HANA Architecture?

The SAP HANA database is developed in C++ and runs on SUSE Linux Server. SAP HANA database consists of multiple servers and the most important component is the Index Server and consists of the following.

Index Server: Main component of DB and contains data stores, and engine for processing the data. Process the queries in authenticated session and transactions.

Persistence Layer: Responsible for durability and atomicity of transactions. Make sure that data is committed and can be restore in case of disasters.

Processor Server: The index server uses the preprocessor server for analyzing text data and extracting the information on which the text search capabilities are based.

Name Server: The name server owns the information about system. In a distributed system, the name server knows location of components running and data located on which server.

XS Engine: Uses HTTP module (engine) to connect to HANA database.

What is row store and column store in HANA?

Row Storage: It stores table records in a sequence of rows. Oracle, SQL server, Teradata store data in row storage.

Column Storage: It stores table records in a sequence of columns i.e. the entries of a column is stored in contiguous memory locations.

What is calculation view, analytical view and attribute view?

Attribute View: Attribute view(s) are dimensions or master data and can be joined with dimension table or another attribute view.

Analytic View: Consists of fact table (master table) with various dimension tables. Fact table contains the transnational information. Easy to summarize (aggregate) the data from dimensions table.

Calculation View: Calculation views are composite views and can perform complex calculation on data. It can combine information(such as facts) from various table, attribute and analytical views into one large chunk.

SAP HANA Overview | SAP HANA Introduction | Why SAP HANA is Growing

SAP HANA , short for “ H igh-Performance An alytic A ppliance” is an in-memory; column-oriented, relational database management system developed by SAP. Data now resides in main-memory (RAM) and no longer on a hard disk. It is a combination of hardware and software made to process massive real time data using In-Memory computing. It combines row-based, column-based database technology . It’s best suited for performing real-time analytics on massive data , and developing & deploying real-time applications. An in-memory database means all the data is stored in the memory (RAM). No time wasted in loading the data from hard-disk to RAM or storing the data in hard-disk. Everything is stored inside memory for all the time, which gives quick access ability to the CPUs while processing data. The SAP HANA database is developed in C++ and runs on SUSE Linux Server. SAP HANA database consists of multiple servers and the most important component is the Index Server which c...
