I am trying to set up a system to create a relational database layer that sits on top of a collection of TTrees. THe relational database will keep track of all events generated in my experiment and generate a unique event identifier for each event. If I desire to load particular event data for a particular event ID, I can query the relational database, which will tell me which TTree structure stores the data I desire.
Has anyone implmented a system providing the described features. If not, do you know whether this can be done within root itself - for example using a ttree structure to keep track of the relational information.
Do I need an object database for this?
Any information would be greatly appreciated.
If I have not been clear about the requirements of this project, I can provide more information.
