Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.

Please draw an relational ERD with multiplicities and all the attributes based on following description: ( Please identify the primary key in each entity.) An Adult Education Department runs various courses during the daytime and evenings, and at different times of the year. For example, ‘Spanish level 1’ is offered on Monday mornings, Monday evenings or Wednesday evenings, and runs over 25 weeks from October to March. On the other hand, ‘Introduction to Digging Up Your Ancestors’ only runs for 8 weeks, but is offered on Tuesday or Wednesday evenings from October to December, January to March, and April to June, with an optional field week in August. There is always a maximum number of places for each course offering, which is dependent on the individual teacher. For example, ‘Spanish level 1’ on Monday evenings may be limited to 20 places, but on Wednesday evenings the limit may be 25. Each course offering is only taken by one teacher, however teacher may take…
