37) What are some Performance Considerations while modeling in GEN, COOLGEN, CA-GEN ?
Two tips.
· Use denormalization and extended READs (READ several
entity views at a time) rather than collapsing entity types together to improve
retrieval performance when entity types are joined by a relationship that
allows denormalization.
· Try to stabilize your Data Model as much as possible
before performing action diagramming.
This reduces the likelihood that an attribute has been or will need to
be added which should have been a foreign key from a relationship. It also reduces the likelihood of attribute
movements or identifier changes. This
can cause integrity issues or require you to change your action diagrams.
