What is SAP HANA?

SAP HANA is a column-oriented in-memory database that combines powerful analytics with high-speed transactions in one system. What is the significance of this? Because it enables businesses to process large amounts of data with near-zero latency, query data in real time, and become genuinely data-driven. SAP HANA is unlike any other database management system (DBMS) on the market today since it stores data in column-based tables in main memory and combines online analytical processing (OLAP) with online transactional processing (OLTP). SAP HANA, which was launched in 2010, is a modern and mature system that is used by tens of thousands of clients all over the world. SAP HANA, on the other hand, is much more than a database. SAP HANA delivers extensive search, analytics, and data integration capabilities for all sorts of data – structured and unstructured – in addition to serving as a database server that stores and retrieves data requested by applications. It also serves as an application server, assisting businesses in the development of intelligent, insight-driven apps based on real-time data, in-memory computing, and machine learning. These features are available on-premises as well as in the cloud.SAP HANA simplifies IT, helps organisations innovate, and breaks down obstacles to digital transformation by merging multiple data management capabilities – and making all forms of data instantly available from a single system. SAP HANA has a variety of analytic engines for different types of data processing. A number of algorithms are included in the Corporate Function Library to solve standard business data processing algorithms such asset depreciation, rolling forecast, and moving average. Native algorithms for generating standard statistical measures in fields like clustering, classification, and time series analysis are included in the Predictive Analytics Library. Within stored procedures, HANA includes the open source statistical programming language R as a supported language.

What is an in-memory database, and how does it work?

An in-memory database (IMDB) is a database that stores data in the main memory (RAM) of a computer rather than on hard discs or solid-state drives (SSD). While most databases today have added more in-memory capabilities, they are still a disk-based storage database first. SAP HANA was built from the ground up to work with data in-memory first and leverage other storage mechanisms as necessary to balance performance and cost. Retrieval from memory is much faster than from a disk or SSD, resulting in split-second response times. A graph database can be created using a column-store database. [43] Pattern matching, neighbourhood search, single shortest path, and strongly connected components are some of the graph engine’s pre-built algorithms. Supply chain traceability, fraud detection, and logistics and route planning are all examples of typical Graph Engine applications. HANA can do text analytics and business text search in addition to numerical and statistical techniques. Like modern web-based search engines, HANA’s search capabilities is built on “fuzzy” fault-tolerant search. Search criteria might contain a threshold of accuracy for results, and results give a statistical estimate of how relevant they are.  Identifying entities such as persons, dates, places, organisations, requests, challenges, and more are among the analyses accessible. Voice of the Consumer (customer preferences and expectations), Enterprise (i.e. mergers and acquisitions, products, and organisations), and Public Sector  mergers and acquisitions, products, and organisations) can all benefit from entity extraction (public persons, events, organizations).  It’s also possible to use custom extraction and dictionaries.

Deployment

HANA can be installed on-premises or in the cloud, with a variety of cloud service providers to choose from. [50]

HANA is available as a new appliance from a certified hardware manufacturer for on-premises deployment.

Existing hardware components, like as storage and networking, can also be employed in the implementation, which SAP refers to as “Tailored Data Center Integration (TDI).” HANA is certified to run on a variety of operating systems, including Red Hat Enterprise Linux and SUSE Linux Enterprise Server. Intel 64 and POWER Systems are supported hardware platforms for on-premise deployment. 

Both horizontal and vertical scaling are supported by the system. SAP HANA is available as an Infrastructure as a Service from a number of cloud providers, including: Amazon Web Services (AWS) is a cloud computing service
