Object-Oriented Analysis Design learning and exploration (6): Object-oriented disaster (OO catastrophe)

only one change point (every class shocould attempt to make sure that it has only one reason to this, the death of each badly designed piece of software .) What remains unchanged in the software is changes. Poor design will cause the software to crash in changes, but good software can be easily changed. Each type has only one reason for change, which will make your software relatively simple to cope with changes. In other words, reduce the change

Object-Oriented Analysis Design learning and exploration (6): good design = software flexibility (good design = flexible software)

a good software design is to try to change If your software is hard to change, the problem may occur when you want to improve the design. Now let's see if several instruments can be easily changed. If a new instrument is added to an existing program, we need to add a new instrument specification and add a new query method to inventory, which does not seem easy to change! It seems that we still ha

computing problems. But the method of gradual refinement cannot provide a system strategy or method to solve a specific problem. Sometimes, there is no top-down method for some problems. Structured program analysis is an effective method for small-scale programs, but it is often ineffective to promote it to large-scale system development, developers cannot use this method to easily reuse reusable components of previous programs. The abstract mechanis

method to grasp complexity is to break it into smaller parts when designing a complex software system, and then refine them separately. AlgorithmDecomposition represents each module in the system as the main step in a general process. Object-oriented decomposition is used to break down the system based on the key abstraction in the problem field. The algorithm decomposition method highlights the sorting o
