BW OverviewThe Business Warehouse (BW) is SAPs architectural solution for data warehousingBW is a separate system from the R/3 transaction processing systemBW data structures are optimized for reporting data efficiently and quickly (analytical processing)

Excel functionality can be utilized (calculations, charts, VBA programming, etc.)

Queries are refreshed at each run; workbooks provide pre-calculated queries

Incorporates BW Security and, therefore, eliminates the need for an additional layer of security at the reporting level

What is Business Content?Advantages of using Business ContentPre-Configured SAP-delivered objects allow rapid development (DataSources, Transfer Structures, ODSs, InfoCubes, Queries, etc.)Based on Best Practices

A solution to build uponProvides a good baseline for enhancements of functionality and data models.

Web AS (SAP Web Application Server)Based in 3 tier architectureDevelopment and runtime time environmentCame into picture after 2004 (SAP Net Weaver)Have all functions of typical application server in addition to load balancingFrom ECC 6.4 onwards, it had two components : Web AS ABAP and Web as JAVAWith ECC 6.4, SAP BW 3.5 was releasedWeb AS ABAP and Web AS JAVA can run in isolation (self-contained) and on different hardware.Both of these have different database and database schema

Vandana GoyalWeb AS ABAP Runs on ABAP WorkbenchActual SAP BW platformUses file interface to communicate with heterogeneous systems and BAPIs( Business Application Programming Interface) with SAP systemsIn SAP BW 3.5, Web AS ABAP was mandatory while Web AS JAVA was optional Dialects through Open SQL ABAP

Vandana GoyalWeb AS JavaIt has JAVA Database Dictionary / Workbench Runs on J2EE Engine platformDialects through Open SQL JAVASAP Enterprise Portal, SAP Mobile Infrastructure, SAP Exchange Infrastructure (SAP XI) and Knowledge Management are developed on Web AS JAVAMandatory for information broadcasting and ad-hoc reportingVandana GoyalFile InterfaceUsed to exchange data with non-system systemPrior to release 3 of SAP R/3 system, file interfaces were only usedVandana GoyalBAPIs Series of interfacesSAP systems as well as Third Party systems uses to access SAP systemsBased on RFCs(Remote Function Calls)Data is transferred via TCP/IP as byte flowRFC Transaction Code: SM59RFCs can be synchronous or asynchronousSynchronous RFCs also called as transactional RFC (TRFC)Vandana GoyalALE / IDocsALE (Application Link Enabling) is a data transfer tool or toolkitSupports both synchronous and asynchronous connectionRequires little programmingData is transferred via IDocs (Intermediate documents)IDocs were used in earlier versions, have unfavorable performance point viewHave been replace by RFCs

Vandana GoyalInternet Communication Framework( ICF)Enables communication via HTTP, HTTPS and SMTP protocolsUsed by both Web as JAVA and Web as ABAPBW can be a client and send requests to web servers for data extractionsBW can be a server and pass on data to web services (e.g. Web Analyzer)
