Camunda BPM and Existing External Application

[aravindhrs]

Hi @Maysa ,

Database(RDBMS) is prerequisite for camunda application. You can check supported databases and the version compatibility table here:

Which Camunda version is the most stable today

@nickjonson camunda version 7.11 version is the stable version. Also you can check the camunda and spring boot version compatibility matrix here

@Maysa

I want to remove the business logic from the application and create it in Camunda BPM using Modeler and DMN.

Extract the code which is only required for process execution flow, incase your process application is shared/container managed or standalone process application.

Another option is, without extracting the code from the business application you can embed the process engine with in the existing application itself.

@Maysa

create it in Camunda BPM using Modeler and DMN. To do that I will need to read from the SQL database, feed the data to the DMN decision table and then based on the output of the DMN I will need to update or insert records into the SQL database.

DMN usage is depends on your business usecase, also DMN is optional. In your applictaion if you have the requirements for business decisions, then opt for DMN.

@Maysa

So can I achieve this with Camunda BPM and communicate this way with the external application?

Overall, its possible to setup camunda for your business usecase.

@Maysa
