The Map Editor enables you to define source and target connections to the required files, tables or entities, manipulate and process the source data using the event model and scripting language, and then write the data to the specified target(s). The user interface for the Map Editor has four distinct tabs (Source, Target, Mapping, and Configuration). You can connect to various sources and targets within the UI, then save and reuse these connections in other maps. For more information about maps, see Designing and Executing Map.
