Hands-On Software Engineering with Python

Selecting a data storage option

Looking at the logical architecture for hms_sys, and allowing for a local data store for the Artisan Application that wasn't in the original diagram, there are three databases that development needs to be concerned with:

The Web-Store Database is attached to the Web-Store Application, and cannot be modified as a result. The current expectation is that modifications to data in that database will be handled by a call to the API that the Web-Store Application makes available. At this point, then, data access to and from this database can be set aside.

The artisan Database, on the other hand, doesn't exist yet
