DSO component consists of three tables :
Activation Queue : This is used to store the data before it is activated. The key contains request id, package id and record number. Once activation is done, request is deleted from the activation queue.
Active Data Table : This table is used to store current active data and this table contains the semantic key defined for data modeling.
Change Log : When you activate the object, changes to active data re stored in change log. Change log is a PSA table and is maintained in Administration Workbench under PSA tree.
