Hi Phani,
Yes HANA is database which is supported by good modelling tools.
We have a model called "Analytic View" in HANA which supports Mutli-Dimensional modelling very similar to Star Schema and it uses OLAP engine.
May be you should give a start on learning HANA developer guide, HANA Modeller guide and then try to understand so that you can get a idea of it.
