I want to expose our internal bussiness data through odbc driver. One of the propitary product that i found is DataDirect OpenAccess. I want to use SQL to query live data from our data source. Writing my own SQLEngine will take ages but i need something like following diagram. We intend to use it on live data so exporting it to database and than running query is not a good solution at this time. Can anyone guide me how can i solve it using opensource.
