objects. While all of the methods declared by this interface execute on the server,
they are accessible to client applications through a helper class.
The Persistent Object Manager brokers persistence requests and forwards them to
a PersistentDataService to handle the actual persistence operation. The protocol
used to pass objects back and forth to the Oracle Persistent Data Service is a
combination of introspection and JDBC calls to stored procedures. Introspection
is used to bind the attributes to stored procedure variables.

File Content Indexing
This section provides a conceptual overview of Windchill's indexing capabilities.
For information about the maintenance of collections with Convera
RetrievalWare, see Administering RetrievalWare Libraries. For detailed
information about creating an indexing policy, see the Windchill Business
Administrator’s Guide.
Each file that is managed by Windchill has metadata attributes that are useful in
identifying the file, including its purpose, MIME type, description, time of
creation, and so forth. (Attributes can be added as desired). Files may also be
related to domain-specific objects, further identifying their purpose and use, and
providing a means to locate the appropriate file and version.
Still, in some cases, metadata attributes and relationships may prove insufficient
to find a desired file, particularly in situations where it is not known if a file exists.
In such a case, the ability to search for key words and phrases that are contained
within the body of the document (file) represent the best mechanism for locating
documents. This capability is used by Web search engines such as InfoSeek,
AltaVista, and Lycos.
