Data Links treats information residing in file systems as though they were logically within the database, leaving existing applications untouched. DB2 UDB’s object-relational capabilities permit an application designer to either write UDFs that process files either stored within Blobs, or are referenced by a DATALINK column or a UDT. If files are stored within BLOBS, and are also currently used in existing applications, then the potential exists for synchronization problems between the BLOB and native file information. Therefore, while both features support file processing via the database, they address different application requirements, and are complementary in nature. DB2 UDB is unique in the industry in offering the customer these two choices to best serve the custom demands of their application.
