This mini-project has two parts; each part may be submitted independently. Results may be submitted using one of the documentation options identified in a separate document. Consult the document Documenting SQL in Class Content -> Oracle 11g XE. The files containing the schema and sample data for the Company database and the schema for the Sales database are posted in Class Content -> Scripts.

Submission Instructions
1.    Include your name and the assignment identification at the beginning of the Notepad file.
2.    Identify each problem. You may insert the problem number or copy the problem number and text of the problem into the Notepad Wordpad file.
3.    Edit the Notepad or Wordpad file to remove incorrect attempts that may accumulate as you complete the assignment. This is especially important in a spool file.
4.    If you are using the GUI, include the same information (name, assignment, problem identification) along with the screen snapshots. Remember that these will be very large files.
5.    Submit all documents to the assignment. You may upload as many documents as necessary for the assignment.
