Sun Microsystems JDBC/ODBC Adapter specification

Chapter 1	Section 1.1
Introducing the JDBC/ODBC eWay	About Java Database Connectivity (JDBC)

Cons: Not optimized for server operating system, so the driver can't take advantage of operating system features. (The driver is optimized for the database and can take advantage of the database vendor's functionality.) User needs a different driver for each different database.

A native-protocol fully Java technology-enabled driver converts JDBC technology calls into the network protocol used by DBMSs directly. This allows a direct call from the client machine to the DBMS server.

Figure 4 Typical Type 4 Driver Configuration

The pros and cons for using this type of driver are as follows:

Pros

Allows access to almost any database since the databases ODBC drivers are readily available

Offers significantly better performance than the JDBC/ODBC Bridge and Type 2 Drivers

Scalable

Caching

Advanced system administration

Superior performance

Advance Java feature set

Does not require applicable database client libraries

Cons

Each database will require a driver
