Answer / A. Vinoth Saravanan

To connect to a database in Java using JDBC, you need to follow these steps:
1. Load the JDBC driver class.
2. Establish a connection with the database using the DriverManager or DataSource.
3. Send SQL queries and process the results.

I have the choice of manipulating database data using a byte[] or a java.sql.blob. Which has best performance?
