Summarize the UML Modeling and Generation

What this episode covers

1- Database Schema Modeler Create a database diagram, navigate to a database connection or create a new connection. Select the table(s) you want to appear on the diagram, and then add objects to the diagram using the Component Palatte. Generate the DDL script using the Generate SQL from Offline Database Wizard. Update a table through its Properties, then re-run the wizard only this time indicate Update rather than Create. Use the context menu to execute the SQL against the required schema. 2- Java Class Modeling After the developer uses the drag-and-drop function to place the project on the diagram page, using the Drill Down menu option will display the classes in the package. JDeveloper 10g supports a number of styles of diagram layout; Symmetrical, Hierarchical, and Grid. The Java Class Modeler automatically synchronizes the diagram and the code, regardless where the changes are made. The developer can add a new method in a class by editing it directly from the diagram. The refactoring process identifies the dependencies, implements the changes, and recompiles the project; this is all done from the diagram. More than one package can be displayed on a diagram, and the dependencies drawn between them. You can Run and generate a html file to open the JavaDoc. This will show all the diagrams and classes. 3- UML Activity Modeler Oracle JDeveloper 10g supports UML Activity Modeling. In this feature, the developer can add Swimlanes for separate processes/activities. You can drag activities from the Applications Navigator onto the diagram. You can also drag the object flow from the Structure Pane to the diagram as well. Complete the flow with a Final State on the diagram. To complete the diagram, an OR decision point should have guard conditions on the outcomes. 4- UML Use Case Modeler UML Use Case Modeling is used to create a visual diagram of actors and flow, add requirements details in HTML, then publish the specification in JavaDoc. You can drag-and-drop Actors from the Component Palette. Where a use case requires more detail, use the “fully-dressed” option which will create a detailed template. When less detail is needed, use the “casual” template. Various functions assist with the diagram layout such as auto-layout, align and distribute. For more documentation, you can add notes to the diagram or URL links to external documents. The requirements in the diagram can be published in JavaDoc HTML form, and accessed on a server for reference. 5- UML Class Modeler UML Class modeling enables the capture of requirements in a technology neutral visual model to validate user requirements, and document complex applications. Use the UML Class Diagram in your new workspace, add classes by the drag-and-drop feature, and then associate them to each other; one-to-many association, many-to-many, etc. Add some attributes and methods to the classes and also Operations through the Class dialog. You can transform the UML analysis model into a visual Java design model and implementation files. Publish the UML models as graphics files or insert into a JavaDoc HTML document to be reviewed or referenced.
