Though most developers have heard of the SQL Model clause in 10g, many may baulk at the idea of using it - daunted by seemingly foreign syntax that might well have come out of a FORTRAN program.
Look a little closer and you'll find it's just like building a spreadsheet. Concise, easy to read syntax that provides the functionality for demanding calculations that would normally require elaborate joins, unions, analytics or PL/SQL. In addition to the development and maintenance burden, we are also faced with the all too familiar problem of business customers duplicating data to an Excel spreadsheet that is shared and erroneously modified around the workplace.
This session uses the Model clause as a high performance tool that can simplify approaches to every day problems. It demonstrates that Model is an extension to SQL that forms multi-dimensional arrays with inter-row & inter-array calculations that automatically resolves formula dependencies.
