Chapter 9. APEX Processes

APEX Processes allow us to implement the application logic. As with APEX Computations, APEX Processes are also included in both the Page Rendering and Page Processing phases. The similarity continues with APEX's support of application and page level Processes. Some of the APEX Processes are fully declarative, while with others, we need to use SQL and PL/SQL code to achieve our goals.

Note

APEX Computations can be considered as a private case of APEX Processes. We can use APEX Processes to implement every APEX Computation. So, why do we need APEX Computations? Some of the APEX Computations declarative options, e.g. Static Assignment or Item Value, cannot be implemented declaratively with APEX Processes, but require the use of PL/SQL code. You can look at some of the APEX Computation capabilities as a declarative extension of APEX Processes.

In this chapter, we will review the following issues:

• The main concepts of APEX processes and how they can help us to implement...
