Updating sql database from an array

Data normalization is primarily important in the transactional, or online transactional processing (OLTP), database world, in which data modifications (e.g., inserts, updates, deletes) occur rapidly and randomly throughout the stored data.

In contrast, a data warehouse contains a large amount of denormalized and summarized data—precalculated to avoid the performance penalty of ad hoc joins.

After you've created the database framework, you must organize the files in such a way that you can easily manage them.

One cornerstone of database design and data normalization is that data organization for storage differs from the information most people want to see.
