Document Summary
Works well in situations where complicated systems are undergoing continuous maintenance, adaptation and design. The unified modelling language (uml) is an industry standard for modelling object-oriented systems. Recycling of programs parts should reduce the costs of development in computer based systems. Making a change in one object has a minimal impact on other objects. Persons, places or things that are relevant to the system be analysed. May be customers, items, orders and so on. May be gui displays or text areas on a display. Defines the set of shared attributes and behaviours found in each object in the class. Should have a name that differentiates it from all other classes. Instantiate is when an object is created from a class. An attribute described some property that is possessed by all objects of the class. A method is an action that can be requested from any object of the class.
