1.5 LIMITATIONS OF THE STUDY The limitations of this project and project report are as follows:  •

The knowledge constraint of the project developer, especially regarding banking. Another main constraint of the study is time limitations many of the aspects could not be programmed and discussed in the present project and report such as General Ledger, Remittance sytem, Interest and Charges Calculation modules and Security and Encryption. In further increment this modules can be added in future.

Availability of data was limited. No original data set could be collected from banks due to their principle of customer information secrecy. Dummy data has been used.

As the literature reviews/documentation regarding banking software development was not very available. Different banking software developers don’t want to show their code to others.

1.6 THE PROJECT MANAGEMENT SPECTRUM Four P’s have a substantial influence on software project management—people, product, process, and project. People must be organized into effective teams, motivated to do high-quality software work, and coordinated to achieve effective communication. The product requirements must be communicated from customer to developer, partitioned (decomposed) into their constituent parts, and positioned for work by the software team. The followings are the 4 P’s of the project: 1.6. A PEOPLE One, the developer himself. To compensate the hunger of experienced analyst and developers needed in this kind of project, suggestions from banker/ex-bakers and experienced programmers are resolved. 1.6. B PRODUCT A Core Banking Software Solution can be called “Simple Bank”. The product objective has been defined as to deliver core banking service at a state of the art way promptly, efficiently and flawlessly. And scope of the project is defined by answering the following questions:


Context: How does the software to be built fit into a bank business context and what constraints are imposed as a result of the context? Information objectives: What customer-visible data objects are produced as output from the software? What data objects are required for input? Function and performance: What function does the software perform to transform input data into output? Are any special performance characteristics to be addressed? Additional questions also self analyzed are: • Who is behind the request for this work? • Who will use the solution? • What will be the economic benefit of a successful solution? • How would you (the customer) characterize "good" output that would be generated by a successful solution? • What problem(s) will this solution address? • Can you (Bank Officer) show me (or describe) the environment in which the solution will be used? • Will any special performance issues or constraints affect the way the solution is approached? The set of questions enables me to gain a better understanding of the problem and the customer to voice any perceptions about the solution. After scoping Problem decomposition or partitioning or problem elaboration has been done by me to elaborate the scope of the project. Each of these features represents a sub function to be implemented in software

1.6.c PROCESS Choosing the software engineering paradigm that is best for the project and the software engineering tasks was a difficult decision. A relatively small project that is similar to past efforts might be best accomplished using the linear sequential approach. But the project “Simple Bank” comprises not a small project. So the linear sequential approach is rejected. If very tight time constraints are imposed and the problem can be heavily compartmentalized, the RAD model is probably the right option. Here the project has to be accomplished at a very tight schedule but the human resource is not adequate to run a RAD model. So the RAD model is rejected. If the deadline is so tight that full functionality cannot reasonably be delivered, an incremental strategy might be best. In this project it is considered that the incremental process model will best serve the product development. The incremental model combines elements of the linear sequential model (applied repetitively) with the iterative philosophy of prototyping. The incremental model applies linear sequences in a staggered fashion as calendar time progresses. Each linear sequence produces a deliverable “increment” of the software. In this project, banking software developed using the incremental paradigm can deliver basic banking activities such as an account opening, cheque book maintenance, payment processing, summation of transactions and document production functions in the first increment; more sophisticated editing and report production capabilities in the second increment; parameterized system implementation in the third increment. The Interest and charges application module will be delivered in the fourth increment in future, and if necessary further addition will be made in further increment. The process flow for any increment can incorporate the


prototyping paradigm. When an incremental model is used, the first increment is often a core product. That is, basic requirements are addressed, but many supplementary features (some known, others unknown) remain undelivered. The core product is used by the customer (or undergoes detailed review). As a result of use and/or evaluation, a plan is developed for the next increment. The plan addresses the modification of the core product to better meet the needs of the customer and the delivery of additional features and functionality. This process is repeated following the delivery of each increment, until the complete product is produced. So, here the core product (mainly the transaction screen) is developed in first increment and after evaluation next additions such as account opening, cheque book maintenance, parameter, user activity in further increments.

Figure 1: The incremental process model used in this project The chief reason to select the incremental process model for this project is that it is iterative in nature. But unlike prototyping, the incremental model focuses on the delivery of an operational product with each increment. Early increments are stripped down versions of the final product, but they do provide capability that serves the user and also provide a platform for evaluation by the user. Incremental development is particularly useful for this project because staffing is unavailable for a complete implementation by the project deadline that has been established for the project. Early increments have been implemented by only one people- here the developer himself. 1.6.d PROJECT In order to manage successfully the software project, I have tried to understand what can go wrong by the following ways: 1. Start on the right foot. This is accomplished by my working hard (very hard) to understand the problem that is to be solved and then setting realistic objects and expectations 2. Maintain momentum. My emphasizing is on quality in every task the project/software performs. 3. Track progress. In this software project, progress is tracked as work products (e.g., specifications, source code, sets of test cases) are produced (using formal technical methods) as part of a quality assurance and easy scalability activity.


1.6.e PROJECT SCHEDULE This Software development project schedule was very hard to estimate accurately. But as an examination project my effort to develop the software was in 4(Four) months. No.

2.2 MEET WITH BANKERS: To gain an insight about banking and the manual system the first practical work was interviewing of bank professionals. I have gain knowledge about bank products, daily operations and different terms of banking from Mr. A. Qaium, Senior Officer, BRAC Bank Ltd. To know the problem of the manual system I have extensively interviewd Mr. K. M. Najmul Ahsan, Asstt. Operation Manager of Sonali Bank Ltd. Through them I have also interviewd several colleages of the said two. I have prepared questionnaires (Appendix 1-4) for the interview which helped me a lot to prepare the outline of the proposed software system. 2.3 ESTABLISH PRODUCT AND PROBLEM STATEMENT In-promptness in payment system, hard labor requiring in maintaining daybook and ledger, Inconvenience in maintaining precision in summation and balancing, Inability to give any kind of bank service one stop, manual working for interest calculation and charges deductions, Inability to get customer account statement on the go - are the most objectionable characteristics of manual bank system. On the contrary, in the proposed system a passing officer can get a customer signature card on the computer screen when he just enters the customer account number and if the cheque leaf presented in the counter for payment of that account holder is registered/entries in the system earlier against that account then the cheque can be easily recognizable as valid for payment provided that the balance of the account held sufficient for the transaction without any obligations. This dynamically reduces passing time of a cheque for payment in a bank counter than that of a manual system. In the new system account statement of a customer can be given instantly. I wanted to introduce a feasible system that faster and convenient. 2.4 DESIRED OUTPUT a. Transaction processing screen that can provide party account balance that can process credit transactions that can process debit by cheque transactions that can process debit by voucher transactions that can provide other operational status of a party b. Customer Account Statement c. Daily Transaction sheet/ Day Book d. Cheque Book statement/Register 2.5 SCOPE DETECTION


To determine scope I have answered the following questions: • How the software to be built does fit into a bank business context? The new system will take place of the manual day book, ledger, and registers and will assist the users/officers to take prompt action providing various information and constraints automatically. • What function does the software perform to transform input data into output? The software will permit the data to enter if it is a valid transaction and will store the transaction in physical database. The output of the data will be daybook, account statement, updated account balance etc. • Who is behind the request for this work? The customer of the bank will request a service such as payment of a cheque, or may request his account balance or may request for a cheque book to the Bank Officials. • Who will use the solution? Bank officials of different mid level position such as Asst. Officer, Jr. Officer, Officer, Senior/Executive Officer, and Senior Executive Officer The development environment scope is defined as followed: 

Report Engine: Crystal Report 2.6 DEFINE FUNCTION/BEHAVIOR/ PROCESSES Several functional areas in general banking are identified as: a. Account Open b. Cheque Book / Receipt Block Issue /Stop Payment c. Debit Party Account d. Credit Party Account e. Summation of Party Account Balance in Ledger f. Bank Statement Issue g. Change Party Account Status a. Account Open When a customer first come to a bank to transact on a relationship basis- the bank opens an account in the name of that customer and thus the banker-customer relationship builds. Commercial banks offer many deposit and advance products to their customers to choose and then open the customers account


on the selected/intended product ledger. Such as a man named A. Latif came to a bank to open an account in which he can transact by depositing and withdrawing from his balance. In this case his preferred product is Saving Deposit. The Bank will then provide him a savings bank account opening form which he will sign, fulfill and submit to the related bank official. The bank official will check the documents and then provide an account number particular to A. Latif. b. Cheque Book / Receipt Block Issue /Stop Payment After A. Latif’s account opens the savings bank account holder will deposit his money to the bank. When he intends to withdraw his money in future he will need a cheque book. So after opening an account the bank will provide a cheque book. The bank will provide cheque book to the account holder broadly to the products of the category 1 and category 2 Category 1. Time and Demand Deposit (Except Fixed Deposit) Category 2. Advances Category 3. Fixed Deposit Alike Product Account holder will get a Deposit Block Receipt instead of a cheque Category 4. Annuity Deposit account holders will not receive any cheque book. c. Debit Party Account When an account holder comes to withdraw money he will just place a cheque (which was issued to his account earlier) to the counter. The passing officer will verify the cheque and after his full consent and passing payment will be done to the account holder. In case of annuity deposit account holders (like SDPS, DPS) the money returned by Pay Order when an application of withdrawal from the account holder received. The fixed deposit account holder will just place his Fixed Deposit Receipt to withdraw the money. d. Credit Party Account When an account holder comes to deposit his money the cashier will take his money and will give back the customer part of the related voucher and the banks part will be retain for transaction. An officer will then make entry in scroll and ledger to update his balance. e. Summation of Party Account Balance in Ledger When a transaction is done the ledger balance of that account is also updated. For a credit transaction of Tk.500/- in A. Latif’s savings account an officer will just open the account related folio in the ledger and just put 500 on the credit side. Finally he will just add 500 with the balance in the previous row to get account current balance. f. Bank Statement Issue Sometimes a customer may ask for his transaction statement. An officer after receiving such request will then make a hand copy of the transactions in the ledger for that account on a prescribed format. g. Change Party Account Status


Party account status may be changed in different circumstances differently because, 1) A party may wish to close his account or 2) may gone deceased or 3) may have no transactions since 2/3 or more years or 4) may done fraudolous activities in his account. In several circumstances like these it is required that the account status is marked properly. In circumstance 1 the account status will be ‘Closed’, in 2 that will be ‘Deceased’, in 3 that will be ‘Dormant/ Inoperative’ and in circumstance 4 that will be ‘Restricted’. 2.7 COMMON PRODUCTS AND SERVICES IN COMMERCIAL BANKS A bank has wide range of product line to suit the need of the people of all strata. In addition to convention product a Bank offers special credit products for its customer. •

3.2 DATA MODELING Data modeling answers a set of specific questions that are relevant to any data processing application. To resolve the database structure I questioned myself the following questions: What are the primary data objects to be processed by the system? What is the composition of each data object and what attributes describe the object? Where do the objects currently reside? What are the relationships between each object and other objects? What are the relationships between the objects and the processes that transform them? In answering these questions, I have made use of the data dictionary and entity relationship diagram. The E-R-D enabled me to identify data objects and their relationships. On diagram 2 shown the relationship view of data objects based on the E-R-D. 3.2.a Data Dictionary Account Number Department Account Group Customer first name midname last name guardian mother name gender profession dob age id/passport village Post office Police Station District home phone office phone introducer opening Date expiry date ledger number Operation Mode Account Status Account of Caution savings current overdraft cash credit fixed deposit Table 2: Data Dictionary

To find an error to resolve black box testing method is used in the project. Black-box testing, also called behavioral testing, focuses on the functional requirements of the software. Through Black-box testing I have attempted to find errors in the following categories: (1) incorrect or missing functions, (2) interface errors, (3) errors in data structures or data base access, (4) behavior or performance errors, and (5) initialization and termination errors. By Black-box testing I have applied all possible sets of input conditions that will fully exercise all functional requirements for the program. By equivalence partitioning method the input domain of a program divided into classes of data from which test cases can be derived. In the test case single-handedly uncovers a class of errors e.g., incorrect processing of all character and numerical data. An equivalence class represents a set of valid or invalid states for input conditions. I have exercised every possible input the user can do in different controls. For example, an user may provide wrong account number or number with less or more digit, user may


enter cheque prefix with less characters or no character, user may enter character where only a numeric input is required, user may provide wrong transaction code, user may provide wrong cheque book starting leaf, user may provide wrong decimal amount such as an amount with three or more digit in the right of precision point etc.All the aforesaid input conditions are handled programmatically so that user may not be able to enter invalid data. Boundary value analysis is also done to several numerical controls. All the possible minimum and maximum values are exercised to find out error in the numerical controls such as account number textbox, amount text box, batch number text box, cheque number text box etc. in the transaction form. 6. DOCUMENTATION 1. Installation: Step 1: Run the setupreport.exe. It will install related files for the report engine. Step 2: Copy the Sbank.mdb database to C:\ drive of your system. Step 3: Copy simplebank.exe and paste a shortcut in desktop. Step 4: Step 4 is needed if the dotnet framework is not available in your system. Just run the dotnetfx.exe to setup dotnet framework 1.1. 2. Run Just double click the simplebank.exe and log in using valid id and password. 3.

CONCLUSION This report was an attempt to map out a document, which clearly explains the phases of banking application development, different application methods, data and function engineering processes with self description and documentation in a comprehensive way about the sample “Simple Bank� banking application software. Today it is widely recognized that availability of efficient information and transaction systems is essential for financial organizations like banks. So definitely there is good market for banking software and banking software developers. I am confident that I have acquired indepth knowledge about the practical orientation and experiences of dynamic software and business applications world after finishing this project.


8. RECOMMENDATION •

Back end or database can be upgraded to SQL server for greater data integrity, security and functionality.

To enable working in Network environment .net class and SQL features can be used in future.

Before launching the software in live mode the manual system and the automatic system should run parallel for 1 month so that any discrepancy in the new system can be detected.

The banking system should be operated by computer literate as well as ‘Simple.

Users should maintain their passwords secret.

Everyday backup of the banking database is strongly recommended.
