The goal of this chapter was to understand the role of default database tables and how we can adapt them to our requirements. We started by analyzing the database relationship diagram and identifying connections between tables. We also looked at the role of each database table with commonly used data.
We identified the need for knowing proper database usage of core features, and explored various ways of tracking database usage for each feature. Then, we had a brief overview of database structure in multisites and how it varies from that of a single site database. Finally, we looked at various functions for querying both default tables and custom tables.
In Chapter 3, Designing Flexible Frontends with Theme Development, we will be starting the development process by working with child themes, theme templates, and dynamic theme components.
