As descriptions of navigation paths correspond to “telling stories” about the system usage, a conceptual model for application stories is needed. This chapter highlights the key concepts o

Conceptual-Model Programming: A Manifestoftware development..Essentially, this CMP manifesto asserts that programming activities are to be carried out via conceptual modeling. For applications amenable to conceptual-model designs, software developers should never need to write a line of traditional code. Thus, programming is actually conce

Model-Driven Software Developmentdes now, researchers have proposed “model-driven” approaches to improve the state of the art in software engineering. Software models are intended to improve communication among stakeholders and aid in the overall understanding both of a problem space and a proposed software solution that satisfies

The Entity-Relationship Model (Reprinted Historic Data)ld. A special diagrammatic technique is introduced as a tool for database design. An example of database design and description using the model and the diagrammatic technique is given. Some implications for data integrity, information retrieval, and data manipulation are discussed..The entity-relati

Mapping Conceptual Models to Database Schemasiples and practices of algorithmically mapping conceptual models to database schemas. An important unifying theme is that the underlying principles are independent of conceptual-modeling languages and notation. Although illustrated mainly in terms of the entity-relationship model, the chapter explai

The Enhanced Entity-Relationship Modeler-order relationship types. These extensions still allow a hierarchical construction of schema items. Therefore, a layered predicate logic can be defined. Classical integrity constraints are thus definable on the basis of this logics. The structuring of a database consists of a schema together with
