- 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.
