Don't know how to phrase the question and where to find the answer, I hope for your help and tips community.
There is a database (currently on paper) the structure of which is similar to the following:
the number of objects in each of the many sub objects in them under a lot of equipment, each equipment a number of properties. And all no matter what, but the various parts of this structure are further grouped according to various criteria.
I would like all these data to drive program under the OS (which would always have on hand) which is a quick search for any subject and on specified groups. Advise please the program with similar functionality, preferably with a simple user interface.
