Oracle will have oracle native api. Also, use of this driver leads to other installation dependencies; for example, ODBC must be installed on the computer having the driver and the database must support an ODBC driver. The Java program connects directly to the database, meaning that if there is a problem, it will be captured entirely within the JVM of the program making the connection type 1, it’s in the ODBC layer, type 2 it’s in the native compiled code, type 3 it’s in the remote network proxy.

For example, using JDBC drivers enable you to open database connections and to interact with it by sending SQL or database commands then receiving results with Java. Coming to type of drivers, well its different ways in which they interact with DB which classifies them but ultimately aim is same i.

In contrast, a Type 3 driver is a single JDBC driver used to access a middleware server, which, in turn, makes the jdbc net pure java calls to the database. The ;ure then translates the request to the database. Detect and predict anomalies by automating machine learning to achieve higher asset uptime and maximized yield.
Coming to type of drivers, well its different ways in which they interact with DB which classifies them but ultimately aim is same i. Jdbc net pure java tests the drivers by calling the method Driver. Type 1 drivers also don’t support the complete Java command set and are het by the functionality of the ODBC driver.

The different types of jdbc drivers are: The type 3 driver typically provides support for features such as caching connections, query results, and so onload balancing, and advanced system administration such as logging and auditing.
This provides better performance jdbc net pure java the type 1 and type 2 drivers as it does not have the overhead of conversion of calls into ODBC or database API calls. Connect to your application with enterprise level JDBC connectivity. Provides you apis to query data in DB and needs a DB connection to do that which is where driver helps.
