The Java Database Connect API (JDBC) is supported by all major database vendors as well as many small databases. It all depends on what database platform you are trying to connect to.

The type 1 driver, JDBC-ODBC Bridge, translates all JDBC calls into ODBC (Open DataBase Connectivity) calls and sends them to the ODBC driver.The performance is degraded since the JDBC call goes through the bridge to the ODBC driver, then to the native database connectivity interface. The result comes back through the reverse process. Considering the performance issue, type 1 drivers may ... |
David, most of my experience with relational databases is with Oracle. Oracle supplies two types of JDBC drivers, OCI and Thin. Since the OCI driver is a Type II driver, that makes use of native code, it might be natural to assume that it would give better performance than the Thin driver. My experience, however, is quite the opposite, especially if ... |

Hi all developers, We generally go for the database application by first finalising whether we will use Oracle or SQL,etc.Then accordingly we write the statements for connection,statement,resultset etc. When it comes to shift of RDBMS we have to make changes to actual code of all the classes that communicate with the database.A friend of mine in the office has suggested writing ... |
The first step to using a database in java is a call to: Class.forName("driver name"); or Class.forName("driver name").newInstance(); Now, my understanding is that this is so that a static block in the driver can register the driver so that a call to DriverManager.getConnection knows which driver to call without the user having to hard code it. My question is: is there ... |
The native-protocol/all-Java driver (JDBC driver type 4) converts JDBC calls into the vendor-specific database management system protocol so that client applications can communicate directly with the database server. These Drivers are completely implemented in Java to achieve platform independence and eliminate deployment administration issues.

chitra The registerDriver method is for the Driver class itself to call.

Other than Class.forName() the ... |

Not quite the right question. In 'microsoft land', there is a generic way to connect to databses via 'Open Database Connectivity' (ODBC).

Java has a similar concept - JDBC (which ... |
