INTRODUCTION:
1. HANA stands for high-performance analytic appliance.
2 .SAP HANA is an application that uses in-memory database technology that allows the processing of massive amounts of real-time data in a short time. The in-memory computing engine allows HANA to process data stored in RAM as opposed to reading it from a disk. This allows the application to provide instantaneous results from customer transactions and data analyses.
3 .SAP HANA is designed to process structured data from relational databases, both SAP and non-SAP, and applications and other systems rapidly. It is capable of using three styles of data replication depending on the source of the data - log-based, ETL-based and trigger-based. The relocated structured data is stored directly in memory. Because of this, data can be accessed quickly in real time by the applications that use HANA.
4. SAP HANA supports various use cases for real-time analytics.
ARCHITECHTURE OVERVIEW (SAP HANA DATABASE AND SURROUNDINGS):
REPORTING ON SAP HANA WITH BI 4.0 (CLIENT AND CONNECTIVITY OPTIONS):
REPORTING ON SAP HANA – OPEN INTERFACES:
HANA 1.0 provides various interface reporting options
ODBO – OLE DB for OLAP: Microsoft-driven specification for multidimensional (cross-tab style) reporting Requests are sent to the database via MDX (Multi Dimensional expression language)
ODBC – Open Database Connectivity: Microsoft-driven specification for relational reporting Database requests are made via SQL (Structured Query Language)
Heavily adopted in industry No longer Microsoft-centric - Unix and Linux drivers exist for ODBC
JDBC – Java Database Connectivity: Relational reporting drivers specified by the Java community. Popular on Unix platforms
BICS – BI Consumer Services: SAP Proprietary interface that offers advantages for OLAP access over MDX on multidimensional reporting objects
Common driver technology used by SAP BusinessObjects Analysis, Office Edition (v 1.2) and Semantic Layer based BOBJ BI clients for connectivity to SAP Netweaver BW
SQLDBC is SAP native database SDK
WHY SAP HANA:
Why wait for data: All customers want to see their current business data immediately in real-time. Nobody wants to wait until data is uploaded into BW.
Why wait for new systems: Latest hardware and latest database technology already now support real-time reporting on massive amount of data.
