Do I require Microsoft SQL Server to run the PRS?

No, the current version of the PRS uses the Microsoft Jet Database Engine. PRS performance has been heavily optimized in terms of both shared database design (indices and normalization) and at the client (with aggressive local caching of data).


The PRS application is not transaction intensive — both our experience and benchmarks have shown that performance is influenced primarily by client PC and network performance.


As always, when measuring the performance of any application you should benchmark the application (in it's target environment) and not the implementation tools (database benchmarks are, by definition, transaction intensive and seldom benchmark the client side GUI).
