“ A
Simple Alternative to the Relational Model ”
|
|
| |
|
|
| |
Abstract:
A simple alternative to the relational model is developed, based on the conceptual
view. It defines all tables as relations of degree two, the entity field or
fields and the attribute fields. The explicit designation of the intended entities
and their attributes removes the need for the insertion/deletion anomalies,
explicit decomposition of tables, and the need to explicitly check for entity
and relational integrity. These are accomplished through the initial design
of the tables, in the designation of the attributes and the intended entities.
