if we don't close the connection , it wil lead to connection memory leakage.unless until application server/web server is shut down ,connection wil remain activate even though the user logs out .
General JDBC Architecture consist of two layers: JDBC API - this provides the application to JDBC manager connection. JDBC driver API - this supports the JDBC manager to driver connection.
In a JDBC program connecting to MySQL, you should select the MySQL Connector/J driver. This driver is specifically designed for MySQL database interaction and implements the JDBC API. You can include it in your project by adding the MySQL Connector/J JAR file to your classpath. Once included, you can establish a connection to the MySQL database using the appropriate JDBC URL and credentials.

-Loading the Driver -Establish a Connection -Execute Statements -Get Resultset -Close the database connection
JDBC mean Java Database Connectivity. In java, using JDBC drivers, we can connect to database. Steps to connect to JDBC. 1) Load the driver, using Class.forName(DriverName); 2) Get the connection object, Connection con = Driver.getConnection(loaded driver name); 3) Create a SQL statement, Statement s = con.createStatement(); 4) Create Resultset object using the statement created above, ResultSet rs = s.executeQuery("sql statement"); Iterate the result set to get all the values from the database. Finally don't miss this 5) s.close(); 6) con.close() ;
JDBC Driver Manager is a class that manages a list of database drivers. It matches connection requests from the java application with the proper database driver using communication sub protocol.
JDBC is short for java database connectivity. There are 4 type of JDBC drivers : 1) JDBC-ODBC 2) Native-API 3) JDBC-Net 4) Native-Protocol.
Ans:Loading a class in JDBC For getting connection to database and to query database for INSERT,UPDATE,DELETE and to do some operations on database through java programs you need to load the jdbc driver class for a particular database provided by the database provider for that you use class.forName() Method this method will load the class which are necessary for database operations
When we create a website or a project in programming language we need to use a database for storing the data . A database connection used to establish a connection between the server and the client. For this jdbc jar is added in the project in case of java .
TO connect database two things are require: 1) JDBC driver 2) ognl.jar Using these two we can create a database connection.
