About declarative processing

Updated on September 10, 2021

This presentation is part of the Declarative Expressions Self-Study Course.


The whole point of declarative processing is to provide a definition or declaration for certain processing that automatically takes place, rather than having to run a specific activity.

Traditionally, you were responsible for determining when computations need to be made, and then creating the code as a sequence of steps to make them occur.  PRPC allows you to use declarative rules to simplify your processing, since you will not have to explicitly call special activities to enforce these relationships.  With declarative processing, from the standpoint of the developer, the declared expressions are simply always true, and these rules are applied or enforced automatically by PRPC when appropriate.

There are six declarative rule types in PRPC:

  1. Expressions
  2. Constraints
  3. Triggers
  4. OnChange
  5. Index
  6. Declarative Pages
