This is differs from the type of 4 driver in that the protocol conversion logic resides not at the client, but in the middle-tier. However, like type of 4 drivers, the type of 3 drivers is written entirely in the Java.

The same of driver can be used for multiple databases. It depends on the numerical number of databases the middleware has been configured to support. The type of 3 drivers is platform-independent as the platform-related differences are taken care by the middleware. It is also, making to be use of the middleware provides additional advantages of security or firewall access.

A net-protocol fully the <a href="http://www.expertsmind.com/programming-solutions/java-homework-assignment-project-help.aspx">Java assignmant help</a> technology-enabled driver translates JAVA DATABASE CONNECTIVITY API calls into a DBMS-independent net protocol which is then translated to a database management system protocol by a server. This is net server middleware is able to connect all of it is Java technology-based clients to many different databases. The specific protocol used depends on the vendor. In normal, this is the very most flexible JAVA DATABASE CONNECTIVITY API alternative. It is likely that all vendors of this solution will provide products suitable for Intranet uses. In order for these products to be also support Internet access they very must handle the additional requirements for security, access through firewalls, etc., that the Web imposes. Several vendors are adding JAVA DATABASE CONNECTIVITY technology-based drivers to   their existing database middleware products.
