A Module is a GeneXus object designed — as explained in Modules — to make it easier to understand, maintain and integrate a Knowledge Base.
Modules do not change the Data Model; in other words, the Data Model is global to the Knowledge Base.
Please read the articles HowTo: Create a Module Object and HowTo: Open a Module Object if this is your first time using this object.
Modules were introduced in GeneXus Tilo Beta 1.
