PrimaryKey¶
Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::DataDescription::Components::PrimaryKey
Definition¶
Role of a set of data structure components for content linkage purposes
Explanatory notes¶
Equivalent to primary key in the relational model. A primary key essentially indicates which data structure components correspond to key members. It can also be used in conjunction with foreign key to link data structures and their related datasets.
