Why Microsoft BI Semantic model is the future and what benefits it provides as compared to multi-dimensional cube?

Tabular model solutions use relational modeling constructs such as tables and relationships for modeling data, and the xVelocity in-memory analytics engine for storing and calculating data..Microsoft BI Semantic model is faster to design, test, and deploy. And it will work better with the latest self-service BI applications from Microsoft. Microsoft has correctly identified that many people want to do BI but were put off by the complexity of building Multidimensional models in previous versions of Analysis Services. The simplicity of the Tabular model goes a long way to solving this problem.
