Database Abstraction

For the last couple weeks, I’ve talked about creating database abstractions. In the first article, I spoke about the need for creating a high-level API, on top of standard WordPress APIs to act as a CRUD interface for your projects. The second was about using classes with all static methods for validation and storage of options. In part three, I want to talk about dependency injection and illustrate the value of this concept by offering a different way to create a database abstraction than I did before. What I showed in the last article works for its purpose. But, that […]
