Documents and Files

This information model distinguishes the logical Document Content from the physical representation of that Content – usually a FILE object.

The Document Content and the physical File are represented in the database by separate Objects linked by an ‘is fulfilled by’ Association.

In this example, SCHEMATIC would be a subclass of DOCUMENT CONTENT.

It is important to notice that Associations such as refers to are between the DOCUMENT CONTENT object and the PUMP – not between the FILE object and the PUMP.
