JDBC and ODBC APIs are supported. Embedded and server modes are available. A Web console application is included. Clustering is supported. This is a client/server application, so both a server and a client (a browser) are required to run it.

If you start the server, you may get a security warning from the firewall (if you have installed one). If you don't want other computers in the network to access the application on your machine, you can let the firewall block those connections. The connection from the local machine will still work. Only if you want other computers to access the database on this computer, you need allow remote connections in the firewall.
