Using queries Lesson 8: Exploring What You’ve Done 124 6 In the form navigation toolbar, click on the Open tool. FrameWork opens the Composite Use Case Object form for the Hire Employees use case in the same window you’ve been working in. 7 Use the form navigation toolbar to open the Use Case Information form for the Interview Candidates capability. Try it yourself Take a few minutes to explore the objects you’ve created in your use case, statechart, and Java class diagrams. FrameWork comes with forms for viewing all types of objects. Try to use both of the navigation techniques you’ve just learned. Experiment with the Go Back ( ), History ( ), and Go Forward ( ) buttons in the form navigation toolbar. Using queries Tip You can also explore the objects in the DemoExample KnowledgeBase, which you used in Lesson 1, “Navigating FrameWork.” Many of these objects have more detail than the objects you’ve created in this tutorial. Queries A query is a request to FrameWork to retrieve information from the KnowledgeBase. To make the request, you invoke the query for a specific object. This is called evaluating the query on the object. Like forms, each query is defined to work on a particular type of object. How queries work A query works by using associations to navigate through the KnowledgeBase and by using set operations to manipulate objects along the way. The result of a query is a set of objects. Because of the operations they perform, queries are often able to retrieve information that is not directly available for an object.
Using queries What you do In this lesson, you’ll evaluate queries on the Qualified Candidate class in the Employee Hiring Classes diagram. To do this: 1 Open the Employee Hiring Classes diagram if it’s not open already. 2 Select the Qualified Candidate class. 3 On the Queries menu, select Evaluate. FrameWork opens the Evaluate Query dialog box. The Evaluate field lists the queries you can evaluate on the Qualified Candidate class. 4 In the Evaluate field, scroll down to find the CLASS superclasses query. Then double-click on it.
