Limitations and considerations

We have less flexibility with the WordPress built-in database than when we design a database from scratch. Limitations and features unique to WordPress need to be understood clearly to make full use of the framework and avoid potential bottlenecks. Let's find out some of the WordPress-specific features and their usage in web applications.

Transaction support

In advanced applications, we can have multiple database queries, which need to be executed inside a single process. We have to make sure that either all queries get executed successfully or none of them get executed, to maintain the consistency of the data. This process is known as transaction management in application development. In simple website development, we rarely get such requirements for handling transactions.
