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.
It is recommended that the following be covered in every training session for a new user of the school database:
Which of the studied data structures in this course would be the most appropriate choice for the following tasks? And Why?   a) A training institute needs to maintain a database of 2000 identification numbers of trainees who received an ICDL certification. The goal is to find rapidly whether or not a given ID is in the database. Ordering information among the identification numbers is not important; speed of response is very important; efficient use of memory is also important, but not as important as speed of response.   b) A large fixed content of data needs to be maintained. It is sorted and the admin needs to search for and retrieve existing items, but no new/existing items will be inserted/deleted. You may assume that the data can fit inside the memory of the computer.   c) A transposition table is a cache of previously seen positions in a game tree generated by a computer game playing program. If a position recurs via a different sequence of moves, the value of the position is…
