Background and Project Specifications:

Most of the Banks are using online Computer based System for

their operations. Assume that you are asked by a new Bank to

design and implement a web-based system for basic bankingoperations like opening an account, withdrawal of money through

cash or cheque only, deposition of money, money transfer from

one account to another and calculation of account interests for two

different kind of customers customers having savings account

and customers having fixed deposit amount. An account should

have a minimum balance and rate of interest. A person holding the

savings account can only perform 50 transactions in a month. The

bank also needs to implement the process of closure of an account.

You may study such manual system at any Bank. Perform the

following tasks for the Bank.

Question 1: (10 Marks)

Which Systems Development Life Cycle (SDLC) will you

propose for the specification given above? Justify you selection by

evaluating suitability of at least two SDLCs. Solution:

SOFTWARE DEVELOPMENT LIFECYCLE

From the inception of a given idea for software system, until it is

implemented and delivered to the customer and even after that the

system undergoes the several changes. The software is said to have

a lifecycle known as Software Lifecycle composed of several

phases. Each of these phases results in the development of either a

part of the system or something associated with the system, such asa test plan or user manual. In the traditional and most commonlifecycle model called WATERFALL MODEL, each phase has

well defined starting and ending points with clearly identifiable

inputs to the very next phase attached to it. It is actually the first

engineering approach of software development.

Below Figure depicts the Water Fall Model.

The waterfall model provides a systematic and sequential approach

to software development and is better than the build and fixes

approach. But, in this model, complete requirements should be

available at the time of commencement of the project, but in actualpractice, the requirements keep on originating during different

phases. The waterfall model can accommodate new requirements

only in the maintenance phase. Moreover, it does not incorporate

any kind of risk assessment. In the waterfall model, a working

model of software is not available. Thus, there is no way of

judging the problems of the software in- between different

phases.A slight modification of the waterfall model is a model withfeedback. Once software is developed and is operational, then thefeedback to various phases may be provided.

goingto be the benefits in terms of finance? Perform a cost-benefitanalysis for the proposed software. List the major tasks andmilestones of the Project and make a project schedule. You

schedule must include both GANTT and PERT charts. Explain the

two charts drawn by you.

Time Feasibility:System Will Prepare in 6 Months &1 Month for the Training a

Staff.

Cost-Benefit Analysis: Cost of Human Resources System Analysts = 1 * 15000 =15000 Software Engineers = 2 *10000 = 20,000 Programmer = 2*10000 = 20,000 Cost of infrastructure Total Computer System Required = 3 * 35 000 = 1,05,000

Cost of trainingTraining StaffMember = 12 * 1000 =12,000

Question 3: (10+15 Marks)

Study the system and create a software requirement specification.

You must identify either the processes or objects while analyzing.During theanalysis give consideration to possible input and outputof the processes. After identifying the requirements, createAnalysis Models. You may either usethe classical approach anddraw Entity relationship model and data flow diagrams (DFDs) upto level 2-3; or you may take object oriented analysis approach andcreate class diagram, use case diagram, use cases, etc.

The Testing Spectrum

Testing is involved in every stage of software life cycle, but the

testing done at each level of software development is different in

nature and has different objectives.

Unit Testingis done at the lowest level. It tests the basic unit ofsoftware, which is the smallest testable piece of software, and is

often called "unit", "module", or "component" interchangeably.

Integration Testingis performed when two or more tested unitsare combined into a larger structure. The test is often done on both

the interfaces between the components and the larger structurebeing constructed, if its quality property cannot be assessed fromits components. System Testing tends to affirm the end-to-end quality of theentire system. System test is often based on the

functional/requirement specification of the system. Non-

functional quality attributes, such as reliability, security, andmaintainability, are also checked.

Acceptance Testing is done when the completed system ishanded over from the developers to the customers or users. The

purpose of acceptance testing is rather to give confidencethat the

system is working than to find errors.

Static Analysis and Dynamic Analysis

Based on whether the actual execution of software under

evaluation is needed or not, there are two major categories of

quality assurance activities: Static Analysis focuses on the rangeof methods that are used to determine or estimate software quality

without reference to actual executions. Techniques in this area

include code inspection, program analysis, symbolic analysis, and

model checking.


15/16

Dynamic Analysisdeals with specific methods for ascertainingand/or approximating software quality through actual executions,

i.e., with real data and under real circumstances. Techniques in this

area include synthesis of inputs, the use of structurally dictated

testing procedures, and the automation of testing environmentgeneration. Generally the static and dynamic methods are

sometimes inseparable, but can almost always discussed

separately. In this paper, we mean dynamic analysis when we say

testing, since most of the testing activities execution of the

software.

Functional Technique and Structural Technique

The information flow of testing is shown in Figure 1. As we cansee, testing involves the configuration of proper inputs, execution

of the software over the input, and the analysis of the output. The

"Software Configuration" includes requirements specification,

design specification, source code, and so on. The "Test

Configuration" includes test cases, test plan and procedures, and

testing tools.

Based on the testing information flow, a testing techniquespecifies the strategy used in testing to select input test cases andanalyze test results. Different techniques reveal different quality

aspects of a software system, and there are two major categories of

testing techniques, functional and structural.

Functional Testing: the software program or system under testis viewed as a "black box". The selection of test cases for

functional testing is based on the requirement or design

specification of the software entity under test. Examples ofexpected results, some times are called test oracles, include

requirement/design specifications, hand calculated values, and

simulated results. Functional testing emphasizes on the external

behavior of the software entity.


16/16

Structural Testing: the software entity is viewed as a "whitebox". The selection of test cases is based on the implementation of

the software entity. The goal of selecting such test cases is to cause

the execution of specific spots in the software entity, such as

specific statements, program branches or paths. The expected

results are evaluated on a set of coverage criteria. Examples of

coverage criteria include path coverage, branch coverage, and data-

flow coverage. Structural testing emphasizes on the internal

structure of the software entity.
