RDBMS Project This project provided a list of columns and business rules that are to be used as a guide for development of the proposed PiggyBank database. The goal is a database in the third normal form but the developer is allowed to denormalize for a valid business reason. The column list that is provided has redundancies and new columns may be necessary. The developer is to make the best choices for primary and foreign key constraints. The expected deliverable is an ER diagram with crows-foot notation.
Bank Project We are given a modified version of the ER diagram we developed earlier and tasked with developing stored procedures for the following: Create new customer and update customer Create new account (savings or checking), update account status and add user Change account status, close account, reactivate account Deposit, Withdrawal and Transfer Overdraft setup (general and specific accounts) ATM procedures Show balance for last five transactions Show transaction history for the last 30 days Additionally create a trigger to prevent drop and alteration of tables plus a trigger to prevent deletes and updates to the transaction table (and any others deemed necessary)

Library Project A database has been created to support the principal functions of a lending library’s day-to-day operations: adding new members (adult and juvenile), checking books out and in, adding new books, renewing memberships, changing a juvenile record to an adult record once the juvenile reaches 18 and updating adult record information. Books are identified by International Standard Book Number (ISBN). Books with the same title will have different ISBN based upon language and cover type. The library also holds multiple copies of each ISBN. Loan history is considered critical information and must be kept indefinitely. Library memberships are good for one year from issue date. Adults are issued memberships and juveniles are associated with an adult sponsor until they reach 18. Books are checked out for 14 days and members may have only 4 books out at any one time. The deliverable is to create stored procedures to support system functionality and any necessary views and a variety of reports that can be viewed online.

Online Movie Project The online movie rental company, BlockFlix, has stores nationwide and is creating a centralized database for tracking inventory, sales, customers and memberships. The stores rent VHS movies, DVD’s and video games as well as selling new and used movies, movie memorabilia, games, game consoles, snack foods and drinks. A new website will be created that uses the database to rent movies online. Database access must be through stored procedures. All inventory is received at one location and distributed to stores. Stores have ancillary kiosk locations in supermarkets and other retail locations that allow member or non-member rentals at $ 1.00 per day per movie. Online and store customers purchase a yearly membership at one of six levels with right to a certain number of movies out at any one time based upon their membership level. Additionally each member will have a queue of movies they would like to be mailed to them as they return movies as specified by their membership level. Management is expecting a high-availability database solution and mandate that all transactions are to be stored indefinitely within the database.
