Extend Camunda Platform

I trying to improve the automation of business processes, make automated business process running instantly and use the camunda database,
In order to do that and for customization camunda to platfome that has the ability to recognizes the existing impacts and effects between running process instances at rum time and manages them according to the manager’s instructions, for example,
if there is a process instance that affects another instance, the
system should identify the instance to behave accordingly.
Anyone can help me? or, it is possible to add storge in the backend/ database of Camunda platform?
