SAP is an in-memory database engine SAP that is used to analyze large data sets in real-time that reside entirely in memory.
Storing data of a database in main memory (RAM) rather than on a Hard Disk. It is very faster than a hard disk.
It means It stores data in the main memory (RAM) of the system, so it becomes very much faster than any conventional database.
What is an in-memory database in SAP HANA?
The meaning of In-Memory database in SAP HANA is data from a source system is stored in a RAM but in a conventional Database system, all data is stored in the hard disk of the system.
In this fashion (In-Memory Database) of SAP HANA do not waste time in loading the data to the RAM from the Hard Disk.
SAP HANA supports multicore CPUs for faster processing and analysis of information.
SAP HANA Benefits:
Best Gaming Laptop Under 1 Lakh
There are the following advantages of SAP HANA.
- It supports multi-core CPU Architecture that uses parallel processing
- This database is 1 Million times faster than a conventional database system.
- It stores data in a Row-based and Column based fashion in the Database system.
- SAP HANA is called a hybrid In-memory database system.
- Assume, In a conventional database system, data reading takes 5 milliseconds for a certain amount of data. That same data will be read from the SAP HANA database in very less time than 5 Nanoseconds. That is amazing.
- Because of Multi-core CPUs, The task can be distributed by the HANA system to multiple CPUs in a distributed environment.

What is SAP S/4 HANA?
SAP S/4 HANA is a next-generation business suite designed by SAP AG and runs only on SAP HANA it is launched in February 2015.
S/4 HANA stands for SAP Business Suite 4 SAP HANA. SAP S/4 HANA is the 4th generation business suite version of SAP.
The difference between SAP HANA and SAP S/4 HANA is –
SAP HANA is a Backend database system of SAP and SAP S/4 HANA is a front-end system of SAP. Sap S/4 HANA can be run only on the SAP HANA database.
SAP HANA Studio
This is a combination of applications for SAP HANA. It provides technical users to manage the SAP HANA database system, to create and manage user’s authorizations.
The SAP HANA studio runs on the Eclipse platform.
It is mainly an Eclipse-based tool. This studio provides both the central development environment and as well as the main administration tool for the HANA system.
This is a client tool. It can be used to access remote HANA systems or Local Systems.
SAP HANA Studio provides an environment for the following features
HANA Administration
HANA Information Modeling
Data Provisioning in the HANA database
What is SAP HANA cockpit?
This is an administrative tool of SAP ERP, Which is used to manage SAP HANA backup, Security issues, and overall performance actions. SAP HANA Cockpit tool is a web interface for the SAP database engine. This Cockpit allows both cloud operations and offline for managing databases.
SAP HANA Architecture
There are the following techniques for data compression.
Example:
Dictionary Encoding
Run-length encoding
Sparse encoding
Cluster encoding
Indirect encoding for Column store.
When the main memory of SAP HANA limit is reached, then whole database objects like table, view and programs that are not used will be saved back into the Hard Disk from the main memory.
And again it will be reloaded into the main memory from the Hard Disk when it is required.
In this situation, the SAP HANA database manages all unloading and loading activities of data automatically.
SAP HANA Architecture:
Index Server
Preprocessor Server
Name Server
Statistics Server
XS Engine

SAP HANA Views
There are the following types of SAP HANA Views
- Attribute views: It provides descriptive characteristics of data in the SAP HANA database. Attribute view is a Master data that defines relationships between data elements.
- Analytic views: It is used to aggregate mass data. This view constructs a central master table known as the “Fact Table” with the key. Here we can use operators, expressions, and functions to analyze the data.
- Calculation views: It provides flexibility for complex logic in the database. It is built on top of analytic or attribute views and It allows us to do calculations after aggregation and grouping. Generally, calculations are done after grouping at the attribute level.
SAP HANA Vora
SAP HANA Vora is an in-memory computing engine that’s designed to form big data from Hadoop more accessible and usable for enterprises.
SAP developed Vora out of SAP HANA as how to deal with specific business cases involving big data.
Hadoop offers lower-cost storage for vast amounts of information, but adoption initially lagged within the enterprise because the info during a data lake is unstructured and may be hard to deal with.
SAP HANA Vora builds structured data hierarchies for the Hadoop data and integrates it with data from HANA to enable OLAP-style in-memory analysis on the combined data through an Apache Spark structured query language (SQL) interface.

Real-Time SAP HANA Interview Questions and Answers for 2020
1. What is the meaning of in-memory computing? What is its significance?
Ans. within in-memory computing, an enormous amount of knowledge as the information is stored within the Random-Access Memory (RAM) instead of auxiliary storage disks.
This technology replaces the traditional way of storing data in disks and uses relational database management methods to fetch and process the data.
In-memory computing technology is far cheaper and faster than the normal database system. SAP HANA keeps a primary copy of the information ready in in-memory storage which results in data access and processing for ad-hoc reporting, analysis of knowledge in real-time, and quick query response.
Also, it reduces data complexity, data redundancy, data footprint, hardware and IT costs.
2. What is the meaning of SAP HANA?
Ans. This is an in-memory database that encompasses special software and hardware components used for a centralized ERP system and business application development.
It uses a real-time processing engine which fetches data directly from the in-memory (main memory/RAM) speeding up the info retrieval operations.
3. Why is SAP HANA unique?
Ans. SAP HANA proves to be a singular tool for users in some ways.
The reasons for uniqueness are:
It is the first technology ever to be used for both OLTP and OLAP application processing.
It provides a query processing environment for structured as well as unstructured data. That is, for both relational databases (tables) and less structured (texts, graphs) respectively.
The multi-core processing engines of the SAP HANA system process data parallelly. The multiprocessing is completed within different columns of an equivalent database. Using a columnar database, the system optimizes data structure and eases storing large data by compressing it.
Explore the core features of SAP HANA that make it unique
