Review of Rational Rose with special emphasis on its intergration between data modeling and object class models.
Continues to describe how scenarios can be used to capture and describe business rules.
Provides a scenario approach to process analysis as a methodology for capturing and documenting business rules
Provides an introduction to data reverse engineering and data mapping templates. Highlights the fact that data mapping is not just a data warehouse activity, but is required for any project that includes data interchange between applications.
Describes two data modeling styles that produce different models from for the same business rules. For flexibility, "meta-level" models have advantages over models that literally represent the current business rules. Provides example patterns that are accommodated through the meta-level model.
Review of the DataMaster (formerly CASE Essence) computer-based training product for data modeling.
Compares the star/dimensional model and relational model, presenting the premise that both types of models must co-exist in order to manage the information resource
Discusses some of the challenges we face in designing databases to support dynamic business models
Suggests that scenarios can be an effective approach, not only for identifying business rules, but in defining test data later in the development life cycle
Shows how common data modeling practices of generalization and aggregation, if not properly used, can obscure the business rules expressed by a business information model.
Warns against the urge to normalize business models too soon
Review of Fourth Generation Data and Designing Quality Databases with IDEF1X Information Models
As part of the change management series, discusses the important role attributes play in a flexible application
As part of the Change Management series, discusses the importance of attributes in designing flexible systems.
Identifies the various types of repository users and discusses how much each needs to know about the repository meta-model
Second article describing the IBM modeling language with comparisons to the Chen and IDEF1X modeling approaches.
First in a two part series on the modeling language IBM introduced with its repository.
Although the modeling language remained within the halls of IBM, many of its
constructs are similar to what is used in object class modeling today.
