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. Your responsibilities at Domain.com include the design and development of application frameworks. Domain.com operates as a financial institution. You are currently developing a Microsoft Windows Forms application for Domain.com that is meant to allow bank tellers to manage account transactions for the Domain.com customers. In the United States of America is it government policy that all transactions to the value of $10 000 or greater must be reported. Domain.com need to comply with this policy. This policy also states that the government should be informed as to who made the large transaction. The logical design suggests that in the event of a teller managing a transaction for a customer that is $ 10,000 or greater in value logging of the following information should occur:
1. Date and time
2. Customer account number
3. Transaction amount
4. Transaction type

When subjected to government audit, Domain.com needs to have peace of mind that they are in compliance with the government policies. Thus you now need to decide whether or not the design meets the requirements for compliance.

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. Your responsibilities at Domain.com include the design and development of application frameworks.
You are currently developing a Microsoft Windows Forms monitoring application for Domain.com. This application is destined to read data in a Microsoft SQL Server 2005 database and display it graphically on a form. All Domain.com users need to be able to:
1. choose the refresh rate for displaying data
2. choose an interval in multiples of one second
To this end you need to reuse a component to meet these requirements without requiring excessive coding.

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. Your responsibilities at Domain.com include the design and development of application frameworks. Domain.com operates as a medical technological company that manufactures electronic scanning equipment for medical use. You are currently developing a Microsoft Windows Forms application. This application is destined to allow doctors to perform computed Axial Tomography (CAT) scans on patients. When a CAT scan is carried out, it takes over 1,000 two-dimensional scans that are combined to create a three-dimensional image. It takes no more than two seconds to make a two-dimensional scan, however it also takes approximately 20 seconds to combine each image. The Microsoft Windows Forms application that you are developing must allow doctors to take the two-dimensional scans without requiring the patients to wait for a long time. You thus need to choose the appropriate component to meet this requirement.

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. Your responsibilities at Domain.com include the design and development of applications. You are currently developing an Extensible Markup Language (XML) Web service that when completed will allow client applications the ability to download movie clips. One of the requirements that should be met is that all Web service clients must be able to use the Web service. You should also keep in mind that you should optimize the message transfer for some of the movie clips since fifty percent of the movie clips are quite large.
To this end you decide to make use of Microsoft Visual Studio 2005 and Web Services Enhancements (WSE) 3.0 to develop the Web service. Now you need to modify the Web.config file to meet the requirements.

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. Your responsibilities at Domain.com include the design and development of applications. Domain.com operates as an umbrella company for several recording houses in the music industry.
You are currently developing an enterprise application for Domain.com. you need to design the database schema for this application and following are the facts regarding record labels/recording house, albums, songs, and artists; pertaining to the company that you need to take into account in your design:
1. A label has one or more albums.
2. A label has one or more artists.
3. An artist records zero or more albums.
4. An artist records one or more songs.
5. An artist belongs to one label.
6. An album is recorded by one or more artists.
7. An album has one or more songs.
8. An album is owned by one label.
9. A song is recorded by one or more artists.
10. A song exists on one or more albums.

You need to normalize the database. To this end you need to decide on the amount of tables to use in the database.

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. Your responsibilities at Domain.com include the design and development of applications. Domain.com operates as an Independent Electoral Commission. You are currently developing a voter registration application for Domain.com. Following is a list of the facts that must be taken into account:
1. A voter is associated with one political party.
2. A voter has one mailing address.
3. A mailing address can belong to multiple voters.
4. It is estimated that on average each mailing address can be used by two voters.
5. A voter has two telephone contact numbers.
6. A contact phone number can belong to multiple voters.
7. It is estimated that on average each contact phone number can be used by two voters.

The plan is to design the database schema based on these facts. Now you need to decide on the minimum number of tables that will be required. In your solution you must ensure that it offers the best performance.

What should you do? (Choose the correct amount of tables required.)

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. Your responsibilities at Domain.com include the design and development of applications. Domain.com operates as a service provider in the security industry. You are currently developing a video surveillance application for Domain.com. You need to implement a class named Visuals. Visuals will be destined to control access to a video camera. A method named CommenceRecording must start a recording session of the camera if one is not already started. In the event of a recording session having started already when the method is called, you have to interrupt the execution of the application. To this end you now need to define the Visuals class.

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. Your responsibilities at Domain.com include the design and development of applications. You are currently developing a business logic component that is used in a line-of-business (LOB) application. The business logic component calls a Web method named SeeCustomer in an Extensible Markup Language (XML) Web service. The SeeCustomer Web method throws an exception of a type SoapExtension in the event of the specified customer being non-existent. Now, when this exception is thrown, you must call a Web method named NewCustomer. To this end you need to implement the appropriate exception handling mechanism to meet this requirement.

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. Your responsibilities at Domain.com include the design and development of applications. Domain.com operates as the Emergency unit of the Traffic Department. You are currently busy implementing a Microsoft .NET Remoting component. This component will be used in the traffic control environment. The component will allow the traffic department to guide all traffic officers on duty to the available alternative routes during emergencies. As such the component must meet the following requirements:
1. A specific instance of the component must be allowed to control access to the navigational system on one traffic officer’s vehicle.
2. The component must be instantiated only once while the traffic officer’s navigational system is being controlled.
3. The component must be hosted on a server that is separate from the application. To this end the design suggests making us of single-call activation over Transmission Control Protocol (TCP). You are now required to decide whether or not the design meets the requirements.
