Workflow Engine


The workflow engine of this app is a system to handle business logic.

Whereas the database consists of neutral things (fields, records, lists), the workflow engine weaves additional attributes around it, that indicate additional constraints.

These additional workflow attributes are computed by the server on the fly, and then stored in a separate table in the database: workflow. From then on the following happens with the workflow attributes:

  • the server uses the workflow info to enforce the business logic;
  • the server updates the workflow attributes after any insert/update/delete action.
