tableA is a table in a relational database with a composite prime key. You have determined that the table is 2NF. Owing to the fact that it is 2NF and the key is composite, is it automatically 3NF? Explain your answer. (4 points)

Lack of normalization of database tables may cause update, delete, and/or insert anomalies. You have a 2NF table, tableA, in a relational database. Give an example of an anomaly to which tableA might still be subject. Give examples to support your answer. If you believe that tableA could not be subject to an anomaly, explain why.

The relational model representation of an EERD relationship with a cardinality of (M,M) must be represented with a relationship table. Explain why this is true.

tableA is a table in a relational database with a composite prime key consisting of fields F1 and F2. You have determined that tableA is 1NF. There are four other fields in tableA. Two of them, F10 and F12, are functionally determined by F1. The other two, F50 and F55, are functionally determined by F2. Because all fields are functionally determined by at least a portion of the key, is tableA 2NF? If you believe the table is not yet...
