....formalism for managing large and complex schemata, and at the same time maintain a bridge between the actual raw data and the semantic structure [CLN98] Entity Relationship is one of the several semantic data models introduced as formalisms for data modelling. To the original ER model [Che76] on the 1 With respect to ALC, ALCNR provides the number restriction and the role conjunction. 54 last years a wide range of semantic data models have been added to the panorama; part of them are mere extensions of the original model, while others completely new formalisms. More or less all the ....

....objects, and separate from other objects representing other behaviors and relationships in the same system. An integrated behavior is represented as a set of independent behaviors integrated in a network of externalized behavioral relationships. Recalling Chen s entity relationship data modeling [Chen 76] I call these networks behavioral entity relationship (ER) models. 3 1.4.1 Applying the Method The top part of Figure 1.7 depicts a behavioral ER model of the behavior of the integrated programming environment. Having produced this model, the second step of the mediator method produces an ....
....which the separation of relationship concerns figures prominently. 133 9.1. 1 Entity Relationship Data Modeling Separating the representations of relationships from those of the entities to be related in software engineering dates at least to Chen s entity relationship (ER) data modeling method [Chen 76] Before Chen, data modelers tended to represent relationships in terms of attributes (fields) of the entities (relations) to be related. To represent the employment of an employee by a company, an employee record would contain a field holding the identifier of the record for the corresponding ....

....The first phase articulates the decomposition of the system into modules. The second defines phase the module interfaces in a form suitable for efficient implementation. We call the first phase behavioral entity relationship (ER) modeling because it applies entity relation data modeling ideas [Chen 76] to decompose integrated system behaviors . One first identifies the behavioral components of the system that should be independently developed and (re)usable. Then one separately identifies the behavioral relationships needed to integrate these behaviors to produce the required system behavior. ....
