A Query Model is made up of ‘parts’ such as screens, tabs, field names,drop down menus, text entry boxes, selection check boxes and buttons.

All Query Models have at least one screen. Each screen has an associated Tab.

Index is the Tab for this screen.

These data elements are related to INDEX data.

Any data element that is selected with a check mark in the selection box will be returned in the results set of the query.

Sometimes a screen will appear with a pre-selected data element. Data will automatically be displayed in the results set for this data element.

If you submit your query and have not entered or selected a value for a required field, a message will display and the Query will not execute.

Clicking on a data element will display the definition of that data element.

This page is displaying the definition of Index.

You can access ‘DataLink’ for additional information.

In this case, you can select a qualifying parameter that you can use to customize your query.

In some cases, you can choose one or more selections from a list.

This section describes ways to customize your query by entering ‘values’ for data elements.

If a data element’s text entry box displays as empty,without any downward pointing arrows or scroll bars, you can enter a value for that data element.

This is a value for the ‘Organization’ field.

Selecting the in list parameter allows you to enter more than one ‘value’ for the field.

Use the List Wizard to enter the values you desire. Click OK.

The parameter displays as ‘in list’ and the values display in the text entry box.

You may want to use the advanced parameter option.

With the Advanced Wizard you can enter combinations of qualifying parameters with specific values. Click OK to activate.
