Temporal Constraints for Object Migration and Behavior Modeling Using Colored Petri Netsal rules with conditions referring to temporal intervals. Additionally, temporal multiplicity constraints are represented by object-schemas. Furthermore, the paper proposes OM behavior modeling using Colored Petri Nets (CPN) based on temporal consistency constraints.

IS=DBS+Interaction: Towards Principles of Information System Designdamentally different set of IS design principles, as compared to conventional database design. We provide some promising directions for a formal study of IS models, based on the observation that interactive behaviors cannot be reduced to algorithmic behaviors.

Practical Approach to Selecting Data Warehouse Views Using Data Dependenciese during view selection and suggest heuristics based on data dependencies and access patterns that can be used to measure if one set of views is better than another set of views, or used to improve a set of views.

Semantic Analysis Patternsrticular, a new type of analysis pattern is proposed, called a Semantic Analysis Pattern (SAP), which is in essence a miniapplication, realizing a few Use Cases or a small set of requirements. Using SAPs, a methodology is developed to build the conceptual model in a systematic way.

A Pragmatic Method for the Integration of Higher-Order Entity-Relationship Schemataty-Relationship model and its theory of schema equivalence and dominance. The rules are embedded in a pragmatic method telling how they should be applied for integration. The method has been applied to various schemata of realistic size.

Tool Support for Reuse of Analysis Patterns — A Case Studyg the search for an appropriate pattern within such a library is one approach addressed inthis area. A tool for this purpose has been partly implemented and the results from a case study testing this tool are reported here.
