Native-Protocol All-Java Drivers (c-treeSQL JDBC Driver)

Type 4 drivers are also written completely in Java, but do not rely on middleware. They convert JDBC calls directly into the network protocol used by a particular database. This approach allows a direct call from the client system to the database server. Also, since there is no client-resident software, it also is practical for Internet applications.

Type 4 drivers provide the best performance.

The c-treeACE SQL JDBC Driver is a Type 4 driver.
