JDBC Driver Types:
Why Should We Use JDBC?
JDBC-ODBC Bridge Driver
Why Should We Use JDBC?
- Before JDBC, ODBC API was used to connect and execute the query with the database.
- The ODBC API used an ODBC driver which is written in C language (platform-dependent and unsecured).
- Java has defined its own API (JDBC API) that uses JDBC drivers (written in Java language).
JDBC-ODBC Bridge Driver
- It is used ODBC driver to connect to the database.
- ODBC stands for Open Data Base Connectivity
- The JDBC-ODBC bridge driver mapping JDBC method calls into the ODBC methods calls.
- Note:
- In Java 8, the JDBC-ODBC Bridge has been removed.
- Oracle does not support the JDBC-ODBC Bridge from Java 8.
- Advantages:
- Easy to understand.
- Easy to connect with database.
- Disadvantages:
- Performance degraded because mapping process.
- The client machine needs to install ODBC driver.
- It is used the client-side libraries of the database.
- The driver mapping JDBC method calls into native calls.
- It is partially written in java.
- Advantage:
- It is good compared to JDBC-ODBC bridge driver.
- Disadvantage:
- The client machine needs to install Native driver.
- It is used middleware.
- The middleware server mapping JDBC calls directly or indirectly into the vendor-specific database protocol.
- It is entirely written in java.
- Advantage:
- No client-side library is required.
- The middleware server that can perform many tasks like auditing, load balancing, logging etc.
- Disadvantages:
- Network support is required on the client machine.
- Requires database-specific coding to be done in the middleware server.
- Maintenance becomes costly because it needs database-specific coding in the middleware server.
- This driver mapping JDBC calls directly into the vendor-specific driver.
- It is entirely written in Java.
- Advantage:
- Better performance than all other drivers.
- No software is required at client side or server side.
- Disadvantage:
- Drivers depend on the Database.
