Querying (Filtering and Sorting)

 Conceptual overview

After you have created a view, you can query (filter and sort) its information in a variety of ways. Filtering restricts the information being displayed, and sorting determines the order in which information is displayed. For example, in an Attribute Matrix, you may want to order requirements information from highest to lowest priority (sort criteria) and view only those requirements assigned to you (filter criteria).

You filter and sort requirements by applying query criteria to the attributes. These criteria limit the values of the attributes or limit the traceability relationships. You can create a simple query involving only one attribute, so that you can see the results of each query. Or you can create a query that filters and sorts all at once for several attributes.

For example, you might create a query such that only requirements having a high or medium priority are displayed. You can use this information to determine which requirement features you will implement at various stages of the project.
