![]() In this survey we identify critical knowledge gaps in MDA and DWs and make a chart for future research to motivate researchers to close this breach and improve DW solution's quality and performance, and also minimize drawbacks and limitations. However, there is a room to improve further the DW development using MDA concepts. ![]() Furthermore, they addressed the conceptual modeling of QoS parameters such as Security in early stages of system development using MDA concepts. Their focus was on automatic creation of Multidimensional model (Start schema) from Conceptual Models. In the last few years, many researchers tried to apply MDA to Data Warehouse Systems (DW). Model driven architecture (MDA) is playing a major role in today's system development methodologies.
