Introduction

In this assignment you will be asked to carry out the full software development life cycle.

You will:

• Analyse and design a distributed application using appropriate software analysis and

design tools;

• Develop the Distributed Application using the newest .NET technology. This

application that will be developed will not be restricted to any application type but it

should have distributed application techniques. In the following sections you will find

a list of tasks that you should perform to make sure that you build a correct

distributed application.

• Test your whole application and your COM+ component.

• Implement it and review it.

In the end,

Deadline is: Friday 4th June 2010 and no extensions will be given

as the weeks that

follows will be dedicated to interviews, correction and referrals. During the week starting 8th

June you will be asked to formally present your work to your tutors. Interview schedules

will be set and sent to you by your tutor in due course.

This assignment is linked with:

• Unit 10 (Software Development Project);

• Unit 35 (Distributed Design & Development);

Task 6: Exception Handling

Any exceptions that are encountered in the Data Layer must be bubbled up and handled in

the Business Logic Layer. When handling exceptions, you should capture specific exceptions

like instances of the class SQLException rather than generic exceptions like instances of the

class Exception.

You should also create custom exceptions that might be more specific to your business

rules. For example, a bank application might throw a BankAccountAlreadyExists

exception rather than a generic Exception object which might not provide sufficient

information to its caller.

BTEC 2HND 2010

Grading Criteria: VBE-P2.3 You should throw exceptions from your COM+ component when an error in the data layer is encountered.

You should also make use of encryption and decryption. If you are using any query strings these should always be encrypted and decrypted.

Grading Criteria: VBE-P3.3 The above security measures were applied and implemented in the application where applicable.

Task 8: Stored Procedures

Your COM+ component must make continuous use of stored procedures to access the data

layer. This will give you the maximum performance possible when accessing the data layer.

You will fail this criterion if you do not make use STORED PROCEDURES. All business logic

must be implemented using stored procedures. The COM+ component can then call the

stored procedure that will return back the required result. Underneath you can find a simple

example of a method that calls a stored procedure and that implements a particular

business for an application developed

Ex: Method called GetUnitsTaughtByLecturer(int lecturerId )

BTEC 2HND 2010

13

Stored Procedure called sp_GetUnitsTaughtByLecturer that returns the required

results for the method above.

Grading Criteria: VBE-P4.1, VBE-P4.2

tool. You can also make use of this tool to design some of your stored procedures. The

documentation should include

1. Introduction to design view tool in SQL Server

2. Step by step description of how this tool is used. You should at least provide one

step by step description of a view you have created.

3. You should also explain how you can use the VIEWS created to view the data in

Visual Studio

another type of presentation layer 3. AT LEAST 3 REASONS supporting your presentation layer

choice

Met Not Met

Task 11: COM+

The COM+ component that you will create in this task MUST PROVIDE ALL BUSINESS

LOGIC contained in your distributed application. You can also utilize stored procedures for

your business logic. However your COM+ component must be the interface between the

presentation layer and the data layer and therefore it is only the COM+ component that

must call the stored procedures created.

a) A distributed application is designed correctly if all business logic is written in an external

component. Components have been the focal point in distributed technologies for the past

ten years. They provide several benefits and one of the main benefits include reusability and

the advantage of being able to interact with any type of presentation layer. In this task you

should design and create a COM+ object that performs all the business logic for your

application. The main functionalities that the COM+ object will perform include

1. Accessing data in the data layer

2. Provide data to the presentation layer.

Grading Criteria: DDD-P4.1, VBE-P2.1, VBE-P2.2, VBE P2.6 Design and create AT LEAST ONE COM+ component that handles all business logic and then utilize this COM+ component in your application. Your COM+ component should address all client requirements that you have set in the proposal form. All your COM+ methods should be accessible through web services

You should divide your classes into different namespaces. Failure to do so will fail you in this outcome. Your COM+ component should include AT LEAST 4 different classes

Task 12: Data Integrity

In this task you should make sure that you have established correct relationships between

all your tables and that all data inserted in your table conform to the structure and rules you

have created. Your database should include

1. Test data in different tables

You should also make use of COM+ transactions to maintain SQL Server data integrity. You

should make use of these transactions when any business process is required to update

more than one table.

Task 13: Sql Server Security

In this task you should create user logins that will enable the users to connect to your

database. You should also make sure that correct permissions are set for all database

objects including stored procedures, tables and views.

You should prepare documentation that will describe what each login can access. Only users

having appropriate permissions should access database objects. Failure to include SQL

Server security will fail you in this criterion.

Examples of pair of tools (which you can compare) and perform the same thing are the following:

• The Strong Name Key tool – there is a tool which is integrated within Visual Studio that allows you to create a strong-name key file, and a command-line tool named sn.exe which does the same thing (in a different way)

• Caspol and .Net Framework Configuration Tool • Ildasm.exe and Object Browser within Visual Studio • Tlbimp.exe and the Add-Reference tool in Visual Studio (to create a runtime-callable

wrapper in Visual Studio for COM components)

Section G: Software Testing part 2

Task 1: Testing

Section G Task 1 consists of designing and performing the tests identified in Section F Task 1

Task 1.1 – Test Execution

Section 1: Manual Black Box Testing – Functional Tests

Test Case Design

For this section you need to download Test Log software from:

http://www.testlog.com/download.htm

To achieve the minimum number of test cases:

a. Select a web page from your project and identify the maximum number of test cases that should be done for exhaustive testing of that particular page.

b. Work out the minimum number of test cases that cover all tests using Combinatorial Testing

http://www.testlog.com/download.htm�

BTEC 2HND 2010

32

Using Test Log:

i. Create a new Project giving main information about the Testing Project (ex. Project Title, Test Manager and start and finish dates etc)

ii. Create 1 test case suite, for the minimum number of test cases in b)

iii. Document the test cases providing the following information:

a. Test Case Summary • Test Case ID • Test Case Name • Test Type

b. Test Case Description • Prerequisites and initial conditions • Test Instructions (what to test) • Expected Results

c. Test Case Execution Results • Actual Results • Status (Pass/Fail)

iv. Also create 1 test case suite for your COM+ object where you should test at least 5 methods from your COM+ object.

Section 2: Performance Tests

For this section you need to download Web Application Performance Tool (WAPT) from http://www.loadtestingtool.com/. Record the results of performance tests

a. Identify at least 3 Key Scenarios in your application (ex. Search for a product, Add

items to a shopping cart, place order, etc.)

b. Record browser actions as the scenario using Record/Playback tool of WAPT. Execute performance tests with the normal workload specified and increase load incrementally

c. For each scenario, observe and measure values of response time and resource usage (% CPU usage, % memory usage) for normal and increased workload. Document the results of performance tests.


Identify 3 Scenarios in your application Using WAPT, for each of the above scenario, record browser actions, increasing the workload incrementally For each scenario document the response times and other resources (statistics etc.) of performance tests
