For testing purpose, create a database named as hw3_yourname_l3sid on any relational database engine (where l3sid is the last three digits of your student id). use the enclosed database scripts (for microsoft sql and mysql) as reference to create necessary tables and populate tables with data. note you may utilize any relational database engine (not limited to microsoft sql and mysql). however, answer all queries by using standard sql, not something specific to a particular db engine. also note the result set of each query may or may not be empty – it depends on data in tables.
