Chapter 1
Introducing the JDBC/ODBC eWay
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.
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
