02 Apr 2009 If you've had experience with CA ERwin Data Modeler and now
are starting to learn InfoSphere™ Data Architect, this paper will speed up your
model migration process and ease your learning process of the new environment.
You will learn the differences between the two design environments, and you'll
also learn a set of best practices for using features of InfoSphere Data
Architect that will put you on the fast track of working productively in
InfoSphere Data Architect.
IBM InfoSphere Data Architect is a collaborative data design solution to
discover, model, relate, and standardize diverse and distributed data
assets. This product used to be known as Rational Data Architect, and
many of the existing materials on the Web still refer to this name.
Some of the best practices recommended for
the migration process include:
- Models that contain entities related to
different subject areas in ERwin should be organized into smaller packages
(subpackages) in InfoSphere Data Architect.
- Models that are large or
would be shared and changed by multiple people in a team environment in
ERwin should be partitioned into submodels in InfoSphere Data Architect.
This offers the benefits of team collaboration, less consumption of system
resources, and improvement of model performance.
- Models that have more
than one package (such as more than one subject area) in ERwin should use
the unique InfoSphere Data Architect navigation diagrams to quickly
traverse from one diagram to another.
