Answer 1

The best way to use HSQLDB for development is running a Server instance (which could store data purely in memory). While the server is on, you can connect from multiple clients, including GUI, to test and browse the data.

The URL form jdbc:hsqldb:hsql://localhost is used to access the server, while the server itself is using jdbc:hsqldb:mem:test as its internal memory database. The server must be started first with a command like this:

java -cp ../lib/hsqldb.jar org.hsqldb.Server -database.0 mem:test
