Uncertainty, Fuzziness, Object-Oriented Databases, Conceptual Modeling, and Geographic Applications 1 Introduction In general, a conceptual model is a type of abstraction that uses logical concepts and hides the details of implementation and data storage. Questions that are addressed during conceptual design: { What are the entities and relationships of interest (mini-world)? ).

This phase consists of three parts: the conceptual design, the logical design and the physical design. . Woman doing a handstand with a computer . The conceptual database design phase starts with the formation of a conceptual data model of the enterprise that is entirely independent of implementation details such as the target DBMS, use of application programs, programming languages used, hardware platform, performance issues, or any other physical deliberations. … N : 1 if for every entity e 1 in A there is at most one entity e 2 in B such that R(e 1;e 2). Therefore, it can also apply NoSQL database design. This paper. 0000003462 00000 n – What are the integrity constraints or business rules that hold?
