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.
