“Design Patterns”,
- Mike
Florida International University professor Dinesh Batra defines design
patterns in the context of data modeling as descriptions of objects,
relationships, and attributes that are customized to address a generalized
conceptual or logical database design problem. He examines a number of sources
and from them extracts 11 data modeling patterns that are commonly found in
business applications. Those patterns are identified as entity event, entity
type, generic transaction, discrete transaction, time-based transaction, data
warehouse, subsequent transaction, recursive, strict hierarchy, plan, and generalization.
Batra validates these patterns by analyzing how often they crop up in three
data model sources; one source is aimed at data modeling students and the other
two target practitioners for the most part. The author concludes that most of
the structures occur frequently enough in the sources to be considered
patterns, although some patterns are employed more frequently than others. Type
structure and transaction structures (generalization especially) are
underrepresented in the academic source, while the plan structure is completely
absent. The hierarchy structure is poorly represented in two of the sources,
leading Batra to speculate that the hierarchy pattern may need to be renamed.
The three sources alternately designate generalization, type, and transaction
as the leading pattern.
