Describes a particular type of data model which structures data into individual tables, each made up of fields which are linked together (related) through a system of key fields.
Refers to a database in which data is stored in multiple tables. These tables then "relate" to one another to make up the entire database. Queries can be run to "join" these related tables together.
Used most often with database programs that link data from different files as opposed to linking data types within one file. See also Three-Dimensional Capability.
