Usually does not perform as well as type 2 drivers
The vendor client library needs to be installed on the
client machine.
Cannot be used in web-based application due the client side
software needed.
Not all databases have a client side library
This driver is platform dependent
Performance overhead since the calls have to go through the
JDBC overhead bridge to the ODBC driver, then to the native
db connectivity interface.
The ODBC driver needs to be installed on the client
machine.
Considering the client-side software needed, this is not
suitable for applets.
Requires database-specific coding to be done in the middle
tier.
An extra layer added may result in a time-bottleneck. But
typically this is overcome by providing efficient
middleware services described above.
At client side, a separate driver is needed for each
database.
