Is there not performance degradation when accessing the contents of files managed by Data Links?
No. Data Links does not add any overhead to the file READ and WRITE operations. As described earlier, Data Links ensures referential integrity of file references from the database by intercepting file operations such as OPEN, DELETE and RENAME that could compromise the integrity of the file reference. File READ and WRITE operations do not compromise referential integrity and are therefore obscured from Data Links line of sight . Also, given that the number of file READ and WRITE operations generally outnumber the occurrences of OPEN, DELETE or RENAME on a file, the performance degradation if any is minimal to marginal.
