Add generation capabilities and/or tailor the built-in functionality of generator. This enables you to produce "all" the test data for the MySQL tables you produced in the previous assignment. You do not need to populate data to the tables in this assignment (which will be the task in the next assignment) but you must become able to generate all the realistic data required for the proposed information analysis. You are not allowed to use other software tools (such as Microsoft Excel) to generate data. You are not allowed to use "existing data" to skip this assignment. Any non-trivial extension from the statistical viewpoint concerning the data nature (like the above assigned functionality) will receive extra credit.
