What is canonical data modelling?
Defining a Canonical Data Model (CDM)
CDMs are a type of data model that aims to present data entities and relationships in the simplest possible form to integrate processes across various systems and databases.
What is the difference between logical, and conceptual data models?
The logical data model is an abstract representation of a possible implementation, without being bound to any specific implementation, while the conceptual data model is a high level representation of the business requirements and the connected data sets and relationships.
What are the 3 types of data Modelling?
What are the types of data modeling? The three primary data model types are relational, dimensional, and entity-relationship (E-R). There are also several others that are not in general use, including hierarchical, network, object-oriented, and multi-value.
What is a logical database model?
A logical data model establishes the structure of data elements and the relationships among them. It is independent of the physical database that details how the data will be implemented. The logical data model serves as a blueprint for used data.
