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).
The result of a DbView query can be send to another (VO) application via SAMP.
For example topcat can be used, the advantage of topcat is that it comes with a SAMP hub.
A SAMP hub must be running, otherwise the connection can not be made.
Click on the "Send via SAMP" button to send the current result to other SAMP enabled applications.
When sending via SAMP it is not the data that is send, but the URL of the data. The receiving application
will open the URL and interpret the resulting VO table.
If the SAMP connection does not work please try the following:
