In a previous tutorial, we normalised an aircraft ownership register (Normalisation: Representing Relationships in a Database). In this tutorial we are going to create a small application that demonstrates how to manipulate records in a group of related, normalised tables.
The primary table in this illustration is the Aircraft Ownership Table which is a Map of two tables Aircraft Table to Owner Information. A Map is typical a table containing secondary keys that represent more-to-more relationships between two tables.
