Answer 1

Hi Rohith Kumar ,
To learn BW , u should know about DATA SOURCE , INFO CUBE , PSA, EXTRACT STRUCTURE , TRANSFER STRUCTURE etc.
Now my suggesstion try to learn BI ( BUSINESS INTELLIGENCE ) which is advance to BW.
The following websites contain PDF & PPT docs on BI/BW which will gain u confidence in it:
What is a BW datasource?What is meant by maintaining a datasource?
A BW datasource is a structure which is created in the source system and replicated to the BW system. Maintaining a datasource in a source system is doing any changes related to the datasource. It could be adding/deleting fields or checking the flags in the datasource like the hide and selection flag. Also, if the datasource is provided in the LO Cockpit, changes can be made there too depending on how the extraction of data is ...

Creating SAP BW data source definitions
http://publib.boulder.ibm.com/infocenter/ablxhelp/v8r4m0/index.jsp?topic=/com.ibm.db2.abx.dev.doc/abx-t-develop-sapbwdatasource.html
An InfoCube describes a self-contained dataset (from the reporting view), for example, for a business-oriented area. This dataset can be evaluated with the BEx query.An InfoCube is a set of relational tables that are created in accordance with the star schema: a large fact table in the center, with several dimension tables surrounding it.
In its esence, Infocube is a data container. Data containers are used as a basis for analysis and reporting processes in SAP BW. Infocubes in SAP BW serve exactly this purpose. Infocubes in SAP consist of Key figures and characteristics. You can find some detailed information on key figures here. Simply speaking, infocube is any repository which contains data. Moving on to the types of infocubes. In SAP BW, there are basically two classes of infocubes. These are:
Basic Infocubes - These are also called as physical infocubes.
Remote Infocubes - These are also called as virtual infocubes.
The basic difference between the above two types of infocubes is that basic infocubes are physically stored in the same SAP BW system as their meta data description. Remote infocubes are stored on a third party custom SAP BW. Both the above types of BW infocubes consist of key figures and characteristics. These characteristics in turn are divided into 16 dimensions. More on that in another post.

Extract Structure
In the extract structure, data from a DataSource is staged in the source system. The extract structure contains the amount of fields that are offered by an extractor in the source system for the data loading process. You can edit and enhance DataSource extract structures in the source system. To do this, in the BW Administrator Workbench choose Goto à Modeling à Source Systems à Your Source System à Context Menu (right mouse click) à Customizing Extractors à Subsequent Processing of DataSources.
Transfer Structure
The transfer structure is the structure in which the data is transported from the source system into the SAP Business Information Warehouse. It provides a selection of the extract structure fields for the source system.
Use
The transfer structure provides BW with all the source system information available for a business process.
An InfoSource in BW requires at least one DataSource for data extraction. DataSource data that logically belongs together is staged in an extract structure in an SAP source system.
In the transfer structure maintenance, you determine which extract structure fields are transferred to the BW. When you activate the transfer rules in BW, an identical transfer structure for BW is created in the source system from the extractor structure.
This data is transferred 1:1 from the transfer structure of the source system into the BW transfer structure, and is then transferred into the BW communication structure using the transfer rules.
A transfer structure always refers to a DataSource from a source system and an InfoSource in BW.
You get to the maintenance of the transfer structure using the InfoSource tree of the Administrator Workbench. The context menu of the source system belonging to an InfoSource provides you with the maintenance marker using the function Maintain Transfer Rules.
This website gives all definitions of Info object,infocube,infosource,datasource,commn structure,extract structure ..etc..

SAP Business Information Warehouse
SAP Business Information Warehouse (SAP BW) is the name of the Business Intelligence, analytical, reporting and Data Warehousing (DW) solution which is one of the major enterprise software applications produced by SAP AG. It was originally named SAP BIW, (Business Information Warehouse), but is now known as "SAP NetWeaver BI".
SAP BW consists among other things of components for data management (Data Warehousing Workbench), extensive data modeling capabilities, an embedded analytical engine, a suite of rich front-end analytical tools refererred to as Business Explorer (BEx), and operational tools used for importing the most current transactional data into the system. It may be helpful to consider layers that make up the structure of SAP's BI solution:
Extraction, Transformation and Load (ETL) layer - responsible for extracting data from a specific source, applying transformation rules, and loading it into SAP BW system.
Data warehouse area - responsible for storing the information in various types of structures, including multidimensional structures called InfoCubes.
Reporting - responsible for accessing the information in data warehouse area and presenting it in a user-friendly manner to the analyst or business user.
Planning - Provides capabilities for the user to run simulations and perform tasks such as budget calculations.
SAP's BI application is a very pervasively employed data warehouse / analytical enterprise software solution, often utilized heavily by companies that essentially run their business on SAP operational systems such as SAP Enterprise Resource Planning (SAP ERP, traditionally known as SAP R/3). SAP's BI solution contains a large number of predefined "extractors", a very significant amount of pre-defined business content in the form of InfoCubes, master data (i.e. objects representing the entity for "Customer", or "Material"), authorization roles, query views and reports all delivered in the software by SAP. Some of the significant benefits of this approach include the ability to leverage SAP's substantial business knowledge from many years of developing extremely sophisticated software systems for the world's largest companies, typically shortening project development cycles in the process. The pre-defined business content can be modified to meet an organization's specific requirements, while at the same time taking advantage of general aspects of these delivered data models and reports that are somewhat foundational and have broad application in business, government, and education.
SAP BW is now part of a suite of SAP applications called SAP NetWeaver. Other components of SAP NetWeaver include SAP Enterprise Portal (EP, called SAP NetWeaver Portal as of Release 7.0), Web Application Server (WAS), SAP Process Integration (PI, or previously XI, i.e. eXchange Infrastructure) and Master Data Management (MDM).
The 7.0 version of SAP BW was released in June 2006 as part of the SAP NetWeaver 7.0 (aka 2004s). This new release includes many new features, such as next-generation reporting and analytical features, major data warehousing enhancements, and possibility to use innovative techology for query performance optimization called "BI Accelerator". BI Accelerator (or BIa) comes as an external applicance, i.e. complete hardware with pre-installed software. BIa requires separate licence fee.
From SAP NetWeaver 7.0 on, the term SAP BW is obsolete, and instead it is referred simply as "SAP NetWeaver BI" - i.e. "SAP NetWeaver 7.0 BI".
According to SAP, more than 12,000 installations of SAP's BI solution exist.
SAP Business Information Warehouse (BW) is SAP´s Data Warehouse solution. It has been specially developed to allow you to gather and analyze all kinds of statistical information in the best possible way. 
The SAP Business Information Warehouse (SAP BW) is a core element of mySAP.com. SAP BW is an enterprise-wide information hub that enables data analysis from R/3 and other business application, including external data sources such as databases and the Internet. SAP BW also offers easy integration with other mySAP solutions, such as mySAP Supply Chain
Management (mySAP SCM), mySAP Strategic Enterprise Management (mySAP SEM), and mySAP Customer Relationship Management (mySAP CRM).
SAP BW is a comprehensive end-to-end data warehouse solution with optimized structures for reporting and analysis. To help knowledge workers quickly mine an enterpriseu2019s business data, SAP BW is equipped with preconfigured information models and reports, as well as automatic data extraction and loading methods. 
With an easy-to-use Microsoft Excel-based user interface, you can create, format, and analyze reports, and publish those reports to the web. Built for high performance, SAP BW resides on its own dedicated server. Online Transaction Processing (OLTP) and reporting activities are therefore separated, and system performance is not compromised.
