What is the difference between the object-oriented life cycle model and the traditional life cycle model?

The structure designed with object-oriented idea is readable. Because of the existence of inheritance, even if the requirements change, the maintenance is only in a local module, so it is very convenient to maintain and the cost is very low.

2. High quality

When designing, we can reuse the existing classes that have been tested in the field of previous projects, so that the system can meet the business needs and have high quality.

3, high efficiency

In software development, according to the needs of design, things in the real world are abstracted and classes are generated. Solving problems in this way, close to daily life and natural way of thinking, is bound to improve the efficiency and quality of software development.

4, easy to expand

Due to the characteristics of inheritance, encapsulation and polymorphism, the system structure with high cohesion and low coupling is naturally designed, which makes the system more flexible, easier to expand and lower in cost.
