Connecting to the Database

• Decouple connection management from the other database code
• We supply a SimpleDataSource class to do this
• Call its static init method with the name of the database configuration file

  SimpleDataSource.init("database.properties");

• Configuration file is a text file containing four lines

  jdbc.driver= . . .
  jdbc.url= . . .
  jdbc.username= . . .
  jdbc.password= . . .
