 write an article on Data design

Writing

 write an article on Data design. It needs to be at least 500 words. Source document for advertisements coming in to the advertisement company. 2. Suggest at least four user interface design guidelines that could be used for the new system.

a. Consistency: There are certain aspects that must be consistent. For instance the interface should be consistent to make the system user friendly and easier to use. The terminology amd the icons should also have a level of consistency between the screens (Fidel Captain. Six-Step Relational Database Design(TM): A step by step approach to relational database design and development Second Edition page 176).

b. Simplicity: The system should have the capability to break down complex tasks such that they are reduced to small and easier tasks. Also, the long sequences that are to be integrated into the system should be turned into separate sequences in order to ease the procedure of processing information (Terry Halpin, Tony Morgan, Morgan Kaufmann Information Modeling and Relational Databases, Second Edition, March 2008. page 134).

c. Feedback: The system should have the capability to provide feedback which is articulate, informative and semantically correct. This will ensure that the information displayed on the user and the client side is reliable and correctly understood (Terry Halpin, Tony Morgan, Morgan Kaufmann Information Modeling and Relational Databases, Second Edition, March 2008 page. 136).

d. System messages: The system should be able to provide user centered messages like error messages. (Terry Halpin, Tony Morgan, Morgan Kaufmann Information Modeling and Relational Databases, Second Edition, March 2008 page 139). The system should also avoid using threatening messages or alarming messages.

e. Display: The display between screens should be consistent and must show some degree of inertia. Unnecessary information should be avoided since they will be of no use and the interface should use easily recognizable icons. (Ramez Elmasri, Shamkant Navathe, Addison-Wesley Fundamentals of Database Systems (6th Edition), April 2010. Page 143).

3. Suggest several types of controls that might be used on the switchboard you plan to design. Explain why you chose each control, and create a storyboard that shows the switchboard layout.

Some of the controls that can be used on the switchboard are:

a) Images: This control can be used to insert the picture of the dog and display it on the advertisement site.

b) Text: The text can be used to provide a description of the dog and give the necessary information concerning the dog.

c) Boxes: This control can be used to tick where the services available for the dog appear. For instance, the dog can either be for sale or for hire.

d) Charts/graphs: These can be used to show the progress of the different services available for the dogs.
