Table Design...Did I make a mistake?
I have build a database that contains 3 main tables. Though each table has
data that refers to one element. They are for physician information and are set up as follows: The first table is contact information The second is volume type info and the third is outcome type info. All fields are linked to one physician, however, each physician has several quarters of data. I am running into a problem that in my form, when i add a new record for a new quarter of values it is overwriting my previous data. Should i have set my tables up differently?

How are the tables related to each other? Are you saying that each table
holds a "PhysicianID"? So how many Outcome records can you have for each physician (depends on your primary key)? If you can only have one, there's the reason new data is overwriting the old data ... you can only have one record per physician?! More info, please...

Yes, each table holds a physicianID. Each physician will have 50 or so
idicators to track each quarter. Does this help? "Jeff Boyce" wrote: How are the tables related to each other? Are you saying that each table holds a "PhysicianID"?

Colby
If you are saying that each physician can only have one record in the Outcomes table, that is your problem. If the relationship between physicians and outcomes is "one-to-many", you need a table in which you can store one row/record for EACH physician/outcome combination, not one for ALL (that would be ... a spreadsheet!). Good luck! Regards Jeff Boyce Microsoft Office/Access MVP "Colby" wrote in message ... Yes, each table holds a physicianID. Each physician will have 50 or so idicators to track each quarter.
