"Credits and deposits.
To add credit to an account by bringing cash to a bank in person, the account holder can fill a small credit slip or deposit slip. The total amount of each note and coin is counted and entered on the slip, along with who it is paid in by and the date. The cash and details are counted and checked by the teller at the bank, if everything is in order the deposit is credited to the account, the credit slip is then kept by the bank and the credit slip booklet is stamped with the date and then returned to the account holder.An account holder uses their passbook to record their history of transactions with their bank."

"A very important concept in object-oriented design, inheritance, refers to the ability of one class (child class) to inherit the identical functionality of another class (super class), and then add new functionality of its own. (In a very non-technical sense, imagine that I inherited my mother's general musical abilities, but in my family I'm the only one who plays electric guitar.) To model inheritance on a class diagram, a solid line is drawn from the child class (the class inheriting the behavior) with a closed, unfilled arrowhead (or triangle) pointing to the super class. Consider types of bank accounts: Figure 4 shows how both CheckingAccount and SavingsAccount classes inherit from the BankAccount class.
Figure 4: Inheritance is indicated by a solid line with a closed, unfilled arrowhead pointing at the super class." [ibm.com/ developerworks/ rational/ library/ content/ RationalEdge/ sep04/ bell/ index.html]
