Organize Data Models under Use Cases

In helping you organize your modeling project, use cases can act as generic containers for all software development artifacts. Development teams can group and locate design artifacts by navigating use cases.

In this tutorial we are going to show you how to create a new data model (i.e. entity relationship diagram) and associate that with a use case. And in future, you can easily identify existing associations as such by use cases and conveniently, be taken to the related diagrams right on the spot in just a few clicks.

How to Perform Refactoring

In an ideal world of system design, we’d probably want to create a generic library to store common components for reuse. That way, we can avoid creating the same components over and over again. Also, any changes you need to make to a component will automatically be rippled down to all projects which point to the same generic library.

What to do If You Cannot Resize Shapes in a Diagram

Sometimes when you reopen your project and try to edit the diagram, you find that the shapes in your diagram are not resizable. This probably caused by you have turned on the auto-fit size option of your diagram.

By turn on this option, all the shapes in your diagram will be fitted its size automatically, thus, all the resize points around the shape will be disabled. Read more
