Currently, various technologies in the Java field are blooming, with a wide range of names. How can we choose these frameworks based on our own needs? Especially for beginners, they are also very confused about the direction of learning. It is even more important to learn based on the characteristics of their projects. Next we will consider the birth of these J2EE/Java EE frameworks from a development perspective, which may be of great help to our selection. First, we need to understand what a h

What I'm sharing is a simplified version of the compilation architecture, and the goal I'm going to achieve is to compile a folder that follows the following organizational structure: Bb_xxx _inc _src Entry ......... Modules Module1 ......... Module2 ......... ......... _SRC directory can be allowed to have a recursive directory or file, the maximum depth of no more than 5,makefile definition rules will go to automatically search all C source files, c

1. Traditional X86 architecture The traditional X86 architecture uses a common CPU and PCI bus interface, which has high flexibility and scalability. It was once the main platform for the development of network security devices. Main advantages:The product features are implemented by software, which is easy to add or reduce function modules and provides good flexibility. However, the shortcomings are also p

business data) has two features: The data architecture is relatively simple, only Mt, Mo, and report (response) are supported. However, MT data has a state transition, that is, to be submitted-> responded-> reported status; second, data has no requirements for transaction processing. The role of the database in the system is to query upstream and downstream SMS records. Therefore, I think it is a good choi
