Populate the tables with test data

Assignment Help PL-SQL Programming
Reference no: EM13334327

The final design should be tested to ensure it will meet the requirements for the sanctuaries. You need to produce appropriate test data to populate your tables and devise some queries that would test the design. Think about the type of queries that would be needed by the different types of users, for example, the employees, volunteers, potential volunteers and sponsors.

Give thought to what data should be added. As a minimum, each table should have at least 3 rows in it, but some should be more. Basically, the tables at the many end of a relationship should contain more data than the relation at the one end.

To summarise:
• Implement the DDL script produced by the Data Modeler tool in Oracle.

• Populate the tables with test data

• Produce 5 SQL queries to test your design.

These must include at least one query that involves:
• A join
• An aggregate function, such as count, avg, etc.
• A selection (that is not all rows and columns are returned)

Credit will be given to queries that are not trivial, for example, "SELECT * FROM Tablename" is unlikely to gain more than one mark. SQL Developer can be used to produce the queries and populate the tables.
