The Data Sources node 
in
the Servers window provides you with a view of your data sources. From this node you can do the following things:
- Add new data sources and data source alias: connect to databases
and make them available to use in your applications; create data source aliases to existing data sources; import and export a set of data sources so that multiple developers can use them.
- See the data sources you have added as
subnodes of the Data Sources node.
- Navigate to the nodes for database tables and drag them
to your pages in design mode, enabling the components in your
pages to bind to tables in the databases.
To see the tables, views, and stored procedures of a database, expand the node for the data source.
- Close a database connection to a specific data source by
right-clicking the data source's node and
choosing Remove Data Source.
- Change the definition of a data source, such as its name
or the port it is connected to, by right-clicking the data
source's node and
choosing Modify Data Source.
