SAP BO 4.1 INTERIVIEW QUESTIONS
HANDS ON TIPS FOR CRACKING THE INTERVIEW
SAP BusinessObjects is one of the most matured BI tools in the market. This is also very clear when we have a look on SAP BusinessObjects architecture. In the following figure 3, data sources establish the first layer in our architecture. Data can been extracted from different sources such as relational database management systems (RDBMS), other SAP products (e.g. SAP Business Warehouse (BW) or SAP HANA), and finally from external sources like TEXT, Excel, CSV and web services.
A key feature in SAP BusinessObjects is the introduction of the Semantic Layer. The semantic layer, or the universe, is a view of the organization’s data. And because universes are based on business terminology that is familiar and shared throughout the organization, they shield users from the technical complexities of the databases where your corporate information is stored.
Data Federation Engine: Data Federation Engine allow data access from multiple data sources at the same time. Data federation Engine provides the virtual data access from these sources, which means that the data will physically remain stored in their data sources and there are no changes or business logic applied to that data at their source.
Data Foundation: Data Foundation contains the universe structure of tables and joins. Once connected to a data source, the user can extract relevant tables from the data source and insert the appropriate join. Data foundation can be based on one or more relational connections. For a single-source universe, user can start with one connection identifying the database source. In case of multiple data sources, user need to create a multisource-enabled data foundation.
Business Layer: Business layer is based on Data Foundation. The business layer is mapped to tables and columns in data foundation and contains a collection of classes and objects that represent what end user needs.
Query and calculation engine: Query and calculation engine works at the query run-time. This engine will enhance the query reading performance and will also do some calculation on dataset if defined by business logic.
Web services: BO web services, like live office, along with BO web applications, like the Central Management Console (CMC), constitute the conceptual web tier for the BI platform. Both are deployed on a Java web application server. Web Services provides functionalities such as session authentication, user privilege management, scheduling, search, administration, reporting, and query management.
Front end / Presentation layer: BO front end, or the presentation layer, consist of the different BO applications and clients, through which the end user perform the reporting, querying and data management activities. These applications can either be access via the web-based BO portal (i.e. BI launch pad) like Web Intelligence or via a desktop-based clients, like Web Intelligent Rich client, Dashboards, or Crystal Reports.
