I have a non relational SQL database, this one has been created by a tool named "Wizard Upsizing" in Visual Foxpro. My apps are coded in Visual Foxpro and I don't want to modify them. I would like to make my SQL database relational (added fields, tables, etc). Is it possible to reorganize dynamically (in sync) the data in the new database structure, without changing on client side. By example, I wonder if using of trigger to replicate changes between old & new structure could be possible and acceptable (at level of performance, etc)?
