Logical data modeling conventions

There are numerous logical data modeling conventions you can use to enhance your logical data model. These include:

• Unique identifiers

• Cardinalities and ratios

• Attribute forms

These logical modeling conventions can provide cues for system optimization opportunities, help with system maintenance, and make for a more robust logical data model. Although the user community is the ultimate beneficiary of a well-optimized and maintained system, these conventions are primarily intended for project designers, administrators, and advanced report designers.

Each convention adds more information about the data to the logical data model. This additional information can be particularly useful to a person learning about the system.
