“Diffing” objects from a relational database

Question

Our win32 application assembles objects from the data in a number of tables in a MySQL relational database. Of such an object, multiple revisions are stored in the database.

Answer 1

My application dbscript compares hierarchical data (database schemas) in a stored procedure, which of course has to compare each field/property of every object with its counterpart. I guess you won't get around that step (unless you have a generic object description model)

As for the UI part of your question, have a look at screenshots to view and select differences.
