Processes

A collection of methods that make interaction with coreDB more straight-forward.

This prevents someone from having to re-write database statements many times, that might turn out to be erroneous or inconsistent when not careful. These methods are related to operations regarding processes and workflows.

get_processes_by_workflow_name(workflow_name)

Get all processes for a given workflow name.

count_incomplete_validate_products()

Returns:
