Analysis should be performed on the programming process to establish a JDBC connection and includes

importing the JDBC packages using import statements in the Java program to import the related Java classes
registering the JDBC driver to instruct the JVM to load the driver into memory so JDBC requests can be performed
creating database URL notation by creating a properly formatted URL address so the database can connect, such as in the following example:

getConnection(String url)
getConnection(String url, String user, String password)

creating a connection object by programming a call to the DriverManager object’s getConnection() method to establish the actual database connection. The most commonly used form of getConnection() requires you to pass a database URL, a username, and a password
establishing a port-addressing connection, such as in the following summary and complete examples:

(Summary)

jdbc:oracle:thin:@jdoe:1511:EMP URL Connection: DriverManager.getConnection(String url, Properties info);

(Complete)

import java.util.*;

String URL = "jdbc:oracle:thin:@jdoe:1511:EMP";
Properties info = new Properties( );
info.put( "user", "username" );
info.put( "password", "password" );

Connection conn = DriverManager.getConnection(URL, info);
