CIS 498 Strayer University Database and Programming Design Paper

One (1) of the main functions of any business is to transform data into information. The use of relational databases has gained recognition as a standard for organizations and business transactions. A quality database design makes the flow of data seamless. The database schema is the foundation of the relational database. The schema defines the tables, fields, relationships, views, indexes, and other elements. The schema should be created by envisioning the business, processes, and workflow of the company. 

Section 1: Design Document

1. Write a five to ten (5-10) page design document      in which you:
   1. Create a database schema that supports the       company’s business and processes. 
   2. 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.
   3. Create database tables with appropriate field-naming       conventions. Then, identify primary keys and foreign keys, and explain       how referential integrity will be achieved. 
   4. Normalize the database tables to third normal       form (3NF). 
   5. Create an Entity-Relationship (E-R) Diagram 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.
   6. Explain your rationale behind the design of your       E-R Diagram. 
   7. Create a Data Flow Diagram (DFD) 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.
   8. Explain your rationale behind the design of your       DFD. 
   9. Create at least two (2) sample queries that will       support the organizational reporting needs.
   10. Create at least two (2) screen layouts that       illustrate the interface that organizational users will utilize.

Section 2: Revised Gantt Chart / Project Plan

Use Microsoft Project or an open source alternative, such as Open Project, to:

1. Update the Gantt chart or project plan (summary      and detail) template, from Project      Deliverable 2: Business Requirements, with all the project tasks.
