Modifying Access Path Relations

This topic discusses required relations and provides instructions on editing access path relations.

The relations for an access path are composed of the set or subset of a file's relations that apply to a particular access path. For a specific access path belonging to a given file, only some of the relations specified for the file need to apply.

In other words, a particular access path may not require all of the fields and relations from the file to be present on the access path. Each access path may have its own subset of the file's attributes and relations. When you drop file-to-file relations, such as Refers to, those key fields associated with the relation are dropped as are all associated virtual fields. The following is an illustration of access path and file relations.

For more information about relations, see the Using Relations section of the "Understanding Your Data Model" chapter in Defining a Data Model.
