Chapter 3. Database and Data Objects
It is in the nature of a content management system that the database is at its heart. Before we get into the more CMS-specific questions about handling different kinds of users, it is worth considering how best to handle storage of data in a database. Applications for the web often follow similar patterns of data access, so we will develop the database aspect of the framework to offer methods that handle them easily. A relational database holds not just data, but also information about data. This is often underutilized. Our aim is to take advantage of it to make easier the inevitable changes in evolving systems, and to create simple but powerful data objects. Ancillary considerations such as security, efficiency, and standards compliance are never far away.
The problem
Building methods that:
Handle common patterns of data manipulation securely and efficiently
Help ease the database changes needed as data requirements evolve
Provide powerful data objects...
