Big data refers to data sets that exceed the capabilities of commonly used tools. Although no formal definition is based on the size, these datasets generally reach terabytes (TB), petabytes (PB), or exabytes. SAP HANA is positioned as a solution to the major challenges of data at the bottom of this scale. When launched HANA started with 1TB of RAM supports up to 5 TB of uncompressed data. Late 2011 hardware with 8 TB of RAM which became available supported up to 40 TB of uncompressed data. SAP Sybase IQ owned by its more mature MapReduce-like functionality has been cited as potentially better fit for large data sets. In May 2012 HANA was able to run on servers with main memory 100 TB powered by IBM. Hasso Plattner said the system was large enough to carry eight largest SAP customers.
Strategic workforce planning
SAP Business Objects Strategic Workforce Planning (SWP) was among the first SAP application to be redesigned to take advantage of the capabilities of Hana. SWP HANA is for HR executives who want to simulate models of labor taking into account real-time turnover, retirement, employment and other variables.
Analytics smart meters
In September 2011, SAP released its analysis tool smart meters. This is to help utilities with large deployments of smart meters to manage and utilize the large amount of data generated by these counters.
SAP HANA Cloud options
In September 2011, SAP announced its intention to work in partnership with EMC and VM ware to enable a cloud application infrastructure based on HANA. This platform as a service offering (PaaS) includes HANA DB-as-a-service in collaboration with the choice between a Java or ABAP stack based. Applications created for each cell will have access to HANA DB through a variety of APIs. The approach based on Java, the code name Project of the river, is based on the 7.3.1 server Net Weaver Java applications. ABAP-based approach is designed more for the existing user base of SAP - for example, SAP Business By Design Business Suite of enterprise applications, including ERP, CRM and management of the supply chain.
On October 16, 2012 SAP announced the general availability of two options SAP HANA delivered in the cloud
SAP Net Weaver Cloud (now called SAP HANA Cloud - an application service based on open standards and
One SAP HANA - the deployment of SAP HANA on the Amazon Web Services cloud on an hourly basis. 60GB is the only option available and costs a 24/7 of $ 30,572 / year instance, but an initial engagement with Amazon can significantly reduce the hardware cost.
As it is very central, the SAP HANA DB is "just" a relational database. There are a lot more, but before you dive into the details, make sure you know your SQL. So make sure you have the SQL 92 specification available, and if necessary, find a tutorial on SQL Web - or let me Google for you.
Advanced programming HANA
I mentioned earlier that HANA is "much more than a relational database" - look at some of the more
Did you know that HANA supports full-text search and can therefore bridge the gap between what is commonly called the data (text only) "structured" (tables with fields that you usually find in relational databases) and " unstructured "? Research of Fuzzy Developer's Guide provides information on how to - well, the title says it all - how fuzzy searches on text data
One of the most interesting features of Hana is the integration of statistical functions (the so-called Library Predictive Analytics - PAL) and business functions (Business Function Library - BFL) in the core database. Discover Predictive Analysis Manual Library-reference manual library business functions.
I pointed out this section, as in my humble opinion, this is the coolest part of SAP HANA. HANA create potential as a basis for high-speed data - but these libraries are a great example for SAP HANA is a database.
Except for writing wrappers around PAL / BFL, do not worry too much about the L-language at this point. It will most likely suffer a significant simplification rolled before a wider public developers (if applicable). Future versions call PAL / BFL will probably not even need those wrapper more, but be integrated more naturally SQL Script.
In case the PAL does not provide the statistical analysis function you want to perform on the data - you can be sure of Statistics popular programming language R will. So if you're really in mathematics, see HANA R-integration. For licensing reasons, we can not group R with HANA, but it is very easy to install - the HANA documentation is a guide for it, and my colleague Blag wrote a blog to get started easily.
