Some examples for the use of dialogs:

    Filtering a single system

    If the user should only select one particular system, it is best to define a lookup box (similar to a drop-down list).

    Filtering multiple systems

    To enable the selection of multiple values at the same time, use a checked list box.

    Filtering systems using an SQL statement

    The desired data can be filtered by applying an SQL statement to the data source. The selected values are stored in variables and can then be used in SQL statements.
