ABSTRACT

Object oriented programming methodology is heavily used in the industry to develop complex systems with proven success. The OOP principles are based on solid research in the field of software engineering and system development.

This assignment will enable you to develop an understanding of the principles of object oriented programming as an underpinning technological concept in the field of programming, data management and systems development. You will be able to apply object oriented paradigm in system development and test the robustness an accuracy of the system with reflections on the processes and outcomes.

1.0 – INTRODUCTION:

The purpose of this report is to discuss the principles, characteristics and features of object oriented programming using graphical and practical implementation of a banking application which will be operated by the bank cashiers.

Will be identified objects, data and file structure to implement the design making use of diagrams.

An implementation of the design will be provided to demonstrate how the system works and also will be provided solutions to problems that may occur.

Also the design will be analysed and tested to ensure that system runs without error or bugs ensuring that a good solution is provided.

• Bank Account is a class that provides variables and methods that can be inherited by all the different accounts types which each one are classified as subclasses.

• Polymorphism can be presented in all the 5 types of bank accounts, each one behaves and provide transactions that can be unique or common to other account types.

• Current and Business Accounts present specific variables and methods that can provide a wider range of transactions and possibilities than Savings, ISA and Child Accounts.

• Savings account can do most of transactions but presents some limitations, such as no credit card, loans and or overdraft are not applicable and some of the methods are not available, however it can provide interest.

• ISA and Child Accounts are accounts which an agreement is made that money cannot be withdrawn before the end of terms and conditions of the agreement. They are very basic accounts and do not provide overdraft, credit cards, loans, however they can also provide interest as savings accounts.

• In order to develop the system it was adopted Adaptive Planning in which the requirements were added during the development process.
