JDSA Manual
These pages aim to describe the JDSA or Java DataSource Administrator utility.
Tasks
How is a connection made ?
To make a connections from a Java application to a database, you require a driver. Many databases provide a Java driver to access their database. These are the JDBC drivers.
A Driver is a Java Class allowing the application to make a connection to a JDBC Data Source. Depending on the Driver, a URL will provide the information the driver needs to establish the connection and allow the application to execute SQL-commands on a Data Source.
The Database Connections tool allows you to define JDBC drivers. Orbit GIS provides a driver to your ODBC databases as defined in your Windows system.
In Orbit GIS, we will give a name to each individual connection by using this utility.
Portability
Note that when using external tables in Orbit GIS, i.e. joining a database table to a dataset, the JDSA name as specified in this tool is used in the ORD file to store the join definition. When moving the dataset to other systems (other instances of OrbitGIS or to an EOS server) beware to have the same JDSA connection defined on that computer in order to make the join work.
