I have a windows based .net service that handles the creation of my digital documents within an automated work flow. The .net service basically retrieves data from an SQL table as a dataset and then pushes(binds this dataset to a crystal reports 8.5). I have been tasked with rewriting this service and I am at a crossroads where I have to decide if I want to use push or pull method. The service is going to be using .net framework 4.0 and crystal reports 2008. It's a 24 hour service that sits on a server that has nothing else running but the service. It's a critical application, the volume is pretty high sometimes upto 300 jobs. The service basically will overlay the text(dataset) on to the Crystal report. We do often add new templates, which method is ideal push or pull for such an application.
