possibility of using OLE technology;

- Integration with the package Microsoft Office;

- Full support for Web-based technologies ;

- Visual technology allows constantly see the results of their actions and correct them ;

- The presence of a large set of "masters" for the development of facilities.

2. Definition of requirements

This section describes the basic diploma project functional and nonfunctional requirements , and discusses the analysis methods, techniques , algorithms development, requirements for the implementation of database queries and treatments that occur during system operation.

2.1 Functional requirements

Organization requirements precedents

Behavior of the system , that is a representation of a user is represented as a precedent. Case model can be developed at different levels of abstraction. During the analysis phase precedents absorb requirements , focusing on what makes or the system should do .

Precedent performs the business function that can monitor the external entity . Subject ( actor) - is someone or something that interacts with the precedent , waiting to eventually get a useful result .

Use case modeling is closely associated with the establishment of requirements. Requirements set out in tabular format in the document describing the requirements necessary to bring to the precedents , but this only applies to the functional requirements . If during the development lifecycle user requirements change , these changes should be reflected in the document describing the requirements , and the use case model .

Each use case shall be described with the help of the event flow documented . Corresponding text document specifies that the system should do when an actor initiates precedent.

Application Module

Application module applies to the entire configuration as a whole is responsible for the user's session ( session) with the application . This module describes the global variables , as well as processing and functions that are triggered when the system starts and before shutting down the system. To work correctly, the configuration requires that the information base , even before the user configuration has already been wound up certain mandatory information :

a) were filled with specific values ??of some constants ;

b) Reference introduced mandatory elements .

Also provides an initial seed directories necessary information - to accelerate the start of the user configuration . This is done through a call processing " initialization ". The configuration should be able to determine when it is run for the first time and perform the necessary actions . In this mandatory initial seeding is done without any additional requests from the user , and optionally - with the preliminary inquiry . Outlined requirements implemented using a universal mechanism populate and update the IB .

Application module is responsible for creating the title of the main application window and determine the parameters of the session.

Module "Search"

Module "Search" is designed to build a user search query , to retrieve data on a given query , to display the data obtained after the search for the formation of the reporting forms on the found data. The initial data for this function module data is directly related to the ATM. The result of this function module will be found data on user's search query as a reporting form for the print output .

The main functions of the module "Search" :

a) selecting from the list of ATM ;

b) selection criteria for the search ;

c) found in search fields ;

d) The results obtained on request ;

d ) generating an output in a report form ;

e) forming and viewing the output forms in paper form .

Module " adding, changing or deleting data "

Module " Additions, changes , delete data " is intended to change the values ??in the database fields such as name , phone number , region, ATM model . This module is organized accounting system data , data control system . The initial data for this function module data is directly related to the ATM.

Module " Formation dresses "

This module is designed for people belonging to the group component of the repair machine. This group monitors the status of all people ATM performance. Just around the clock monitoring of the entire network , in parallel synchronizing data with real data in a database that allows you to contribute more effectively to the service department . Generating unit orders , you can view the generated outfits , closed open outfits. Once the outfit is created, it is automatically added to the database.

Module " Closed dresses "

This module is designed for the people belonging to the group of engineers engaged in service ATM network. This module allows users to a group of engineers , closing attire. At the entrance to the form of this module , the application automatically displays a list of orders drawn up by the user. Engineer is able to view all applications compiled on it ( outfits ) , open, closed . After viewing attire engineer carries ATM service , which was formed by the application , and then fills the outfit previously formed on it, and carries its closure attire. After closing attire data is automatically entered into the database that stores the complete history of the entire ATM network.

Module "Administrator"

Module "Administrator" is intended for distribution rights of users to the system and the database, configure the basic modules "adding , modifying, deleting data ," " Formation of dresses ," " closed, together ." The initial data for this function module is the information about the system users and their system requirements . The result of this function module will be configured by the administrator modules according to the requirements for each group and the distribution of rights for each user.

The main functions of the module "Administrator" :

a) setting limits access to individual modules ;

b) account administration ;

c) transfer account to another group;

d) establishment of access rights for each group ;

d ) maintenance manuals : adding data to the directory Adjustments directory data , deleting data from the directory.

2.2 Non-functional requirements

Subsystem must without fail to respond to any user action. Subsystem must operate efficiently when multiple client nodes . Subsystem must provide synchronization between client computers and server computers.

Error Handling

If incorrect user actions , or if you can not make some operation at the moment , the subsystem must issue a message that will indicate what must be done to implement the selected action or to continue.

All errors in the subsystem must be presented in a suitable form for the user . Necessary to implement the subsystem alert invalid user actions , such as entering incorrect information.

Restrictions

As DBMS use MS Access.

Inverse requirements

System does not guarantee a small query processing time when network problems .

In this subsystem can not accommodate transmission of electronic documents over the Internet.

3. Special Part 3

3.1 The domain model

Under the modeling domain refers to one of the initial stages of system design , which is necessary for the identification, classification and formalization of information about all aspects of the subject area , determining the properties of the system. Subject area of the developed system is the account of the ATM network , improving the efficiency of monitoring between departments and service.

3.2 Specification precedents

UML- standard specification precedent exists. However, widely used template below .

In this simple pattern specification includes the following information :

Name precedent. There is no standard for naming precedents . Precedents describe the behavior of the system , so the name of precedent must always be a verb or a verb group;

- A brief description - paragraph, which sets out the purpose of precedent ;

Actors are involved in the precedent . Top - actors initiating precedent and minor - actors interacting with precedent after initiation ;

- Preconditions - conditions that must be met to precedent could be realized ; that restrictions on the state of the system . Otherwise, the preconditions are called constraints ;

- Main stream - the steps involved in precedent. Describes the "ideal" course of events in a use case ;

- Postcondition - conditions that must be met at the end of a precedent ;

- Alternate streams - a list of alternative main stream of events.

3.3 Use Case diagram

Case diagrams are used for modeling the kind of system in terms of precedent (or use cases ) , ie the system architecture . Most often this involves modeling the context of the system, subsystem , or class or modeling requirements for the behavior of these elements .

Case diagrams are important for visualization of specifying , documenting and planning element behavior . They facilitate the understanding of systems, subsystems or classes , introducing outside view on how the data elements can be used in the appropriate context . Also, important to this chart of executable test systems direct process for the understanding and design of the internal design of the device in reverse .

This section lists and describes the following basic specifications precedents:

a) screening operation;

b) administration session .

Use case diagram " session with the system " is presented in Figure 1.

3.4 Sequence Diagram

The sequence diagram describes the interactions between objects instance , placing them in chronological order ; it shows the "life line " of the objects involved in the interaction and the messages they send to each other .

The sequence diagram graphically depicts the details of interaction of business workers and business entities and how to appeal to business entities in the course of a business use case. The sequence diagram briefly describes what they are doing business workers involved as managed business entity , and how they communicate by sending messages to each other .

Use case diagram for posing the problem is shown in Figure 2 .

3.5 Database Design

Data model, that is a conceptual description of the subject area - the most abstract level of the database design. The main model is the definition of domain model type entity / relationship (ER- method). This model defines the semantic description of the subject area and to provide information to determine the basic data structures. Elements describing the model are entities, attributes and relationships.

Essence - it's something about what you need to store information in the system being developed. Most entity objects or events simulate real-world examples can serve customers, products, etc. this specific entity. Essence can also simulate and abstract concepts. The most striking example - the essence of modeling the relationships between the entities: for example, the fact that a commercial agent is responsible for a specific customer.

In the developed system will store the parameters of each of the entities. These are called the attributes of an entit. Defining the attributes that should be included in developing a model - a semantic process. Solving this problem, you need to be based on the fact that the stored data really mean, and how they are used.

Addition to the attributes of each entity data model should define the relationships between entities. At a conceptual level communication are simple associations between entities.

It outlines the main entities:

- Number of ATM ;

- Name ;

- Address ;

- Model of ATM ;

- The state of the machine.

The logical data model describes the facts and objects to be recorded in the future database. The main components of the model are essentially their attributes and relationships between them. Typically, the physical nature of the analogue in the future is a database table, and physical analogue attribute - the field of the table.

From a logical point of view, the essence is a collection of similar objects or facts known instances of this entity. Physical analogue instance is usually record in a database table. How to write a table in a relational DBMS instances of the entity must be unique, a complete set of values ??of their attributes should not be duplicated. And in the same way as the field in the table attributes may be key and non-key.

The logical model is shown in Figure 4.

Figure 5 . Window user authorization

For subsequent run the main application window should:

a) choose from the list the name of the user;

b) enter the appropriate password to the user .

After login in the system's main window will be as shown in Figure 6.

Below are the main features of the user in the system:

a) work with the database through ATMs ;

b) formation of outfits;

c) generation of reports;

d) adding, changing, deleting objects;

d) search for items and objects in the system .

Figure 7 shows the window for a new outfit for the engineer.

When forming an engineer outfit, named parameters operator applicant for repair, the name on which the engineer was filed, the date of formation of the new outfit is automatically added to the database outfits.

Automatic addition of base outfits shown in Figure 8.

4. The economic part

4.1 Purpose and Objectives

he main objective of the proposed thesis is to create an information system automated account updating information on ATMs , creating outfits for engineers.

An analysis of the input data, the program gives the user the final reports on the status of the ATM at a given time , the fault ATM information on applications for repairing the machine.

The main objective of this project is to reduce the costs spent on maintenance personnel performing work on notification service service , filing . Just reducing the time when generating the report on the ATM about his condition . In consequence of that should be observed to improve the quality and standards of efficiency ATMs.

4.2 Calculation of economic efficiency of the accounting information system network of ATMs.

Effectiveness of the software system is characterized by indicators that reflect the cost-benefit ratio. Value to the findings of economic efficiency of PS depends, first, on the completeness and accuracy of input data and, secondly, on the correctness of the methods used in their processing and analysis.

Calculation of the cost of development and implementation of a software module

Costs to develop and implement a software module is calculated as follows 1:

C = STZ + + Salga Sotla + IOS + SBC + Art (1)	(1)
where STZ - development costs of technical specifications; Salga - algorithm development costs; Sotla - the cost of writing and debugging programs; SVN - the cost of implementing the program; SBC - acquisition costs of the technical means; Art - the cost of testing the software.

Calculation of the cost of development of technical specifications

For developing technical specifications was drawn developer, with hourly wages. Costs of developing technical specifications defined by the formula 2:

STZ ZPrazrab * = B + Otzp,	(2)
where ZPrazrab - cost of services developer = 500, t / h; - Time spent on the development of the algorithm = 3 days with 8-hour workday; Otzp - deductions from wages for social services (11%).

Total to develop the terms of reference were produced software module costs in the amount of:

Salga = 500 * 24 + 1320 = 13320 (KZT).

Calculation of the costs of developing the algorithm

For algorithm development software module was attracted specialist developer, with hourly wages.

Development costs of the algorithm are calculated using Equation 3:

Salga ZPrazrab * = B + Otzp,	(3)
where ZPrazrab - cost of services developer = 500, t / h; - Time spent on the development of the algorithm = 5 days, 8-hour workday; Otzp - deductions from wages for social services (11%)

Otzp = 20000 * 0.11 = 2200 (KZT).

Total to develop the algorithm software module costs were made in the amount of:

Salga = 500 * 40 + 2200 = 22200 (KZT).

Calculation of the cost of acquisition of the technical means

In paragraph 4.2 of this chapter lists recommended hardware with minimal characteristics ( RAM , software , etc.) , but to ensure the efficient and stable operation of the software modules required hardware with the following parameters :

Intel Pentium - 3.0 GHz / ;

The amount of RAM 512 MB ;

Hard disk capacity of 80 GB ;

128 MB video card ;

CD-ROM;

Monitor Samsung - 17 ' ;

The acquisition cost of a computer with such characteristics will be 63,500 kzt, the cost of the printer HP 1200 is 20,000 kzt. Total purchase amount SBC PC = 83500 kzt.

Calculating the cost of writing and debugging program

Costs are determined by the formula 4:

Sotla = Spevmotl + FZPotl,	(4)
where Spevmotl - cost of writing and debugging programs using a PC; FZPotl - payroll specialist in writing and debugging programs;

Cost of the work of writing and debugging programs using PC was calculated by the formula 5:

Spevmotl Votl * = * totl qotl,	(5)
where Votl - time spent writing and debugging program = 69 days; totl - while working on a PC in the day = 6 hours; qotl - an hour of computer time, the cost of specialist works on the PC.

Hour of computer time is determined by the formula:

q = S / T * 0.8,

where S - the annual cost of using computers (tenge);

T - number of hours of computer use per year, hour.

Annual costs of the use of computers, defined by the formula 6:

S = U_рем + U_ам + U_з/п + U_элек, (6)

where U_рем - costs for equipment repair, Tenge (taken at the rate of 10% per annum of the cost of the equipment);

U_ам - depreciation expense tenge (deducted from the calculation of 25% per annum of the cost of the equipment);

Uz / p - wages programmer tenge (including social contributions by 11%);

Uelec - energy cost (tenge);

Urem = 83500 * 10% = 8350 (KZT);

Uam = 83500 * 25% = 20875 (tenge);

Uz / p = 4000 * 69 + (4000 * 69) * 11% = 30360 + 276000 = 306360 Energy cost is calculated based on the power consumption of the computer and the cost of a kilowatt. Electricity consumption per hour is 0.4 kWh, the cost of 1 kW / h is 10.59 m. Given that the number of hours to use the PC is 414 hours (23 days per month and 6 hours of work on the PC per day), the cost of electricity consumed will be:

Uelek = 0.4 * 414 * 10.59 = 1753.704 (KZT).

Annual costs of computers are:

S = 8350 + 20875 + 306360 + 1753.704 = 337338.704 (KZT).

Based on the fact that while working on the PC per day is 6 hours, and 23 working days per month, the number of hours of computer use per month is equal to 138 hours. Then the number of hours of computer use per year is equal to 1656 hours.

The cost of one hour of computer time will be:

q = 337338,704 / 1656 * 0.8 = 163 (t / h).

Cpevmotl = 69 * 6 * 163 = 67482 (KZT).

Payroll will be:

FZPotl * 69 = 4000 + 30360 = 306360 (KZT).

Total costs for writing and debugging software module are as follows:

Sotla = 306360 + 67482 = 373842 (KZT).

Calculation of the costs associated with the implementation of the program

The costs of implementing the program are determined by the formula 8:

SVN = Cpevmvn + POFvn,	(8)
where Cpevmvn - cost of using PCs during implementation; POF ext - payroll programmer during the implementation;

Стоимость работ с использованием ПЭВМ за время внедрения определяется по формуле 9:

Спэвмвн = Ввн * tвн * qвн,	(9)
where BBH - time to implement the program = 23 days; tvn - while working on PC = 5:00; qvn - cost of a specialist on the PC = 163 (t / h);

Cpevmvn = 23 * 5 * 163 = 18745 (KZT).

Payroll is determined by the formula 10:

POF ext = ZPrazrab * BBH + Otzp,	(10)
where ZPrazrab - wages programmer implements = 17000 (m / month); BBH - time to implement the program = 1 month; Otzp - deductions from wages for social services (11%).

Payroll system implementation is:

POF ext = 17000 * 1 + 1870 = 18870 (KZT).

System implementation costs were made in the amount of:

SVN = 18745 + 18870 = 37615 (KZT).

Calculating the cost of software testing

Costs are determined by the formula 11:

Cm = Rm + FZ / p t, (11)

where Rm - the cost of computer time spent on testing programs (tenge);

FZ / p t - Programmer salary fund for testing programs (tenge);

where ZPrazrab - wages programmer performing testing = 2500 (tons / day);

BBH - time testing program = 10 days;

Otzp - deductions from wages for social services (11%)

FZ / p t = 10 * 2500 + (10 * 2500) * 11% = 27750 (tenge);

Km = 10 * 8 * 163 = 13040 (tenge);

Article = 13040 + 27750 = 40790 (KZT).

The total cost of the development and implementation of software

Development costs and implementation of software made??, determined by the formula 12:

C = STZ + + Salga Sotla + IOS + SBC + Cm (12)

C = 13320 + 22200 + 83500 + 373842 + 37615 + 40790 = 571267 (KZT).

Calculation of costs to implement a program

Monitoring work status, performance, fault ATM networks operate three managers.

The costs of fixing the problem without the use of the accounting information system of ATM network is calculated as follows 13:

FZPi = ZPigod + Otzp,	(13)
where ZPigod - salary in year 3 managers; Otzp - deductions from wages for social services (11%).

Annual salary of 3 managers to implementation of the program module is determined by the formula 14:

ZPigod = PAZ * N * 12,	(14)
where PAZ - wages 1st = 30000 Manager (m / month); N - the number of people involved in the design = 3 people.

Wages 3 managers in the design department of the year was:

ZPigod = 30000 * 3 * 12 = 1080000 (KZT).

Labor costs two managers without automation were:

FZPi = 1080000 + 118800 = 1198800 (KZT).

Costing after the introduction of software

After the introduction of a software module to the work of accounting, monitoring and fault, making applications for engineers need one person.

Annual salary engineer, using software module will be determined by the formula 15:

ЗПигод = ЗПи * 12 * N + Отзп,	(15)

To calculate the annual salary of the operator based on the following data: RFI = 30000 tenge, N = 1 person.

Otzp = 30000 * 0.11 = 3300 (KZT).

Annual salary of an engineer was:

ZPigod = 30000 * 12 + 3300 = 363300 (KZT).

The annual cost of printing the results of a software module for the printer is defined by 16:

Спеч = tпеч * Nвар * q,	(16)
where tпеч - time to print one copy = 0.07 min = 0.0012 h; Nвap - number of copies = 10000 (copies / year); q - cost of one hour of computer time = 163 (t / h).

Printing costs amounted:

С_печ = 0,0012 * 10000 * 163 = 1956 (KZT).

Total costs after the introduction of the software module are defined by 17:

Ссум = Спеч + ЗПигод,	(17)

С_сум = 363300 + 1956 = 365256 (KZT).

Calculation of saving money

Calculation of cost savings after the introduction and use of the module is defined by the formula 18:

Э = Здо - Зпосле,	(18)
where Здо- costs to the implementation of information systems; Зпосле- costs after the introduction of the information system.

Saving money after the introduction of this software is:

Э = 1198800 - 365256 = 833544 (KZT).
