Type 4 driver disadvantage


The JDBC type 4 driver is known as the Direct to Database Pure Java Driver. It is a database driver implementation that converts JDBC calls directly into a vendor-specific database protocol. It is a platform independent driver and it gets install inside the Java Virtual Machine of the client. It provides higher performance then its counterparts and it also doesn't have the overhead of conversion of calls into ODBC or database API calls.

It is vendor specific and it requires separate drivers which is provided to the vendor to connect to different types of databases. For example Oracle thin-driver.

The main disadvantage to this is that drivers are database dependent, as different database vendors use widely different (and usually proprietary) network protocols.
