What does SAP HANA Means?

SAP HANA stands for High-Performance Analytic Appliance. It is an application that uses in-memory database technology which allows the processing of massive amounts of real-time data in a short time. The in-memory computing engine allows HANA to process data stored in RAM as compared to reading it from a hard disk. This allows the application to provide immediate results from customer transactions and data analyses without any processing delay.

SAP HANA is designed to process structured data from relational databases, both SAP and non-SAP, and applications and other systems rapidly. The relocated structured data is stored directly in memory. Because of this, data can be accessed quickly in real time by the applications that use HANA.

What does In-Memory Database (IMDB) mean?

An in-memory database (IMDB) is a database management system that primarily depends on main memory for storing computer data. IMDBs are quicker than disk-optimized databases because they carry out fewer CPU instructions, and their internal optimization algorithms are much simpler.

IMDBs are mainly used in applications where response time is crucial, such as telecommunications network devices and mobile ad networks. An in-memory database also may be known as a main memory database (MMDB), real-time database (RTDB) or in-memory database system (IMDS).

The advantages of IMDBs are as follows:

• Faster transactions
• No translation
• Multi-user concurrency
• High stability

What does In-Memory Computing mean?

In-memory computing is the storage of information in the main random access memory (RAM) of dedicated servers rather than in complicated relational databases operating on comparatively slow disk drives. In-memory computing helps business customers, including retailers, banks and utilities, to quickly detect patterns, analyze massive data volumes on the fly, and perform their operations quickly.

Some of the advantages of in-memory computing include:

• The ability to cache countless amounts of data constantly. This ensures extremely fast response times for searches.
• The ability to store session data, allowing for the customization of live sessions and ensuring optimum website performance.
• The ability to process events for improved complex event processing
