Does anyone know if a substitute exists for sql? I mean besides MS SQL and Oracle and all that jazz. Thanks. You know, the thing about SQL is, that there is virtually nothing that can replace it.

I just wanted to add that Linq checks optimistic concurrency on each column by default using the column's Update Check property. So you can avoid altering the tables by adding the timestamp column.

I would just bite the bullet and add the timestamps and let LINQ to SQL handle the concurrency checks. @Fer,
