Mention what is the importance of ODS in BIW?
An ODS object serves to store debugged and consolidated transaction data on a document level. It defines a consolidated dataset from one or more info-sources. This dataset can be evaluated with a Bex query or an Infoset query. The data of an ODS object can be updated with a delta update into InfoCubes or other ODS objects in the same system or across systems. In contrast to multi-dimensional data storage with InfoCubes, the data in the ODS object is stored in transparent, flat database tables.
