Embedded: Allows only a single application to access a database at one time.

In the embedded environment, no network access occurs.

When you load a JDBC driver from a Java program, JavaDB automatically starts in the embedded environment.

Client/server: Allows multiple applications to connect to JavaDB over the network.

To start JavaDB in the client/server environment, you need to use the server command line tool of JavaDB.
