Sharing A very informative article on SAP HANA by Prashant Pimpalekar Kulkarni  All you wanted to know about SAP HANA, S/4 HANA & its roadmap:Prashant Pimpalekar

Dear friends from SAP community,
As some of you might be knowing, a LOT has been happening in the SAP world wherein two buzz words (HANA & Cloud) you can’t miss hearing! SAP Functional experts tend to have an indifferent view towards anything which is even remotely technical. But SAP S/4 HANA will sure be affecting you. SAP has launched SFIN (Simple Finance), Simple Logistics is on the anvil. And for the Cloud edition of S/4 HANA, SuccessFactors would be the default solution & not SAP-HCM! So, to get to know more details about HANA, S/4 HANA & its roadmap, you certainly don’t want to miss this article..

All you wanted to know about SAP HANA…

Historically, database systems were designed to perform well on computer systems with limited RAM. As a consequence, slow disk I/O was the main bottleneck in data throughput. The architecture of those systems was designed with a focus on optimizing disk access e.g. by minimizing the number of disk block (or pages) to be read into main memory when processing a query. Today‘s applications execute many data intense operations in the application layer, which leads to latency.

With the explosion of data all over the world (15 Petabytes of new information is created every day and expected to reach 450 billion of B2B transactions per day by 2020) & the way Information Technology is getting used by enterprise users as well as individuals (thanks to mobile phone revolution) , there is an acute need for extreme performance, low latency (response time) which in turn has led the focus on ‘In-Memory Database Platforms’.

SAP’s razor-sharp focus on in-memory database technology is paying off. SAP HANA is an in-memory,

column-oriented, relational database management system (RDBMS) that’s designed to support

transactions and complex query processing on the same data set. (Incidentally, HANA stands for High Performance Analytic Appliance. Later on, SAP is not seen keen on providing this expansion & is happy calling it just HANA, just like it did away with the expansion of SAP long ago)

SAP HANA is a full transactional, ACID (Atomicity, Consistency, Isolation, Durability) compliant relational database, designed to cost-effectively run transactions and analytics on a single copy of data, with maximum performance.

What makes SAP HANA sizzle?

  • Real Time Analytics

Thanks to in-memory architecture of SAP HANA, we can do OLTP (On Line Transaction Processing) & OLAP (On Line Analytical Processing)  at ease, enabling operational analytics. SAP HANA provides on-the-fly analysis so you can make real-time decisions. SAP HANA permits OLTP & OLAP workloads on the same platform by storing data in high-speed memory, organizing it in columns, partitioning and distributing it among multiple servers. This delivers faster queries that aggregate data more efficiently yet avoids costly full-table scans and single column indexes. There is paradigm shift for developers in HANA, since it allows all the data intensive logic down in the database as SQL, SQL script & HANA views, thereby ensuring the best application performance.

  • Massive Speed

SAP tested the scan speed of an SAP HANA database across a variety of Intel CPU processors. These tests achieved results of 3.19 billion symbol scans per second per core. The early use cases with SAP HANA address a conventional pain point by accelerating analytics, and hence insights, on massive volumes of detailed data. Hence, end users can not only get answers faster (e.g., CO-PA reports that used to take hours can now run within seconds) without disruption, but also are now empowered to ask any question without requiring additional investment of IT’s time or resources to pre-define queries, pre-aggregate data into tables or cubes, or to generate indexes and materialized views.

  • Radical Efficiency

By porting the data from a classic database to SAP HANA, eliminating unnecessary index and aggregate tables, and enabling operational reporting directly within SAP HANA, the data footprint was reduced by a factor of 37 in a test conducted and on an average 7-8 I at customer environments. With the increase in duplicate records increases the compression, reduced hardware cost and maintenance

From System R to the SAP HANA Enterprise Cloud

When SAP was founded in 1972 nobody would have known what cloud-computing would mean. One might have guessed it was related to space travel, as mankind had been visiting the moon for some years with huge rockets.

Since its beginnings SAP has helped businesses run better through world-class software solutions that solve complex problems to help invent, commercialize, and mainstream the products and services of the global economy. Today SAP is the world’s largest provider of business software. As a result of customer-inspired innovation SAP’s portfolio of solutions is currently used by more than 248,000 of the world’s best-run businesses, touches more than 74% of the world’s financial transaction revenue, and impacts more than 500 million people.

In 1972 nobody would have imagined to which extent computers would affect the lives of most people four decades later. Estimates at that time predicted only some hundred computers worldwide to exist in future. The understanding was that only large companies and governments would be able to afford such costly technology.

Today we know it turned out otherwise and since its beginnings SAP stood to benefit from the technological advance in computer science.

Real-time and Standardization

The first programs that were written from 1972 onwards emphasized the aspect of real-time. “System R” used data entry via screen and keyboard rather than punch-cards. Thus data was immediately available to support business processes and their evaluation.

The aspect of real-time was kept in focus since then whenever new software was developed by SAP.

“System R,” later called R/1, was developed on customer-owned hardware, but thanks to the ongoing miniaturization of computers the quickly growing company SAP could soon invest in its first own hardware. The next evolution of real-time software, the mainframe software SAP R/2, became a huge success during the 1980s. It supported not only instant availability of data but provided an integrated view of all relevant business areas.

A second important attribute of SAP’s software is standardization. Standard software addresses many customers’ needs with a basically identically coding using a standard set of customizing options. This has many benefits: software development can be streamlined, upgrades can be better planned, customer support can be more efficient and it facilitates forming a stable network of partners.

Evolution

Keeping the core features of real-time and standardization SAP profited from the newly emerged personal computers and invented a client-server version of its established SAP R/2: SAP R/3 which was released in 1992 and became not only an even bigger success but an industry standard in its own.

SAP enhanced SAP R/3 with various standard industry variations and closely attached additional software packages until SAP R/3 was incorporated in the SAP ERP Business Suite in 2004.

With real-time enabled standard software SAP was also entering the next steps in software evolution: mobile, big data and cloud.

  • Big data requires efficient ways to deal with data volumes, SAP’s answer to this is its home bred in-memory computing: SAP HANA. SAP HANA will become an integral part of SAP ERP.
  • For the cloud market SAP developed a comprehensive portfolio of various line-of-business solutions and a cloud-ERP (Business ByDesign) and acquired important cloud-players like SuccessFactors and Ariba.

Revolution

“HANA redefines the market for enterprise software – it’s only logical to take it to the cloud,”

said Hasso Plattner during the announcement of SAP HANA Enterprise Cloud (HEC) in May 2013. The goal is combining the power of real time with the simplicity of the cloud while leveraging SAP’s 40 years of application experience with mission critical data centers. HEC will make in-memory computing quickly available for a large customer base in a managed cloud environment that includes a wide range of flexible options.
