Conceptual Model for Telecomms
A Semantic Layer is a business translation layer that sits between the database and the end user.

  • Compoments in a Semantic Layer
  • Data Mart for Markets and Brands
  • Data Mart with Conformed Dimensions
  • a Dimensional Model / Data Mart which is very useful for providng data for Reports and Business Intelligence.
