This package provides several classes that implement different aspects of the access using a central class to manage connections to the MySQL database server.
The DBManager class keeps track of each database connection that is opened. It provides a function named getDB() that establishes the database conection when it is called for the first time, and returned a reference to an object that knows how to handle the connection. When the getDB() function is called again, it returns the same object that previously opened the database connection.
Other classes of this package provide means to execute SQL queries and retrieve query results. |
