Modeling Large Objects
You can model an attribute to be a binary large object (BLOB) in one of the following four ways:
• By default when the attribute type is a class that does not map to any of the other java.sql.Types.
• Explicitly set the attribute’s class to LobLocator. Use this technique for large objects that you access infrequently.
• Model the attribute to map to a SMALLBLOB by changing the ColumnType property under the Windchill tab of the attribute specification. Use this technique for objects that can expand and contract, but are never more than a certain size.
• Model the attribute to map to an INLINEBLOB by changing the ColumnType property under the Windchill tab of the attribute specification. Use this technique for objects that can expand and contract, and are typically small in size, but occasionally require large storage size (such as, adhoc ACLs).
