What is software system architecture?

C/S (client/server) structure, the so-called client/server structure. It is a software system architecture, through which we can make full use of the advantages of the hardware environment at both ends, reasonably allocate tasks to the client and server, and reduce the communication overhead of the system. At present, most application software systems are two-tier structure in the form of client/server. As the current software application system is developing to a distributed Web application, both Web and client/server applications can perform the same business processing and use different modules to share logical components. Therefore, both internal and external users can access new and existing application systems, and the new application system can be extended through the logic in the existing application system. This is also the development direction of the current application system.

B/S (Browser/Server) structure is a browser and server structure. It is a change or improvement of C/S structure with the rise of Internet technology. Under this structure, the user interface is realized through the WWW browser, and very little transaction logic is realized in the browser, while the main transaction logic is realized in the server, forming a so-called three-tier and three-tier structure. This greatly simplifies the load of client computers, reduces the cost and workload of system maintenance and upgrade, and reduces the total cost (TCO) of users. According to the current technology, it is relatively easy to master and low cost to establish a network application program with B/S structure in local area network and apply it through the database of Internet/Intranet mode. It is a one-time development, which enables different people to access and operate the same database from different places in different access ways (such as LAN, WAN, Internet/Intranet, etc.). ). It can effectively protect the data platform and management access rights, and the server database is also very secure. Especially after the emergence of cross-platform languages such as JAVA, the management software based on B/S architecture is more convenient, fast and efficient.
