Problem statement:
Assume that you are an employee of a consultancy company that specializes in the analysis, design, and implementation of database systems. Southern Arkansas University (SAU) IT Group has recently approached your company with a view to implementing a database system for SAU, but they are not familiar with the development process. You are required to present an overview of the fact-finding techniques that your company intends to use to support the development of SAU’s database system. With this task in mind, create a 6-page report (Times New Roman, 12 font-size, double space) that describes each fact-finding technique and how the fact-finding techniques will be used throughout (each step of) the development of the database system.
#1 - Specify all the relationships among the records of the database shown in Figure 1.2. Please refer to the below image.
The Database Approach is the preferred method in today's business environment for database structure. Identify three reasons why this method is preferred over the File Approach.
