You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. The design of applications forms part of your responsibilities at Domain.com. Certkiller .Com operates as a telecommunications company.
You are currently busy implementing a solution for Domain.com that will, when completed, consist of five Microsoft Windows Forms applications, two Microsoft ASP.NET Web applications, and twenty Extensible Markup Language (XML) Web services. The Web services will be used by the Windows Forms applications as well as the Web applications to access business functionality.

* The Web services: All the Web services have similar configuration requirements. However, only five of the Web services will make use of Simple Object Access Protocol (SOAP) header authentication.

* The two Microsoft ASP.NET Web applications: Both of these applications have different configuration requirements. However, both of them require integrated Windows authentication.

* The five Microsoft Windows Forms applications: All these applications makes use of integrated Windows authentication.

The Web applications and the Web services are destined to be hosted on a server that will be running Microsoft Internet Information Services (IIS) 6.0. Following is the design of the Microsoft Visual Studio 2005 project structure:
1. One project for each Windows Forms application.
2. One project for each Web application.
3. One project for each XML Web service.

You have been instructed to evaluate the design for maintainability and thus you need to draw a conclusion regarding the maintainability for the design.

All servers in the domain run Windows Server 2003. The design of applications forms part of your responsibilities at Domain.com. Domain.com operates as a cosmetics company.
You are currently busy developing an enterprise application for Domain.com. This application must be able to support the ability to access chemical data. This chemical data are stored in five relational databases. The chemical makeup of each product is represented as a business entity. The business logic determines how the chemical makeup can be used in combinations to create new products. You need to evaluate the design in terms of the best performance that is can offer. Following are the physical design aspects that you should take into account in you evaluation:
1. One assembly for all business entities.
2. One assembly to contain business logic.
3. An assembly per type of database.

1. In the event of a driver exceeding the speed limit by more than 10 and less than 20 kilometers per hour (KPH) – the corresponding fine should be $100 with an additional amount of $10 for each KPH over the limit.
2. In the event of a driver exceeding the speed limit by 20 or more KPH, the corresponding fine should be $250 with an additional $25 for each KPH over the limit.
To this end you write the following pseudo-code to address the requirements:
DECLARE speedLimit INTEGER
DECLARE speed INTEGER
DECLARE fine INTEGER

Now you need to complete the pseudo-code.
