Figure h1.1.6 Implementation (realization): Hollow arrow and dashed line representationThe example ( figure I) relationship specifies a contract between two entities. In other words, one entity defines one contract and the other guarantees the performance of the contract. When modeling a Java application, the implementation relationship can be expressed directly with the implements k

in Java. The difference between Association and aggregation is purely conceptual and strictly reflected in semantics. Aggregation also implies that there is no loop in the instance diagram. In other words, it can only be a unidirectional link. Figure F Composition) Synthesize (Figure G) Is a special form of aggregation, suggesting that "local" is responsible for the lifetime of the "whole. Synthesis is not shared. Therefore, although local data may

The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, the Unified Modeling Language). This course aims to show the highlights of UML. There are nine types of modeling icons in UML: Use case diagram

A sequence diagram describes the chronological order in which messages are sent between objects, and is used to represent the order of behavior in a use case. sequence

example, the candidate objects include customer and order. Therefore, the customer class and order class models are constructed in the class diagram. These may be traditional object-oriented classes, or non-object-oriented classes such as ASP pages, database tables, or COM + components. The UML class represents a rectangle, as shown in 3-6. The figure shows that this class has some attributes (customerid
