Does anyone knows this guy? I just go this from ACM:

so I am going to drop him a note making him aware of “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.
