Overview and Architecture of HANA What is HANA ? –High ? –High Performance Analytical Appliance - In memory computing engine In memory computing studio as a frontend for modeling and administration. HANA is connected to ERP systems, ERP systems, Frontend modeling studio can be used for load control and replication server management Two types of Relational Data stores in HANA : Row Store, Column Store SAP BOBJ tools can tools can directly report on HANA Data from HANA can also be used be used in MS MS Excel - MDX Row Store – Store – Traditional Relational Database. The difference is that all the rows are in memory in HANA where as they are stored in a hard drive in traditional databases. Column Store – Store – The data is stored in columns like in SAP BWA : In memory is great but it is volatile and data can be lost with Persistence La yer : Persistence power outage or hardware failures. To avoid this HANA has a Persistence Layer

which is not volatile. Session Management : This component takes care of logon services. Two processing processing e ngines ngines – – Well, data is in memory which is good but How do I extract/report on the data? HANA has two processing engines one is based on SQL which accepts SQL queries and the other one is based on MDX . MDX . HANA Supports Sybase Replication Server – Sybase Replication Server can be used for real time synchronization of data between ERP and HANA

Request Processing and Execution Control SQL Script, Script, MDX MDX statements statements are pa ssed to calculation models. Optimizer Opt imizer which is included in calculation engine optimi zes for better performance. Calculation Engine : Modeler can define data sources as inputs and different operations join, join ( , aggregation, projection) on top of them for data manipulation The calculation engine will break up a model into sub processe s for optimized performance on cost based. System Sy stem will use m aximum resources to achieve max through through put Planning Engine : Will : Will be included in next release. Will include planning functions like distribute and copy functions.
ROW Store One of the relational engines to s tore data in row format. Pure in-memory store (Future (Future versions versions will als o have an option of disk bas ed store) In memory object store (in future) for live cache functionality Transactions Version Memory is the heart of row store Row store architecture Write operation mainly go into "Transactional Version Memory" INSERT INSE RT also writes to persisted s egment Mov oves es visible version from memory to persisted segment Clears outdated record versions versions from Transactional Version Version m emory Row Store tables have a primar y index index

Secondary indexes can be created Row ID contains the segm ent and the page for the record Indexes in row store only exist in mem ory Index definition stored with table meta
Column Store Improves read functionality significantly, als o improves write functionality Highly compress ed data No real files , virtual files Optimizer and Executer – Handles queries and execution plan Delta data for fast write Asynchrono us de lta merge Consistent view Manager Main store compress ed and read optimized – Data is read from Main Store Delta Store – Write optimized – for write operations. Asynchronous mer ge move the data from delta store to ma in store Compress ion by create dictionary and applying further compression methods Even during the m erge operation, the columnar table will s till be available for read and write operations. To fulfill this, a second del ta and main s torage are used internally Merge operation can also be triggered manually with an SQL command
Persistence Layer
Provides Backup and Restore functionality One Persistency Layer takes care of both row and column stores Regular Save Points Logs capturing DB transactions since last save point
Actions d uring s ystem restart Last save point must be restored plus undo logs mus t be read and uncommitted transactions saved with last save point and apply redo logs Complete content of row store is loade d into mem ory during start process Flags can be s et for column store to specify which tables are loaded during system restart
Modeling Modeling only possible for Column tables Information Modeler only works for colum n tables Replication servers create tables in column store per default Data Services creates tables i n column s tore per default SQL to create column table: Create COLUMN TABLE Store can chan ged wi th ALTER TABLE System tables are create where they fit best Schema SYS -> adminis trative table of engine Tables from s tatistics server
In-Memory Computing Studio Build with java based e clipse Navigator to access different HANA systems on left, Quick Launch View at the middle and Properties view at the bottom. Information Modeler Features: Database views Choice to publish and consume at 4 levels of modeling Attribute view, analytic view ... Physical tables and Information Models Import/export models, data s ource schemas , mass and sel ective load Landscapes The models are just virtual definitions they don't store actual data Analytic Views are like cube m odel wh ere Transa ction Data is con nected to attribute view Calculation View – With custom functions and calculations Modeling Process Flow Import Source System Metadata Create Information Models Consume using BICS, SQL or MDX Information Modeler Terminology Attributes – Ch aracteris tics Measure – Key Figures Attribute Views – Dim ens ions Analytic Views – Cubes
Hierarchies Leveled – based on multiple attributes Parent-child hierarchy Analytic Privilege – Security Object
Navigation View HANA instance -> Hana server name a nd instance num ber -> user database schema -> views functions and tables Information Models – Attribute, Analytic, Calculation Views and Analytic Privilege
Attribute View : Attributes a dd context to data Attributes a re mode led us ing attributes views Can be regarded as Master Data Tables Can be linked to fact tables in Analytical Views A mea sure e.g. wei ght can be define d as an a ttributes Table Joins and properties Left outer, right outer, full outer or text table Cardinality 1:1, N:1, 1:N Language Column Analytic View: Similar to Cube Analytic Views does not store any data. The data is s tored in colum n store tabl e or view based on Analytical View structure
Attributes a nd Measures – Like key figures Data Preview – Similar to lis t cube functionality
Calculation View : Define table output Structure Write SQL statement Ensure the sele cted fields corresponds to previously defined output structures SQL Scripts unlike SQL procedure can't change any data they are read only
Other Notes: External tools can connect to HANA using JDBC and ODBC drivers HANA currently doesn't support complete MDX set, it supports EXCEL 2010 standard MDX BWA Hardware can be upgraded to HANA given that hardware is relatively new BWA Licenses can be transferred to HANA ERP and BW can be connected to HANA using Data services or Sybase Replication No name s pace concept in HANA at this m oment, so two ERP instances can't be connected to HANA.

SAP BW implemented on HANA SP1.3, what are the stes need to be done? a. Migrate the BW data into HANA b. Create In-memory Indexes c. Convert Info cubes into HANA object types. d. ??? 2. Backup and recovery by SAP standard? a. point-in-time recovery b. backi ng up of archived log files c. information model recovery d. 3.History => keeps track of object changes usi ng the versions.??? 4. hich user hasor the analytic view: table, attribute view
