Auto Load Class
Many developers write object-oriented applications, creating a PHP source file for each class definition. A very big
Annoyance is having to write a long list of included files at the beginning of each script (one file per class).
In a software development system, it is not possible to write all the classes in a PHP file, when in a PHP file
When you need to invoke a class declared in another
The difference between an outline design and a detailed design
Summary design is the design of the software structure, including the composition of the module, the hierarchy of modules, module call relations, the function of each module and so on. At the same time, it is nec

I. Introduction
When using the ORM framework, a table must have a primary key. If there is no primary key, there is no way to update a record uniquely. It is easy to set a self-increasing primary key in the SQL Server database and MySQL database. It is complicated to set a self-increasing primary key in the Oracle database. This article does not discuss the auto-growth of a single table in the database. It discusses the

To develop a user-satisfied software is not easy, the software architect must fully grasp the various requirements, balance the need for potential contradictions between the needs of different categories to meet. From the understanding of the complexity of requirements, this paper demonstrates how to design the architecture of different requirements through RUP's
