Why did SAP build a database?
HANA is a realization of Hasso Plattner’s idea of a single in-memory columnar database for OLTP AND OLAP workloads. Hasso believed that if a database could be built with a zero response time, that business applications would be written fundamentally differently – and IT landscapes could be simplified.
Modules of SAP
is an application that uses in-memory database technology that allows the processing of massive amounts of real-time data in a short time. SAP S/4HANA, SAP ECC FI,SAP SCM, SAP HCM, SAP BI This are the letest SAP HANA Modules

SAP HANA fundamentally different?
HANA leverages the modern hardware technology. It uses large main memories and massive parallel processing on multi-core CPU’s. Due to this, the access speed increases and response time decreases.
It stores all data in-memory and in a columnar format (via encoding). Though, it is both row and column stored. Due to columnar structure many of the transactions like aggregations become quite fast. And, this can reduce the database footprint by 95%.
All the operations are carried on demand, in the memory. This makes it possible to run OLTP and analytics applications in a single instance.
Apart from this, HANA also has certain mechanisms like delta storage and row-level insert and update performance.
Also, SAP HANA has added bunch of functionalities like data virtualization, search, text analysis, geospatial etc
