Assignment Brief: Some of the most difficult decisions that you face as a database developer are what tables to create and what columns to place in each table, as well as how to relate the tables that you create. Normalization is the process of applying a series of rules to ensure that your database achieves optimal structure. Normal forms are a progression of these rules. Each successive normal form achieves a better database design than the previous form did. Based on your understanding for the various normal form respond to the following problems and provide the optimal answer/solution.

SportTech Events. SportTech Events SportTech Events puts on athletic events for local high school athletes. The company needs a database designed to keep track of the sponsor for the event and where the event is located. Each event needs a description, date, and cost. Separate costs are negotiated for each event.
