When expressor first came to market in 2008 it was targeting very high performance for complex transformations. However, it subsequently changed its go-to-market model to the structure seen today. In our view this was a sensible change. We are firmly of the belief that the use of semantics is the way forward in many technology areas, of which data integration is just one. When combined with the product's extensive support for parallelism it is our opinion that expressor offers significant advantages over traditional methods in terms of ease of use, reuse and performance.
