Filter Criteria Selection
The Filter tab sheet in the data frame displays a filter tree within a
subframe as a standard interface for initiating queries. It is a branching
diagram of the table's fields and of links to related tables. Clicking a button
will display the field structure of a related table. A click on the plus sign
beside any item displays fields and filter subtrees below the item.
A non-functional example can be accessed in the navigation frame via the projects tab sheet. Select the "Bryophyte Collections" item and open this project in the context menu (right mouse bottom). [In the current version, access to the items in the subtree is disabled.] Subsequently select the Filter tab sheet in the data frame.
- Defining queries: If there are no saved queries or a predefined query with the necessary search criteria, one can create a new query. To launch a new query, the subframe filter tree has to be accessed. When a data field in the filter tree is selected, a query form appears in a data frame. The query form can be used to define a search expression. [– to be implemented]
- Opening and saving queries. If one desires to receive data as a report, he needs to use a predefined query that already has a report format associated with that query. [– to be implemented]
- Running a query to one or simultaneously to more than one database: Selection criteria list (Display – Sort – Field Name – Not – Operator – Criteria). [– to be implemented]
- Interactive identification in connection with a DiversityDescription compatible database. [– to be implemented]
