INTRODUCTION TO SAP HANA
SAP HANA is a data-oriented, relational development management system created and produced by SAP SE enterprise corporation. It is an in-memory management, data-oriented, and relational development management system. SAP HANA’s major job is to manage database applications, store, and retrieve data as needed by businesses. “High performance analytic appliances” is what SAP HANA stands for. The SAP HANA application is made up of both hardware and software components. This module is a data foundation technology that provides high-level data analytics and multi-dimensional data management for data-driven applications. The SAP HANA software is written in the Java and C programming languages.

 

SAP HANA – Core Architecture: SAP HANA [ sap hana tutorials training ]


As we all know SAP HANA, is written in the C and JAVA programming languages and is intended to work on operating systems such as LINUX server enterprise edition 11. Sap HANA is made up of a number of components that work together to conduct a variety of tasks. The Index server, which comprises of a SQL/ MDX processor to handle any type of query statement, is the most significant component of SAP HANA architecture. Name servers, statistics servers, XS engines, and preprocessor servers are all part of the SAP HANA system. All of these servers connect with one another and host a variety of web apps.
The below diagram explains the core components and work nature of the SAP HANA module:

A basic description of the index server
sap hana tutorials training
As previously stated, the index server is a critical component of the SAP HANA design. This server is also known as the SAP HANA database system’s brains. The original data and engines to process it are stored on an index server. When paired with SQL and MDX, this form of server handles the complete data request and processes it. A data engine is included in the index server to process all query statements (SQL/MDX). This also contains a persistent layer that is used to test the HANA system’s durability and restore data
In the above diagram, you can see Index server also consists of a session and transaction manager, this is used to manage transactions and keep tracking of them.

The SQL/MDX processor type is in charge of combining SQL/MDX data transactions with data engines in order to conduct various queries. It requests that all segments correct the engine in order to improve performance. This processor type handles all forms of failures as well as data authorization. MDX (multi-dimensional expression) is a query language for OLAP systems such as sequential query language and relational database management systems, sap hana tutorials training.
The planning engine is in charge of running the database’s planning activities. To develop logical data execution, the calculation engine translates the data into calculation models. To maximize data processing, the procedure call is executed by the stored processor. The persistent layer is also in charge of ensuring that SAP HANA systems are durable and atomic, as well as managing data and transaction logs for data backup, HANA system setup, and log backups.

 

Differences between SAP and SAP HANA:

Below are the major differences between SAP and SAP HANA:

 

SAP:
sap hana tutorials training
1. SAP is an ECC (Enterprise Content Management) corporate enterprise application.
2. Nearly all SAP transaction codes are available in SAP, and data simplification is not an option.
3. It makes it simple to access all of SAP’s functional modules and aids in the creation of real-time data reporting.
4. Provides increased performance, as well as updated transactions in the SAP solution.
5. Perform a database maintenance action after upgrading to ECC6 improvement package 7

 

SAP HANA:
1. Assists in the rebuilding of systems to take advantage of the SAP HANA platform’s tremendous simplification.
2. This is a packaged solution with SAP ERP at its core that has been customized for the HANA platform.
3. Assists in the integration and utilization of SAP’s numerous solutions and technologies.
4. Make data easier to understand. This is accomplished by combining the fundamental tables of various processes into a single table.
5. SAP HANA is built with SAP flori to provide a richer user experience and is easily customized using cloud technologies.

 

SAP HANA Compare to BWA (Business Warehouse Accelerator)

 

• SAP BW Accelerator: SAP BW Accelerator is an in-memory BW accelerator. BWA is working to improve SAP NetWeaver BW query performance. By maintaining copies of the infocube, BWA is specifically designed to speed up BW queries by minimizing data gathering time.

 

• SAP HANA: SAP HANA is a high-performance in-memory database and platform for analytic reports and applications. Data from SAP and non-SAP source systems can be loaded into SAP HANA using SLT, BODS, DXC, and Sybase, and viewed using SAP BO/BI, Crystal Reports, and Excel, among other tools.

SAP HANA is currently used as an in-memory database for SAP BW, allowing SAP HANA to increase the overall performance of SAP Net weaver BW.

Question and Answer

Master data management (MDM) is a comprehensive method of enabling an enterprise to link all of its critical data to one file, called a master file, that provides a common point of reference. When properly done, MDM streamlines data sharing among personnel and departments.

  • There are two types of table involved in Dimensional Modeling and this model concept is different from the third normal form. Dimensional data model concept makes use of facts table containing the measurements of the business and dimension table containing the measurement context.

A data movement mode determines how the power center server handles the character data. We choose the data movement in the Informatica server configuration settings. Two types of data movement modes available in Informatica.

It’s a matter of awareness and the problem becoming urgent. We are seeing budgets increased and greater success in closing deals, particularly in the Pharmaceutical and Financial services industries. Forrester predicts MDM will be $6 billion markets by 2010, which is a 60 percent growth rate over the $1 billion MDM market last year. Gartner forecasted that 70 percent of Global 2000 companies will have an MDM solution by the year 2010. These are pretty big numbers

We can export repository and import into the new environment
We can use Informatica deployment groups
We can Copy folders/objects
We can Export each mapping to XML and import in a new environment

It is a repository object that helps in generating, modifying or passing data. In a mapping, transformations make a representation of the operations integrated with service performs on the data. All the data goes by transformation ports that are only linked with maple or mapping.

Foreign keys of dimension tables are the primary keys of entity tables.
Foreign keys of facts tables are the primary keys of dimension tables.

A Mapplet is a reusable object that contains a set of transformations and enables to reuse that transformation logic in multiple mappings.

There are two different ways to load data in dimension tables.
Conventional (Slow) – All the constraints and keys are validated against the data before, it is loaded; this way data integrity is maintained.
Direct (Fast) – All the constraints and keys are disabled before the data is loaded. Once data is loaded, it is validated against all the constraints and keys. If data is found invalid or dirty it is not included in the index and all future processes are skipped on this data. 

Designed by Informatica Corporation, it is data integration software providing an environment that lets data loading into a centralized location like a data warehouse. From here, data can be easily extracted from an array of sources, also can be transformed as per the business logic and then can be easily loaded into files as well as relation targets.
