Validation and verification in a robust program

Ever wondered what the exam boards mean by a robust program? Here is a working example of a robust program created in Python. It includes the Python program, an SQL database it links to along with a walkthrough PDF explaining the main points of the program.

The program displays the following programming skills:

• Selection
• Iteration
• String manipulation
• Using logical and Boolean operators
• Creating and calling subprograms
• Passing variables between subprograms
• Validation
• Verification
• Writing to and reading from an external file
• Searching for data using SQL
• Good programming practice

Please note: This is a robust program, however that does not make it indestructible :)
