Thanks Tom! the end goal is a single report (this would be done in 4D), summarizing information across all 4 commercial applications. What I know about the internal workings of any of the 4 sql programs = 0 From the description - there is no official outline of the report yet - each program contains information regarding 'projects'. - each program was written/maintained by separate software developers - each program has part of the data needed for the desired final report product
I am currently in the 'can this be done?' phase, so I am just trying to get a feel for what is reasonable to be able to do. However, honestly, even if I can get schema and raw data access - I am not sure that coordination of all the data will be practical, let alone possible - especially with little or no input from the 4 vendors.......
