What is SAP HANA?
What is SAP HANA?
SAP HANA (High-performance ANalytic Appliance) is a multi-model database that stores data in its memory instead of keeping it on a disk. The column-oriented in-memory database design allows you to run advanced analytics alongside high-speed transactions – in a single system. Why is this so important? Because it lets companies process massive amounts of data with near-zero latency, query data in an instant, and become truly data-driven. By storing data in column-based tables in main memory and bringing online analytical processing (OLAP) and online transactional processing (OLTP) together, SAP HANA is unique – and significantly faster than other database management systems (DBMS) on the market today.
Launched in 2010, SAP HANA is a modern and mature solution used by tens of thousands of customers around the world. But SAP HANA is much more than a database. In addition to acting as a database server, storing and retrieving data requested by applications, SAP HANA offers advanced search, analytics, and data integration capabilities for all types of data – structured and unstructured. It also functions as an application server and helps companies build smart, insight-driven applications based on real-time data, in-memory computing, and machine learning technology. These capabilities are available both in the cloud, and on-premise.
By combining multiple data management capabilities – and making all types of data instantly available from a single system – SAP HANA simplifies IT, helps businesses innovate, and knocks down barriers to digital transformation.
What is an in-memory database?
An in-memory database (IMDB) is a type of database that stores data in a computer’s main memory (RAM) instead of on traditional disks 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.
In-memory databases are often used for applications that require top speed and the ability to handle large spikes in traffic – such as telecommunications networks and banking systems. In the last 10 years or so, mainly due to advancements in multi-core processors and less expensive RAM, companies have started to use in-memory databases for a wider range of applications, including real-time analytics and predictive modelling, customer experience management, logistics, and much more.

SAP HANA architecture
Built for fast queries and high-speed transactions – SAP HANA’s in-memory, column-oriented architecture also includes, database management, application development, advanced analytical processing, and flexible data virtualisation.
- In-memory, columnar, massively parallel processing database: SAP HANA runs transactional and analytical workloads using a single instance of the data on a single platform. It stores data in high-speed memory, organises it in columns, and partitions and distributes it among multiple servers. This delivers faster queries more efficiently than aggregate data and avoids costly full-table scans.
- ACID compliance: Helps ensure compliance with all requirements for Atomicity, Consistency, Isolation, and Durability (ACID) standards.
- Multi-tenancy: Allows multiple tenant databases to run in one system, sharing the same memory and processors. Each tenant database is fully isolated with its own database users, catalog, repository, data files, and log files for maximum security and control.
- Multi-tier storage and persistent memory support: Various software solutions manage multi-temperature data (hot, warm, and cold) to optimise performance and cost of storage. SAP HANA’s native storage extension is a built-in capability to intelligently manage data between memory and persistent storage such as the SAP HANA Cloud Data Lake. Learn more about SAP HANA persistent memory.
- Scaling: Supports terabytes of data in a single server and scales further by implementing a shared-nothing architecture across multiple servers in a cluster. Distributes large tables across these servers automatically based on rules.
- Data modelling: SAP HANA’s in memory technology has enabled application developers/modelers to rethink traditional modelling using a virtual data model. Graphical modelling tools enable easy collaboration between stakeholders and creation of models to execute complex business logic and data transformation that can be processed in real-time.
- Stored procedures: SAP HANA has a native language to build stored procedures and uses advanced capabilities to create complex logic that runs inside the database.
- Administration: Provides comprehensive administration tools for various platform lifecycle, performance, and management operations and automation, such as start, stop, restart, back up, and recover.
- Security: Unique real-time data anonymization capabilities to extract value from data while protecting privacy. Robust authentication, user management, and authorisation protocols help ensure that users access only the data they have permission to see and handle. Learn more about SAP HANA security.
- High availability and disaster recovery: SAP HANA supports high availability and disaster recovery to meet a broad range of service levels through an array of techniques – such as backup, storage mirroring, synchronous, asynchronous, and multitarget system replication, hot standby, auto restart, and auto failover.

How do you migrate from a traditional database to an in-memory and column-oriented database?
How you manage with SAP HANA is much different than in legacy databases and most implementations will result in a smaller data footprint. Dedicate time to research the technology, explore success stories, read the blogs, and develop a list of implementation resources. Here are the steps for migrating to SAP HANA:
Legacy systems always have some outdated applications, custom code, and data that must be addressed in the migration planning.
On-premises, cloud, or hybrid are all viable with SAP HANA.
Determine the amount of memory your main data set will require. Plan the memory size for static and dynamic data as well as the disk size requirements for “persistent storage.”
This is a wonderful opportunity to remove bad, duplicate, and old data to streamline your systems and reduce your data footprint.
Well ahead of your go-live date, perform a proof of concept to validate the migration process and collect feedback on what worked and what needs to be changed.

SAP HANA frequently asked questions
A database management system (DBMS) is software/services used for the storage and organisation of data that traditionally has defined structures or formats. There are different types of DBMS systems typically classified by the type(s) of data they manage (structured data, non-structured data, etc,). A traditional ERP maintains relationships between data items, storing their basic definition and characteristics and enable data consumers to query or access information as needed.
A columnar database stores groups of related information together in columns rather than in rows. This allows for much faster queries and analysis of similar data than when using a row-based system. These databases are very common in in-memory business applications and in data warehouses where faster retrieval speed is important. The format is traditionally well suited for analytics. A columnar database reduces the amount of resources needed for queries made on related sets of data.
OLAP online analytical processing describes systems and software that are optimised for processing large amounts of data primarily for analytical purposes. This type of processing also supports complex calculations, modelling, and data mining, making it ideal for decision support and executive reporting functions.
OLTP (online transactional processing) is a computing approach that is optimised for interactive tasks that require quick response – transaction processing for point-of-sale terminals or booking reservations, for example. These tasks entail a lot of input/output interaction with users expecting instant response. OLTP does not concern itself with massive data stores beyond what is needed for the task at hand and does not involve complex computing, both of which are the domain of OLAP.
Yes. SAP HANA is a column-oriented, in-memory relational database that combines OLAP and OLTP operations into a single system. It needs less disk space than some of its competitors and is highly scalable. SAP HANA is deployable on premises, in a public or private cloud, and in hybrid scenarios. This database is suited for advanced analytical and transactional work with a variety of data types. In addition to database management, SAP HANA offers advanced analytical processing, data integration, and application development.
