Categorization

Categorizing content has major benefits: it simplifies access control policy design and management as System Administrators can specify access on an aggregate set of master data items. As a result, content becomes more easily searchable and accessible to users through navigation. Having intuitively navigated to one item, users are likely to find many related items of potential interest.

Product categorization was available in the Siebel 6.x data model. However, Release 7.x supports categorization of additional data structures such as auction items and literature items.

Data Migration to Support Categorization

In Siebel 6.x, categories could be shared across multiple catalogs and could have multiple parents. In Release 7.x, a category can only belong to one catalog and have at most one parent catalog. To accommodate the new structure, the database upgrade generates copies of categories and category hierarchies that were previously shared across multiple catalogs.

For example, the following catalog and category hierarchy:

                          CATd
CTLG1            CATb
        CATa              CATe
CTLG2            CATc
                          CATf

results in separate hierarchies of copied categories after the upgrade:

                         CATd
                 CATb
                         CATe1
CTLG1    CATa
                         CATe
                 CATc
                         CATf

                         CATd
                 CATb
                         CATe1
CTLG2    CATa
                         CATe
                 CATc
                         CATf

NOTE:  For more information about categorization, see Security Guide for Siebel eBusiness Applications.
