Regys Mene, Hartmut Westenberger and Hrvoje Husic analyze in their publication „Reference Models for the Standardization and Automation of Data Warehouse Architecture including SAP Solutions“ the relation between SAP’s Layer Scalable Architecture (LSA) and the Data Warehouse Architectural Reference Model (DWARM).
While LSA was primarily designed to standardize and automate a SAP centric BI architecture, DWARM is not platform-related. Mapping LSA on DWARM supports embedding of SAP building blocks in a heterogeneous BI landscape.
