SAP BI Real Time Interview Questions (Part -9)

Q: What is the significance of ODS in BIW?
An ODS Object serves to store consolidated and debugged transaction data on a document level. It describes a consolidated dataset from one or more InfoSources. This dataset can be analyzed with a BEx Query or InfoSet Query.

The data of an ODS Object can be updated with a delta update into InfoCubes and/or other ODS Objects in the same system or across systems. In contrast to multi-dimensional data storage with InfoCubes, the data in ODS Objects is stored in transparent, flat database tables.

Q: What is Bex?
BEx (Business Explorer) is the reporting tool used to work with data in the BW database. BEx has a Web-based user interface and is made up of two components, the BEx browser and the BEx analyzer. The BEx browser provides an organized interface where a user can access and work with any type of document assigned to them in the Business Information Warehouse, such as workbooks, links, and BW Web reports. The BW database itself is segmented into discrete data areas called InfoCubes that are made up of data and associated metadata. The BEx analyzer allows the user to examine segmented data in a variety of useful combinations, for example when comparing financial data for different fiscal years.
