| 词条 | Ambiguous viewpoint |
| 释义 |
Object Oriented Analysis and Design models are often presented without clarifying the viewpoint represented by the model. By default, these models denote an implementation viewpoint that visualises the structure of a computer program. Mixed viewpoints do not support the fundamental separation of interfaces from implementation details, which is one of the primary benefits of the object-oriented paradigm. In Object Oriented Analysis and Design there are three viewpoints: The business viewpoint (the information that is domain specific and matters to the end user), the specification viewpoint (which defines the exposed interface elements of a class), and the implementation viewpoint (which deals with the actual internal implementation of the class).[1] If the viewpoint becomes mixed then these elements will blend together in a way which makes it difficult to separate out and maintain the internals of an object without changing the interface, one of the core tenets of Object Oriented Analysis and Design.[1] See also
