Let me try

What in particular are you trying to marry between the two datasets?

I try to find some application by name And the first interested things that is to know if this process is already running..

I don't believe I understand your goal. Are you asking for a query that looks for: 1. All installed applications 2. Whether each installed application has a running process (eg. Microsoft Office Word 2020 is open and running)

yes

If you are trying to query user behavior you are better off querying the

userassist

table which has thing like '# of times opened', 'last opened'.
