Waterfall-style Model:
Features: Simple.
Insufficient: Require users to make clear and complete requirements at the outset, require more stable user requirements, user participation is not enough, the transfer of information between segments prone to misunderstanding.
Rapid Prototyping Model:
Features: Can compensate the waterfall model user participation is not enough shortcomings;
It can reduce the possibility of omission of user's requirement;
Insufficient: The user is easy to view the prototype as a formal product, too many requirements for the development environment, and requires good cooperation from the user.
Incremental Model:
Features: can quickly submit the finished part of the product, can gradually enhance the product function, the user has enough time to adapt to the new product.
Insufficient: The new part must not destroy the existing system, and should be fully open when designing the architecture.
Spiral Model:
Features: Large-scale software projects for in-house development, facilitates the reuse of existing software, facilitates quality as an important goal, and reduces the risk of excessive testing or inadequate testing.
Object-oriented development model:
Features: The non-linear mode of operation, the gradual evolution of the class and its structure as the expression unit of the system; The development model supports the reuse of software.
