Introduction

This section of the documentation covers the features available to administrators of an application using this appjar.

Data Query gives an administrator four management areas, each documented on its own page:

• Query Definitions — the central screen. A query definition holds the query itself, the parameters it accepts, the columns it returns, its chart configuration, the queries it depends on, and the printed report attached to it. Everything a user eventually sees comes from here.
• Query Categories — groups of related queries, used to keep a growing list of definitions organised.
• Dashboards — pages that arrange several queries as widgets on a resizable grid, each published at its own address.
• Report Designer — the visual canvas used to draw the printed layout of a query, so that its export produces a laid-out PDF rather than a tabular dump.

Warning

A query body is executed against the application's data source, so an administrator who can create a query definition can read any data that the connector reaches. Access to these management screens should therefore be restricted to trusted administrators through the application's own security configuration. The appjar does not restrict them by itself.
