There are four types of JDBC drivers: 1) JDBC-ODBC bridge driver, which uses ODBC to connect to databases but has performance issues. 2) Native-API driver, which uses client libraries but requires installation. 3) Network protocol driver, which uses middleware but requires database-specific coding. 4) Thin driver, which directly converts JDBC calls to database protocols and has best performance without requiring client/server software.

3. Introduction
JDBC or Java Database Connectivity is a specification from Sun
microsystems that provides a standard abstraction(that is API or Protocol) for
java applications to communicate with various databases. It provides the
language with java database connectivity standard. It is used to write
programs required to access databases. JDBC along with the database
driver is capable of accessing databases and spreadsheets. The enterprise
data stored in a relational database(RDB) can be accessed with the help of
JDBC APIs.

Diagrams, Advantages & Disadvantages

6. JDBC Drivers
JDBC Driver is a software component that enables java
application to interact with the database. There are 4 types
of JDBC drivers:
1. JDBC-ODBC bridge driver
2. Native-API driver (partially java driver)
3. Network Protocol driver (fully java driver)
4. Thin driver (fully java driver)

7. JDBC-ODBC Bridge Driver
The JDBC-ODBC bridge driver uses ODBC driver to connect
to the database. The JDBC-ODBC bridge driver converts
JDBC method calls into the ODBC function calls. This is now
discouraged because of thin driver.
Oracle does not support the JDBC-ODBC Bridge from Java
8. Oracle recommends that you use JDBC drivers provided
by the vendor of your database instead of the JDBC-ODBC
Bridge.

8. JDBC-ODBC Bridge Driver
Advantages:
1. easy to use.
2. can be easily connected to any database.
Disadvantages:
1. Performance degraded because JDBC method call is
converted into the ODBC function calls.
2. The ODBC driver needs to be installed on the client
machine.

10. Native-API driver
(partially java driver)
The Native API driver uses the client-side libraries of the
database. The driver converts JDBC method calls into native
calls of the database API. It is not written entirely in java.

11. Native-API driver
(partially java driver)
Advantage:
Performance upgraded than JDBC-ODBC bridge driver.
Disadvantage:
1. The Native driver needs to be installed on the each client
machine.
2. The Vendor client library needs to be installed on client
machine.

(partially java driver)

13. Network Protocol Driver
(fully java driver)
The Network Protocol driver uses middleware (application
server) that converts JDBC calls directly or indirectly into the
vendor-specific database protocol. It is fully written in java.

14. Network Protocol Driver
(fully java driver)
Advantage:
No client side library is required because of application server that can
perform many tasks like auditing, load balancing, logging etc.
Disadvantages:
1. Network support is required on client machine.
2. Requires database-specific coding to be done in the middle tier.
3. Maintenance of Network Protocol driver becomes costly because it
requires database-specific coding to be done in the middle tier.

15. Network Protocol Driver
(fully java driver)

16. Thin Driver
The thin driver converts JDBC calls directly into the vendor-
specific database protocol. That is why it is known as thin
driver. It is fully written in Java language

17. Advantage:
1. Better performance than all other drivers.
2. No software is required at client side or server side.
Disadvantage:
Drivers depend on the Database.
