Conceptual Models – What Are They and How Can You Use them?
At the heart of database modeling is the idea of designing a database structure that defines how stored information can be accessed, categorized and manipulated. It’s the very foundation of a database design effort, and the specific data model employed drives the database diagram and overall... The purpose of the conceptual design phase is to build a conceptual model based upon the previously identified requirements, but closer to the final physical model. A commonly-used conceptual model is called an entity-relationship model.

Conceptual Models – What Are They and How Can You Use them?

Conceptual data model: The highest-level view containing the least detail. Its value is showing overall scope of the model and portraying the system architecture. For a system of smaller scope, it may not be necessary to draw. Instead, start with the logical model....
The entries on Logical Data Model and Conceptual Data Model make them sound like the same thing: implementation-independent representations of business data. Then, the entry on Database Design contradicts them by stating that the logical model “contains all the needed logical and physical design choices and physical storage parameters needed to … create a database.”

Conceptual Models are great to use when introducing a topic. Get students interactively involved with the creation, evaluation, and refinement of conceptual models. Ask questions that guide them in the development process. Causal Loop diagrams are a great tool for developing and understanding

  • A general understanding to the three data models is that business analyst uses conceptual and logical model to model the business objects exist in the system, while database designer or database engineer elaborates the conceptual and logical ER model to produce the physical model that presents the physical database structure ready for database creation. The table below shows the difference

  • Conceptual design begins with the collection of requirements and results needed from the database (ER Diag.) Logical schema is a description of the structure of the database (Relational, Network, etc.) Physical schema is a description of the implementation (programs, tables, dictionaries, catalogs
  • A data model is a conceptual representation of the data structures that are required by a database. The data structures include the data objects, the associations between data
