Wednesday, 19 December 2012sap hana certification questions and answers Overview and Architecture of HANA What is HANA ? –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, 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 directly report on HANA Data from HANA can also be used in MS Excel MDX Row 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 – The data is stored in columns like in SAP BWA Persistence Layer : In memory is great but it is volatile and data can be lost with power outage or hardware failures. To avoid this HANA has a Persistence Layer component which makes sure that all the data in memory is also store in a hard drive which is not volatile. Session Management : This component takes care of logon services. Two processing engines – 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 . HANA Supports Sybase Replication Server – Sybase Replication Server can be used for real time synchronization of data between ERP and HANA Modeling Studio Using Modeling Studio you can, Specify which tables are stored in HANA, first part is to get the meta data and then schedule data replication jobs Manage Data Services to load the data from SAP BW and other 3rd party systems. Manage connections to ERP instances, current release does not support connecting to several ERP instances Use Data services to for the modeling Do modeling in HANA itself (This is independent of Data services). You can also do modeling can also be done in Business Objects Universes which is nothing but joining fact and dimensional tables. Reporting Client tools can access HANA directly, Like MS EXCEL, SAP BI 4.0 Reporting tools, Dashboard Design Tool (Xcelsius) can also access HANA directly. Third party reporting tools can leverage ODBC, JDBC and ODBO (for MDX requests) drivers in HANA for reporting. HANA supports BICS interface Request Processing and Execution Control SQL Script, MDX statements are passed to calculation models. Optimizer which is included in calculation engine optimizes for better performance. Calculation Engine : Modeler can define data sources as inputs and different operations (join, aggregation, projection) on top of them for data manipulation The calculation engine will break up a model into sub processes for optimized performance on cost based. System will use maximum resources to achieve max through put Planning Engine : Will be included in next release. Will include planning functions like distribute and copy functions. ROW Store One of the relational engines to store data in row format. Pure inmemory store (Future versions will also have an option of disk based 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 also writes to persisted segment Moves visible version from memory to persisted segment Clears outdated record versions from Transactional Version memory Row Store tables have a primary index Row ID maps to primary key Secondary indexes can be created Row ID contains the segment and the page for the record Indexes in row store only exist in memory Index definition stored with table meta virtual files Optimizer and Executer – Handles queries and execution plan Delta data for fast write Asynchronous delta merge Consistent view Manager Main store compressed and read optimized – Data is read from Main Store Delta Store – Write optimized – for write operations.Column Store Improves read functionality significantly. the columnar table will still be available for read and write operations. also improves write functionality Highly compressed data No real files. a second delta and main storage are used internally Merge operation can also be triggered manually with an SQL command Persistence Layer Persistence Layer is needed as Main memory is volatile 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 during system restart Last save point must be restored plus undo logs must be read and uncommitted transactions saved with last save point and apply redo logs Complete content of row store is loaded into memory during start process Flags can be set for column store to specify which tables are loaded during system restart Modeling Modeling only possible for Column tables . To fulfill this. Asynchronous merge move the data from delta store to main store Compression by create dictionary and applying further compression methods Even during the merge operation. SQL or MDX Information Modeler Terminology Attributes – Characteristics Measure – Key Figures Attribute Views – Dimensions Analytic Views – Cubes Calculation Views – Similar to Virtual provider concept in BW Hierarchies Leveled – based on multiple attributes . Quick Launch View at the middle and Properties view at the bottom.Information Modeler only works for column tables Replication servers create tables in column store per default Data Services creates tables in column store per default SQL to create column table: Create COLUMN TABLE Store can changed with ALTER TABLE System tables are create where they fit best Schema SYS > administrative table of engine Tables from statistics server InMemory Computing Studio Build with java based eclipse Navigator to access different HANA systems on left. 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. mass and selective load Landscapes The models are just virtual definitions they don't store actual data Analytic Views are like cube model where Transaction Data is connected to attribute view Calculation View – With custom functions and calculations Modeling Process Flow Import Source System Metadata Create Information Models Consume using BICS.. data source schemas.
