Biztalk Map Question:

Maps are graphical representations of XSLT (Extensible Stylesheet Language Transformation) documents that allow us to perform, in a simple and visual manner, transformations between XML messages. A map file basically is the XML file that defines the correspondence between the records and fields in one schema and the records and fields in another schema. You create a map when you want to transform or translate data that you receive or send from one schema to another.
