Design Document

Write a 6–10 page design document in which you:

Support the need for the use of relational databases and data warehousing. From a management standpoint, it may be important to show the efficiencies that can be gained for executive oversight.

Create a database schema that supports the company’s business and processes. Explain and support the database schema with relevant arguments that support the rationale for the structure. Note: The minimum requirement for the schema should entail the tables, fields, relationships, views, and indexes.

Identify and create database tables with appropriate field-naming conventions. Then, identify primary keys and foreign keys, and explain how referential integrity will be achieved. Normalize the database tables to third normal form (3NF).

Identify and create an Entity-Relationship (E-R) Diagram relating the tables of the database schema through the use of graphical tools in Microsoft Visio or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length but must be included in the design document appendix. Explain the rationale behind the design of your E-R Diagram.

Identify and create a Data Flow Diagram (DFD) relating the tables of your database schema through the use of graphical tools in Microsoft Visio or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length but must be included in the design document appendix. Explain the rationale behind the design of your DFD.
