TheData Modelingprocess creates a data model for the data that we want to store in the database. The data model is a theoretical depiction of the data objects and the relationships among them. A Data Model looks like a building plan of an architect, and it assists in building a conceptua...
JetBrains DataGrip provides a database diagramming tool to construct a model from an existing database. These diagrams can be saved to UML or PNG. This is great for physical data modeling. Erwin Data Modeler is a very popular tool that supports conceptual, logical, and physical data models....
Finalizing the data model and validating its accuracy with test queries Depending on the type of data model—conceptual, logical, or physical—the diagram you create can include varying degrees of simplicity, detail, and abstraction. Data models are not static documents—they’re meant to be updat...
A simple database model sample is presented to help users get familiar with this kind of diagram. With this easily customizable template, users can represent any existing database model diagram.

2: Refine the structure of the diagram After you create a database model diagram, the work of refining the diagram begins. You can add and customize the three main components of a model: Entities(or tables), Columns(which describe facts about a table...
This diagram provides technical details and perspectives, but is not completely implementation-ready. As a consequence, you might want to think of the LDM as still associated with visualizing higher-level ideas than with a physical data model. Logical data models can be used for: Reviewing data...
