Tools for the semantic layer
There are several different tools for implementing the semantic layer, as follows:
- SQL Server Analysis Services (SSAS): SSAS is part of the SQL Server services. It is primarily deployed on-premises, meaning it is hosted within an organization’s local infrastructure. SSAS offers a robust and scalable platform for building multidimensional and tabular models. Initially, only multidimensional models were supported, but due to popular demand, tabular model support was added later. Multidimensional models are designed for complex analytical scenarios and support features such as hierarchies, calculated members, and advanced aggregation capabilities. Tabular models, on the other hand, provide a simpler and more intuitive approach to data modeling, allowing users to create analytical models using tables and relationships. SSAS also includes advanced features such as data mining and data visualization.
