Overview of SAP HANA | Advantages of SAP HANA | SAP HANA Online Tutorials


What is SAP HANA?

SAP HANA is a data platform with in-built memory marketed by SAP SE. SAP HANA is deployable in the cloud. It is a progressive platform that is most suitable for performing real-time analytics and developing and deploying real-time applications. SAP HANA is an evolution in the field of the database, (Learn database concepts from SAP HANA training) which has happened over a period of more than 30 years, with constant enhancements, research, and development. It supports the build of those applications, which are not supported by any regular RDBMS. It also helps renewal of existing applications like SAP Business Suite.

Why did SAP build a database?

With traditional data processing and ordinary database and application platform, when the large or complex data was getting too difficult to manage challenges such as analysis, capture, data curation, search, sharing, storage, transfer, visualization, querying, updating and information privacy emerged.

Believing that if a database is built with a zero response time, then the business applications would be written in a unique manner so that the IT landscapes can be simplified, SAP built a database.

SAP has been providing business applications for years. The demand for SAP training has risen. It was clear that none of the incumbent software vendors like Oracle would write such a database and application platform. That is when they decided to build their own. When SAP went to build HANA, they also realized that the next generation of business applications would require a much more integrated approach than in the past.

All SAP HANA process takes place in index server; Index Server contains Data engines to handle all SQL/MDX statements that come to HANA database system. It also has Persistence Layer that is responsible for durability of HANA system and ensures HANA system is restored to most recent state when there is a restart of system failure. Learn all the concepts related to SQL from SQL server training.

What makes SAP HANA different from other database management system (RDBMS)?

SAP HANA learning is different by design. It stores all data in-memory, in columnar format and in a compressed manner. Because HANA is fast and does not require sums, indexes materialized views and aggregates, it reduces the database footprint by 95%. Everything is calculated on-demand, as and when needed, in the main memory.  This makes it possible for companies run OLTP and analytic applications on the same instance at the same time, thus allowing any type of real-time and ad-hoc queries.

Advantages of SAP HANA

Works well with data of all sizes: Being exclusively build for complex business applications, HANA deploys data of all sizes and whilst they vary, there are a few common themes as well.

Reduction in Total Cost of Ownership (TCO): In many cases, HANA has a lower TCO. Hardware renewal costs get reduced eases valuable enterprise storage and mainframes, and the maintenance is also low.

Complex to simple:  HANA simplifies landscapes by using the same copy of a dataset for multiple applications, and adding an additional dataset to SAP HANA is quick and easy, delivering business benefits faster. SAP HANA advanced as SAP S/4HANA called as SAP 4 HANA suite learn from SAP S4 HANA training.

Differentiation: The combination of HANA’s performance, advanced analytics (Predictive, Geospatial, and Text analytics) and simplicity, offer companies for changing their business process for making it stand out from that of the competitors. Customer-oriented programs like loyalty management and personalized recommendations become easy with SAP HANA.

Risk Mitigation: Many customers know how in-memory technologies are changing the world. So they want to put an application like SAP BW on HANA (what HANA offers BW learn from SAP BW on HANA training) or LOB Datamart as a first step so that they can quickly take an action for meeting the business demands.
