Complex Values in Databases
J.H. ter Bekke
Abstract
Shortcomings of the relational data model have led to two different
approaches for supporting complex values: the object oriented approach,
in which they are modeled as a unit and represented as such in the database,
and the semantic approach, in which complex values are derived from a simple
conceptual structure. This paper contains an overview of the pros and cons
of both approaches. An analysis indicates that generally derivation of
complex values is superior to modeling and representation of complex
values.
Keywords: data modeling, object oriented databases, semantic databases,
user interfaces, view independence, data independence, knowledge
representation.
