Make up a scenario from a subject/industry area of your choosing, and invent a single relation that has at least one partial dependency (i.e. one that is in 1NF, but not 2NF). Supply your relation below using the proper notation from class. Explain why the dependency(s) is/are a problem specifically in the scenario you chose. Normalize your relation to 2NF   Do the same thing as you did above, but this time start with a relation that has no partial dependencies, and at least one transitive dependency (2NF but not yet 3NF). Normalize to 3NF.

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.
