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
