Data modelling is the representation of structures within a business’s database. The models are typically presented in either a table or flowchart and these diagrams are mostly compiled from symbols and copy. It is a representation of how a software system is designed and how the data moves through it.
The diagram outlines the skeleton of a structure; they can be easily understood and interpreted which ensures any new software or adaptations to existing software will follow the same configuration.
Data models are used for a range of reasons, across many levels of the business. The main types include Physical Data Models, Conceptual Data Models, Enterprise Data Models and Logical Data Models. Each of these models addresses and identifies the relationships between data.
Comprehensive data models allow the identification of errors within the system before any code has been written, which saves time, resources and prevents faults when the software is live. It also ensures complimentary software or alterations follow the same data flow.
