Part 1: Draw data models for the following entities. In each case, make certain that you show the attributes and identifiers. Also, create a relational database and insert three rows for each of the tables that you create. The data can be anything you create that fits within any constraints specified in the problem. You should submit a file with the data model drawn and the SQL used to create and populate the tables.

The IS department of a large organization makes extensive use of software modules. New applications are built, where possible, from existing modules. Software modules can also contain other modules. The IS manager realizes that she now needs a database to keep track of which modules are used in which applications or other modules. (Hint: it is helpful to think of an application as a module.) For each module it is necessary to know the name of the module, length of the module (lines of code), and the programming language it is written in.
