Many of the databases will be small, with one or two tables. But as the databases become braver, tackling bigger projects, it will be noticed that the design of the tables in proving problematic. The SQL written starts to become unmanageable and data anomalies start to creep in. This means it is time to learn about database normalization, or the optimization of tables.
