To personalize the DBViewer, a new user should first log in with his or her username. Optionally, a user can click a project if wanted (log-in + project: see top row).
After these steps the user can click one of the table categories listed on the start sceen (but also present at the top right).
Each category consists of a list of tables, with each table having, if available, a link to a table description.
After clicking a table, the user is shown a query screen with lots of attributes to be queried.
The query page consists of a tree view of the current class and all its
dependencies and attributes. The dependencies can be unfolded, the
attributes can be used to query on. If a dependency is unfolded when the
submit button is clicked the output will contain the attributes of this
dependency. There are three different kinds of attributes to query on :
The following operators are supported, although not every attribute type supports all of them :
There are two sets of parameters: general parameters and local parameters. The general parameters can be accessed from the top row under 'preferences'. The local parameters are always located above the query page. Below is a description of all parameters. Suggestions for additional parameters are welcome! Please use the contact page (see top row).
After querying, the output is visible in the dbviewer. This output can be send to external (VO) programs like topcat etc.
In order for this to work, three steps should be carried out, which are shown as links above the header of the table.
Java will store its setting at $HOME/.java.
To restore your old java settings, close the browser and rename the .java.old directory to .java.
