Data Modeling Diagrams

Totem can organize all of your file relations in a Data Modeling Diagram (DMD). This is an extension of Entity Relationship Diagrams (ERD), which portray all entities in boxes organized and connected by arrows representing relationships. The DMD presents your files and their relationship to each other in a comprehensive and logical format. A DMD thus provides a friendly diagramming environment so that you can visually organize your project’s FD files and define their relations.

A DMD shows you how your files fit together. A DMD also allows you to modify an entity’s definition and to define the relationships between entities. Once you have defined those relationships, Totem will automatically generate the code for them, as needed in a Data Set Diagram.
