Multiple databases

We are in a planning stage to do the following: Which are different ways , one can have the following scenario. The processing invloves data from different companies ( A service buereuo type) The issues are
To seggregate the client data .
To access the core look up tables from a central database/area. The other tables (VERY LARGE) , with the same names , will be in different areas
To use the same set of programs(without much customization ) To give options to the operators to run the programs on the data they want to .
To efficiently manage the data (backup/recovery/scheduling the jobs)

Any inputs will be appreciated.
