HANA DATABASE

SAP HANA is an in-memory database management system developed by SAP. Its primary function as a database server is to store and retrieve data as requested by the applications. In addition, it performs advanced analytics (predictive analytics, spatial data processing, text analytics, text search, streaming analytics, graph data processing) and includes extract, transform, load (ETL) capabilities as well as an application server.

How is SAP HANA different?

"In a traditional Relational Database Management System (RDBMS), data is stored on-disk; if the RDBMS needs to access information, it must first load that data into memory, which is a relatively slow process. As an in-memory database, SAP HANA isn’t limited by the speed of the hard drive; your ERP data is already in memory, so SAP HANA can read, change or add new data almost instantly." (Gaska, 2018)

How SAP HANA works

SAP Hana stores data primarily in the form of columns which speeds up transactions and enables it to deliver instantaneous analytics. It offers better access to data with faster processing compared to traditional, row-based memory.

SAP HANA features and benefits

1.     Database services: SAP HANA benefits by combining OLAP and OLTP databases into one structure. This shrinks the database footprint, removes redundant information, changes index design, simplifies the architecture and allows businesses to analyze nearly any data on the fly (Gaska, 2018). It helps organizations take action in the moment and manage large database volumes.

2.     Advanced Analytics Processing: offers new insights from advanced analytics processing by leveraging in-memory data processing capabilities – text, predictive, spatial, graph, streaming, and time series – which helps in making smart, real-time decisions.

3.     App Development: Allows for developing next-generation applications that combine analytics and transactions, as well as deploying them on any device.

4.     Data Access: Allows organizations to gain a complete and accurate view of their businesses by accessing data from any source – internal or external. Users can access data where it’s located, integrate or replicate relevant data into SAP HANA, and ensure data quality to increase confidence in decision making.

5.     Administration: Helps organizations simplify system administration and IT operations with tools that allow them to monitor processes, ensure data and application security, and achieve continuous availability.

6.     Security: Keeps communications, data storage, and application services secure with identity and access management controls. It also offers a dashboard to monitor all KPIs related to security.
