Introduction to SAP HANA
SAP HANA is a flexible, data-source-agnostic appliance that enables
customers to analyze large volumes of SAP ERP data in real-time, avoiding the need to materialize transformations.
In-memory databaseIt supports analytical and transactional applications.It supports relational data as well as graph and text
processing for semi- and unstructured data It is “ACID” compliant.

SAP HANA--- The Time is NOW SAP HANA--- The Time is NOW Orchestrating Orchestrating Technology InnovationsTechnology Innovations
HW Technology Innovations
64bit address space – 2TB in current servers
100GB/s data throughput
Dramatic decline in price/performance
Multi-Core Architecture (8 x 8core CPU per blade)
Massive parallel scaling with many blades
Row and Column Store
Compression
Partitioning
No Aggregate Tables
Real-Time Data Capture
Insert Only on Delta
The elements of In-Memory computing are not new. However, dramatically improved hardware economics and technology innovations in software has now made it possible for SAP to deliver on its vision of the Real-Time Enterprise with In-Memory business applications
SAP SW Technology Innovations

Processors are more powerful with hyper threading and higher clocking speeds thus offer higher throughputAlso processors come with multiple processing units ( multi cores)Multi CPU Boards per serverMulti server boards
For ex: Nahelms – 4 cores Dunnington – 6 cores

A partition is a division of a logical database or its constituting elements into distinct independent parts
Horizontal partitioning Vertical partitioning

Columnar database allows basic data compression by removing redundant data.
Run-length encoding
Also, there are several other compression algorithms with which data can be lossless compressed..Eg: dictionary encoding, bit vector encoding

SAP HANASupports any data sources.Supports transactional and analytical processing.Supports row-store and column store.It’s a faster RDBMS.
SAP BIA/BWASupports only data from BI for faster reporting purposes.Not an RDBMS.Supports only column store using TREX flat files.
