Each connection corresponds to a thread A network socket corresponds to a processing thread, and the socket uses a blocking I/O model; This model is a common strategy for small programs and Java, and is often used for interactive long connection applications (such as BBS), and also for internal server interaction models. This strategy is difficult to meet the requirements of high-performance programs, the

Personal reconstruction version of the computer room charge system needs to re-design the database, then how to design the database? This is also our self-examination in an important course "database principle", for the students who have already benefited from this subject, can be used to learn directly. I took this book in October this year, so let's practice it first. Originally seen in the Jiang Jianling teacher's video, which focuses on the database inside the specific operation, there is no
