Description

The company has asked you to build a prototype of an n-tier system using the Northwind database as an example. The company wants to be able to add, edit, and delete records from the customers, orders, order details, products, categories, and suppliers tables. Your instructor will provide you the online link to the SQL Server database files (MDF and LDF).

  • Create the Data Access tier and Data tier projects:
    1. Create a class library project for the Data tier.
    2. Add a new class library project the project created in Step 1 for the data access tier.
    3. Add a typed DataSet using a new data source that connects to the Northwind sample database.
    4. Select the database objects (customers, orders, order details, products, categories, and suppliers) tables.
    5. Make sure the TableAdapters are stored in the Data Access tier and the DataSet class is added to the Data tier.
  • Make sure that separate tiers are created for each layer by verifying that separate class libraries were created and the necessary references to the project were added.

Using the project you started, verify the business logic layer (middle tier) is working correctly and make the connection to the database, implementing the logic in the data layer provided to manipulate the data stored in the database portion of the n-tier system.

  • Add the following to the project:
    1. Add a new Windows Communication Foundation (WCF) service library project to the Phase 2 individual project to communicate with the Data Access tier.
    2. Add the necessary queries and methods to the table adapters that will return, add, edit, and delete the data from the tables specified in Phase 2.
    3. Add references in the Data Service to the Data tier and Data Access tier projects.
    4. Add methods to the Data Service class created in Step 1 that will call into the Data Access tier.
  • Make sure that separate tiers are created for each layer by verifying that separate class libraries were created and the necessary references to the project were added.

Using the project you worked on in the Phase 2 of the project, finalize the design and functionality of the graphical user interface (presentation tier) and business and data access layers to prepare the Windows form application for deployment to a production server. Test the application by adding, editing, and deleting records in each table.

  • Add to and perform the following on the Phase 2 of the project:
    • Add a Visual Basic Windows Form Application Project to the project created in Phase 3 that will serve as the Presentation tier (user interface that includes the programming of business logic into various form controls).
    • Set the Presentation tier project to be the Startup project.
    • Add a reference in the Presentation tier to the Data tier project.
    • Add a service reference in the Presentation tier to the Data Service.
    • Add the necessary Data Grid controls and graphical user interface controls to show the data from the selected tables.
    • Make the data show up automatically when the form loads.
    • Increase the maximum received message size in the app.config file to support the data.
  • Be sure to test the functionality of the application.

In this portion, you will be preparing for system deployment and security. In the portion of this project, you will create the Distributed System Deployment and Testing Plan, which will act as a form of communications and operations policy.

  • Create a 5-page Distributed System Deployment and Testing Plan that includes the following:
    1. System overview
    2. Scope and objectives
    3. Test phases and cycles
    4. Resources
    5. Roles and responsibilities
    6. Error management
    7. Operational and communications policies
  • Be sure to reference all sources using APA style.

Make sure that the purpose of each section is stated clearly and that the Distributed System Deployment and Testing Plan serves as form of communication and documentation for the application project.

SYSTEM DEPLOYMENT AND SECURITY

System overview
Distributed systems are dual in nature implying that their deployment and testing involve
both the network subsystem testing and the application subsystem testing. It also includes
performance and security testing. The n-tier system testing will define the highest test operations
of the system and the software life cycle. In this aspect, the basic technical procedures are the
system acceptance testing/validation procedures and software qualification testing/verification
procedures.
On the other hand, network testing focus on the practical involvement as well as on formal
methods since it relates to the specific components and the entire system. Typically, system testing
emphasizes on code-level testing while distributed systems deployment and testing major on
testing of the business logic (Binder, 2010). The testing of implementations of distributed systems
covers the functionality which includes performance as well as non-functional elements that
include interoperability.
Scope and objectives
The exercise will involve formal deployment and testing processes where the main goal of
system validation testing is to establish whether or not the n-tier system meets its acceptance
requirements. However, validation testing partially covers the entire system with the intention of
showing that important, high-risk and sophisticated features of the system function appropriately.
Therefore, validation testing procedures are under verification testing process. It is a continuation
of the requirement analysis stage that involves the test team determining the components to be
tested as well as the testing environment and their corresponding teams.
