In this paper, we describe design transactions in terms of the DAMOKLES data model as a flexible concept to enhance parallelism of design ac

Summary of Results and Further Research, major component in this environment is a set of structure-oriented editors that manipulate a hypertext-like document-structure. SOOM is a datamodel based on a merge of ideas from structural and behavioral object-oriented datamodels, where relations are added to an object-oriented language, Smalltal

In order to accomplish a seamless integration of a formal database specification system with object-oriented constructs, we need to supply formal semantics f

These rules generalize mechanisms such as assertions, triggers, alerters, database procedures, and production rules that have previously been proposed for supporting such DBMS functions as integrity control, access control, derived data management. and inf

To this end, topics rarely addressed so far in this area must be investigated, among them full incorporation of dynamic aspects, static and dynamic integrity checking, formal methods strongly backed by a sound theory, and design-in-the-large issues

The formal representation supports the ability to analyze and explain constraints; the uniform representation allows both inherent and explicit constraints

The extensible nature of an OODBMS, i.e., the provision for abstract data types and operations, makes it feasible to write interfaces to a wide variety of existing information sources and that way create the illusion of a single integrated database which can be queried i
