In this study, a two-stage conceptual data modeling approach is proposed to reduce the level of complexity, to improve the understandability of database models and to improve the quality of the ...

Historically, two conceptual modeling constructs have been used within the database literature to represent composites: entity classes or object classes, and relationship classes or associations.

Yet, in the development of spatial and temporal applications, we see that few constraints are typically modeled during conceptual database design. In contrast, few spatio-temporal constraints are ...

Through this overview, we also aim to address the areas of greatest confusion in the literature. We synthesize the literature outlining the most exciting conceptual advances in the field of ...
