In 2012 SAP has a very good boom compare to 2013. Even many people are trying to learn SAP. now in SAP all modules HANA is have good openings.Technical components in HANA.
The heart of SAP HANA Enterprise 1.0 is the SAP In-Memory Database 1.0, a data store that combines massively parallel processing based online based on columns and storage techniques based objects. Other components of SAP HANA Enterprise 1.0 include:
SAP In-Memory Computing Studio
SAP Host Agent 7.2
Sybase Replication Server 15
SAP HANA Charge Controller 1.00, and
SAP Landscape Transformation 1 - CHS ABA.
SAP HANA is the introduction of SAP AG, in-memory database technology. There are five components in the Software Group
SAP HANA DB (or HANA DB) refers to the technology of the database,
SAP HANA studio refers to a set of tools provided by SAP for modeling,
SAP HANA Appliance relates to HANA DB supplied as a partner of certified equipment as a unit. It also includes tools for modeling of HANA studio, as well as replication tools and data conversion to move the data into the database HANA,
SAP HANA Application Cloud refers to a cloud infrastructure for application delivery (usually existing SAP applications rewritten to run on HANA).
HANA DB takes advantage of the low cost of memory (RAM), the data processing capabilities of multi-core processors and fast access to the data of SSDs over traditional hard disk drives to deliver the best performance of analytical and transactional applications. It features a multi-engine query environment that allows it to support both relational data (both row and column-oriented physical representation of a hybrid engine), as well as graphics and text processing for semi-and unstructured data management within a single system. HANA DB is 100% compatible ACID. With SAP HANNA you get the power to evolve in memory applications that analyze large amounts of data in real-time.
SAP HANA is the synthesis of three distinct products - TREX, P * Time and MaxDB.
TREX (Text Retrieval and extraction) is a search engine. It began in 1996 as a student project at SAP in collaboration with DFKI. TREX has become a standard feature in SAP NetWeaver 2000. Memory attributes were added in 2002 and store data column was added in 2003 as a means to improve performance.
In 2005, SAP acquired Menlo Park Transact founded in memory, Inc. With the acquisition came P * Time, light processing (OLTP) RDBMS technology memory transactions with a database based on lines .
MaxDB (formerly SAP DB), a relational database from Nixdorf via Software AG (Adabas D) SAP TREX was added to P * and time to provide persistence and functionality of more traditional data such as backup.
In 2008, SAP CTO Vishal Sikka wrote on HANA "... our teams work together with the Hasso Plattner Institute and Stanford University have shown how a new application architecture is possible, which allows for complex analyzes real-time aggregation, updated with each transaction, a way never thought possible in financial applications. " In 2009, a development initiative was launched SAP to integrate the three technologies above to provide a more complete set of features. The resulting product was named as internal and external NewDB until the change HANA DB was finalized in 2011.
SAP HANA is not the first product in memory of SAP. Business Warehouse Accelerator (BWA formerly BIA) has been designed to speed up queries by storing in memory BW InfoCubes. It was followed in 2009 by the then accelerated Explorer where the combined SAP BI Explorer tool with BWA as a tool to perform ad-hoc analyzes. Other SAP products using in-memory technology were CRM Segmentation, By Design (for analysis) and Enterprise Search (for the role of research based on structured and unstructured data). All of these were based on the TREX engine.
Taking a different approach, Advanced Planning and Optimization (APO) LiveCache used for its analysis.
Versions, service packs
Co-founder (and chairman of the supervisory board of SAP from 2012) SAP Hasso Plattner recommended system "versionless" for emissions. Support plans to date are:
SP0 - published November 20, 2010, HANA first public release
SP1 - published June 20, 2011, HANA general availability (GA), the focus is also operating a data mart
SP2 - published June 27, 2011, more functions mart data
Aka HANA 1.5 SP3 - 7 November 2011 Authorization) emphasis on HANA as a basis for the underlying data in the Business Warehouse (BW), also called Project Orange
SP4 - May 2012; solve a variety of problems of stability and to add new functionality for BW, according to SAP
SP5 - November 2012, introduced Extended Application Services driver (REST)
SP6 - June 28, 2013, current version
