With every passing day, newer and more advanced technology is being launched in the market. Having originated in Germany, SAP is the global leader in the Enterprise Resource Planning (ERP) sector. One of the company’s latest revolutionary technology is SAP HANA Course. 

What is SAP HANA?

SAP HANA course was launched by SAP SE in the year 2010 and since then, it has taken the world by storm. Essentially a data platform, SAP HANA is an RDBMS or a relational database management system. It can be used to implement ERP, store data and perform advanced analytical functions such a text search, predictive analysis, and processing of graphical data. The key feature of SAP HANA is that it is stored in memory rather than in optimized disks.

What is SAP HANA used for?

As a columnar database, SAP HANA has both analytical as well as transactional applications. It can be used for a plethora of functions such as advanced processing of data as well as data virtualization. Spatial processing of data, streaming analytics, and real-time insight generation from live data can be performed via SAP HANA. The data stored in the HANA database server system is extremely secure and can be accessed as per the requirement of the applications.

What is the difference between SAP and SAP HANA?

SAP is essentially a Business Suite that can run on any database. It consists of components like SAP ECC, SAP CRM, SAP SRM, SAP SCM, and SAP PLM. On the other hand, SAP HANA has been specifically developed as a relational database. The latter has the unique feature of being stored in memory. Further, SAP HANA has a column-oriented structure.

Does SAP HANA use SQL?

SQL or Structured Query Language goes hand-in-hand with all major relational database management systems. SAP HANA is no different. SQL is used as the primary database language for SAP HANA. The language can be used to create schema, select, insert, update, create, revoke, drop, grant or alter data in the SAP HANA database.

Is SAP HANA a database?

SAP HANA is an advanced database system that has a columnar structure. In particular, it is a relational database. It provides for storage of data in-memory as compared to hard disks. As a result, the data stored can be loaded on to the system and accessed at lightning speed. The SAP HANA database uses a low amount of memory and eliminates data redundancy due to its advanced architecture. 

What is the difference between SAP HANA and S 4 Hana?

While SAP HANA is the core database technology, S4 HANA is the latest ERP solution that functions only on the HANA platform. S4 HANA has been launched recently in 2019. So, S4 HANA can be considered a specialized subset of SAP HANA. S4 HANA possesses both Business Intelligence (BI) as well as ERP capabilities. It makes use of the in-memory processing power of SAP HANA for conducting all necessary analytical functions.

Key benefits of an in-memory database

Data for an in-memory database is collected in the main memory. This provides several benefits. An in-memory database offers enhanced performance speed as compared to traditional database set-ups. The system offers simple optimization algorithms and hence, results require lower response time. Data access is super-fast and query processing can be streamlined. Further, in-memory databases cut down on the count of memory transfers. This puts less pressure on the CPU and means less memory is required for data. In-memory databases are perfect for processes that require real-time data. This type of memory saves a lot of money and time required for obtaining data from the memory.

Explore SAP HANA core capabilities

SAP HANA has the ability to benefit all types of businesses. The core capabilities of SAP HANA consist of several aspects like database administration and management, application development, data security and virtualization, and multi-model processing. It provides a consolidated database for all kinds of business data. This provides a secure space for data storage and offers continuous access. Secure communication and data anonymity is provided by SAP HANA. It helps perform complex operations on different types of data with lightning speed. Intelligent and real-time operations can be performed when it comes to hybrid data. It also offers a simpler application architecture for business app development.

Is SAP HANA an ERP system?

No, SAP HANA is not an ERP system. It is an in-memory database. An Enterprise Resource Planning (ERP) system is a software widely used by all major businesses. It helps organizations to monitor and optimize business functions such as project management, accounts, supply chain management, risk management and so on. On the other side, SAP HANA acts as the core of other business functions conducted by various SAP and non-SAP software. It offers storage and fast access to business data stored within the system. For example, SAP S/4 HANA is an ERP system that operates on SAP HANA. As an ERP business suite, it can handle a company’s business function on the consolidated database offered by SAP HANA.

SAP HANA open source?

No, SAP HANA is not open source. To put simply, an open source system is one whose source code can be accessed and modified by anyone. It bears a license that allows the source code to be used by any end-user. However, SAP HANA cannot be publicly accessed or enhanced. It is an in-memory database system. It is a proprietary technology designed and produced by SAP. Although SAP has made significant contributions to the open source software market, it has chosen to not make SAP HANA an open source code. Hence, it is only available for private use, copying, modification and republishing under appropriate licensing.

Who uses SAP HANA?

SAP HANA is a market leader when it comes to Relational Database Management Systems (RDBMS). Most of SAP HANA’s customers hail from the Information Technology and Services sector. Renowned companies like Adidas, Procter & Gamble, Lenovo, Unilever, CISCO, and Walmart and known to use SAP HANA. The software witnesses maximum usage in the United States of America. Typically, SAP HANA is used in businesses who have a revenue ranging between 1 million to 10 million dollars. Companies dealing in computer systems and software can derive maximum benefits from SAP HANA. It is an in-memory database system that offers brilliant performance speed and quick data access.

How does SAP HANA work?

SAP HANA is a revolutionary storage system manufactured by SAP. It is ideal for real-time data processing and analytics. It differs significantly from a traditional database system. It can work with both SAP as well as non-SAP applications and imbibe data. The reading, processing, replicating, and ingesting of any form of data is done extremely quickly by SAP HANA. Unlike traditional database systems, the replicated data is then stored in the main memory instead of being stored in the disk storage. As a result, any hybrid data can be accessed with increased speed in the SAP HANA system. It is designed for transactional processing and real-time analytics.

Why SAP HANA is fast?

SAP HANA is an in-memory database system. It is different from the traditional database storage and management systems. Traditionally, any replicated data is stored in an allocated disk storage space. SAP HANA uses the main memory or the RAM for storing any data. Hence, when application or user requests for relevant data, it can be accessed extremely quickly. Further, SAP HANA has an advanced architecture. It uses column tables for storage instead of row tables. This provides faster retrieval of data, making the system fast. Hence, SAP HANA offers reduced loading and data accessing time. As a result, SAP HANA is perfect for applications that require real-time data access.

What is SAP HANA architecture?

Since it is an in-memory database system, SAP HANA makes use of advanced architecture. It makes use of multiple servers for its fast speed and high performance ability. The various components of a SAP HANA architecture include the Index Server, Name Server, Preprocessor Server, Statistics Server, and XS Engine. Every component contributes to the high processing and retrieving speeds of SAP HANA. The SAP HANA architecture is equipped to host and communicate with applications. The Index Server consists of the data required for processing and analysis. Multiple clients can be accommodated by the SAP HANA architecture. The architecture runs in SQLScript language.

What is SAP HANA migration?

SAP HANA helps to store your business data in-memory. It offers functionality on the cloud or on premise and offers excellent performance speed. Businesses often wish to replace their traditional database systems with a SAP HANA system. This is known as SAP HANA migration. It is a relatively complex procedure. It requires a thorough evaluation of the code architecture and appropriate customization. A sound technical migration may include a Unicode conversion as well as upgrade. Code optimized and suite migration is undertaken for a shift to SAP HANA. Extensive redesign and redevelopment of SAP HANA codes are also required to provide the perfect in-memory storage solution for a particular business.

How SAP HANA stores data?

SAP HANA has distinct differences from traditional database systems when it comes to storage of data. Although it stores relational data, SAP HANA makes use of the main memory for storage. It is a RDBMS or Relational Database Management System and aimed for real-time data processing needs. SAP HANA stores all data in-memory or in the RAM. Further, they make use of a columnar table architecture for storage of data. This is in contrast to the row-table storage followed by traditional databases. This storage option helps in faster access to data when it is needed. It optimizes reading of data and improves the performance of writing operations.

What are the benefits of using a business layer on top of SAP HANA?

SAP HANA is used by a large number businesses for better storage and access of data on cloud or on premises. An extra business layer can have a significant positive impact on the performance of the SAP HANA architecture. The additional business layer provides an extra level of granular safety and security for any business data. This ensures that any business data stored in the memory is safe from misuse. Further, the extra business layer helps the user of SAP HANA to practice flexibility with regards to the name. It allows the user to use a business name in place of a technical name.

How SAP HANA is different from other databases?

SAP HANA is distinctly different from other databases. For traditional databases, only one work process can be handled at a given point of time. However, SAP HANA can handle multiple requirement processing. Further, SAP uses the main memory for storage in contrast to the disk storage option availed by other database systems. It also used a column architecture for storage instead of the usually used row architecture. Thus, SAP HAAN helps businesses avoid the complexities of traditional databases. It does not have silos like other databases and offers a consolidate platform for reading, writing, processing, analyzing, and storing data. It can be deployed on the cloud or in premises.

What is Delta merge in SAP HANA?

Delta Merge in SAP HANA is a useful technique for optimal storage of data. It refers to the process of transferring data from a temporary Delta storage area to the main memory. A Delta storage area is responsible for collecting any and every change made to the data. This is because the Delta storage area is write-optimized. These changes then need to be shifted to the main memory. The procedure of shifting these changes to the main memory that is read-optimized is known as a Delta Merge in SAP HANA. It can be done using the technology of Smart Merge or by a manual Hard Merge.

What is the persistence layer in SAP HANA?

The Persistence Layer in SAP HANA takes care of maintaining and managing the logs for each transaction. This acts as the basic system restoration and back up function for the data. This Persistence Layer is included in the Index Server of the system. All in-memory data for every transaction is continuously saved in the volumes of this layer. Since the main memory can be extremely volatile after a power outage or restart, data can be lost. The persistence layer provides a backup for all data and can be useful in case of any loss of data. It helps in restoring the database to the latest committed state post a system failure, crash, or a restart. 

How does Delta merge in SAP HANA?

Delta Merge in SAP HANA refers to the transfer of data from the Delta storage to the Main storage. Any changes in data is moved to the Main Memory which is Read-optimized. It can be done via three methods:

  • Smart Merge
  • Hard Merge
  • Auto Merge

In Hard Merge, a manual execution is done to shift the data from the Delta Memory to the Main Memory. In Auto Merge, the shift of data from Delta to Main storage is undertaken automatically. It depends on the system’s ideal time. Smart Merge is performed by the system itself. This particular transfer takes place at the application layer.

What is column view in SAP HANA?

A column view in SAP HANA is the database visualization of any Information Model. It offers a Read-Only copy to the user. Hence, it cannot be edited. The column view is very different from the normal SQL view in any other database management system. The column view is specific to a SAP HANA system. It helps the user to generate structures similar to the view related to calculation scenarios. The modeler view of SAP HANA can also be termed as column views. They fall within any particular calculation scenario that has been allocated for them. A column view can be of three types, namely analytic view, attribute view, and calculation view.

What are calculation views in SAP HANA?

One of the most popular information views in SAP HANA is the calculation view. It is a type of column view in this database system. The calculation view can accommodate more complex calculations in contrast to the analytic view of SAP HANA. It can support a wide range of data foundation. Analytics views, calculation views, column views, and tables can be included in this. The calculation view allows us to form Unions, Joins, Projections, and Aggregations on available data sources. It supports both OLAP and OLTP models. Further, it allows for currency conversion, different languages, and client handling. A calculation view can either be graphical or script-based.

What is a transparent filter in SAP HANA?

The transparent filter is an extremely useful tool for accurate calculations in the SAP HANA database system. It is used during aggregation functions on any data source. It helps the user to avoid including unnecessary attributes during aggregation. There are certain attributes that are particularly needed for filtering while there are some that can be used for aggregation. The inclusion of the former during aggregation can lead to improper results. The transparent filter helps in preventing including filtering attributes during aggregation. Tis filter is extremely helpful for avoiding any distortions during aggregations. This filter flag was formulated and introduced with the SPS09.
