End of the training you will be able to create and administer your own MySQL Database and manage data. Set to SOURCE by default. The data types in the columns must also be comparable. To create an external table with SQL, specify a LOCATION path in your CREATE TABLE statement. Each consecutive normal form depends on the previous one.The first three normal forms are usually adequate. It utilizes the if-then rules which are equally exhaustive and mutually exclusive in classification. When those change outside of Spark SQL, users should call this function to invalidate the cache.
