Question 11 :

How do I create a database connection?

Answer :

The database connection is created in 3 steps:
1. Find a proper database URL (see FAQ on JDBC URL)
2. Load the database driver
3. Ask the Java DriverManager class to open a connection to your database

In java code, the steps are realized in code as follows:
1. Create a properly formatted JDBR URL for your database. (See FAQ on JDBC URL for more information). A JDBC URL has the form jdbc:someSubProtocol://myDatabaseServer/theDatabaseName
2.
try {
Class.forName("my.database.driver");
}
catch(Exception ex)
{
System.err.println("Could not load database driver: " + ex);
}

3. Connection conn = DriverManager.getConnection("a.JDBC.URL", "databaseLogin", "databasePassword");
