What is SAP HANA?

SAP HANA which is the acronym for SAP High-Performance Analytic Appliance is a software application that makes use of an in-memory database technology which allows for the processing of massive amounts of real-time data in a short amount of time.

The in-memory computing engine of SAP systems allows HANA to process the data that is stored in the system RAM as opposed to just reading it from a disk. This allows the application to provide an instantaneous results from customers transactions and other data analysis.

SAP HANA is developed to process highly optimized and structured data from relational database system, which includes both SAP and non-SAP based systems and applications rapidly. SAP HANA is capable of using three different styles of data replication depending on the origin of the data which are Log-based, ETL-based and trigger-based. The relocated structured data is then stored directly in the memory. Because of this, data can be accessed very fast in real time by the software applications that make use of SAP HANA.

The key differences between SAP HANA and past versions of SAP systems is that it is a column-oriented, in-memory  database system that combines both OLAP and OLTP operations into a single enterprise system,  in general, SAP HANA is an OLTAP software system.

While keeping the data in-memory offers a huge advantage in the areas of performance, it is a more costly type of data storage. Taking notes of data access patterns, with up to 85% of data in an enterprise system may be accessed infrequently, therefore it can be cost-effective to keep regularly accessed,  data in the memory while the less frequently accessed data is stored then stored on the disk, an approach SAP have named "Dynamic tiering”

Features of SAP HANA

There are many features of the SAP HANA enterprise software system, and some of them are:

1. Database Services.

2. Analytics and Data. Processing

3. Application Development and Deployment.

4. Data Access, Integration and Quality.

5. Administration and IT Operations.

6. Security.

7. Multi-Engines.

Benefits of SAP HANA

There are many benefits of the SAP HANA software, and some of them are:

1. The Power to Handle Bigger Data: With SAP HANA, your business is much better equipped to manage, handle and even go above, the Big Data trends. Not only will you be able to process a larger amount of data, but, thanks to modifications in the way the data is stored and accessed, you’ll also be able to make use of a much wider category of data.

2. Real-Time Analytic Capability: The In-memory feature of SAP HANA ensures that you’ll spend fewer time on transferring data from one location to the other. This drastically cuts down the amount of time that is needed to carry out even the most complex and comprehensive reports.

3. Scalable Solutions: No business is aiming at remaining static, therefore, one major benefits of migrating to the SAP HANA software is that, when your business needs increases and your business grows, you can easily increase the size of your SAP HANA solution.

4. Flexibility and Versatility: One of the greatest advantage of SAP HANA is that it is compatible with other databases, hardwares and softwares, thereby it one of the most broad and widely used data solutions available. This means that your team can reach greater analytic capabilities, without giving up the interfaces that they trust.
