What skills do programmers need to have?

What skills does a qualified programmer need to master? \x0d\\x0d\Proficient in development tools\x0d\\x0d\As a programmer, be proficient in the use of at least two to three development tools. This is the foundation of a programmer, among which C/C and JAVA are The most recommended development tool, C/C, has become a powerful tool among development tools due to its high efficiency and high flexibility. Many system-level software are still written in C/C. JAVA's cross-platform and good integration with WEB are the advantages of JAVA, and JAVA, its related technology set, JAVA One, is likely to become one of the mainstream development tools in the future. Secondly, it would be better to master a simple visual development tool, such as VB, PowerBuilder, Delphi, and C Builder. These development tools reduce the difficulty of development and can strengthen the concept of the programmer's object model. In addition, you need to master basic scripting languages, such as shell, perl, etc., and at least be able to read these script codes. \x0d\\x0d\Know the database\x0d\\x0d\Why is the database so important? As programmers, they naturally have their own reasons: many applications are centered on database data, and there are many database products. Among them, relational databases are still the mainstream form, so programmers are proficient in at least one or two databases. , you must be very clear about the key elements of relational databases, and you must be proficient in the basic syntax of SQL. Although many database products provide visual database management tools, SQL is the foundation and the universal database operation method. If you do not have access to commercial database systems, it is a good choice to use free database products, such as mySQL, Postgres, etc. \x0d\\x0d\Have a certain understanding of the operating system\x0d\\x0d\The current mainstream operating systems are Windows and Linux/Unix. It is necessary to be proficient in using these operating systems, but these are not enough. To become a true programming master, you need to have an in-depth understanding of the operating system, its memory management mechanism, process/thread scheduling, signals, kernel objects, system calls, protocol stack implementation, etc. As an operating system for developing source code, Linux is a good learning platform. Linux has almost all the characteristics of modern operating systems. Although there is less information on the kernel implementation mechanism of Windows systems, a lot of information can still be obtained through the Internet. Only after you have a certain understanding of the operating system, you will find that you have reached a new level. \x0d\\x0d\Understand the network protocol TCP/IP\x0d\\x0d\ Today, when the Internet is so popular, if you do not have a good grasp of the Internet's supporting protocol TCP/IP protocol stack, you need to quickly make up for it. In this lesson, network technology has changed the mode of software operation, from the earliest client/server structure, to today's WEB Services, to future grid computing, all of which are inseparable from the TCP/IP protocol stack. network protocol support, so it is very necessary to have an in-depth understanding of the TCP/IP protocol. At least, you need to understand the ISO seven-layer protocol model, the principles of common protocols such as IP/UDP/TCP/HTTP, and the three-way handshake mechanism. \x0d\\x0d\Understand the significance of the existence of DCOM/CORBA/XML/WEB Services\x0d\\x0d\With the development of technology, the seamless integration of software and network is an inevitable trend, and the location independence of software systems is the future of computing One of the important features of the model is that DCOM/CORBA is an intermediate platform for the two current mainstream distributed computing. DCOM is an extension of Microsoft COM (Component Object Model), and CORBA is a specification supported by OMG. What programmers need to do is not just to use commercial development platforms to develop software, but to understand the original intention of these technologies, that is, why this technology is needed. If you can understand this, then look back at the specific implementation of these technologies. Just like a cook trying to solve a cow's problem, it can be easily solved.

The importance of XML/WebServices is self-evident. XML is known as the "Esperanto" on the Internet for its structured representation method and super expressive ability, and is one of the cornerstones of distributed computing. \x0d\\x0d\Don't separate software engineering from CMM\x0d\\x0d\In the development of modern large-scale software systems, engineering development control replaces personal heroism and becomes the guarantee for the success of the software system. A programming master is not necessarily Be an excellent programmer. An excellent programmer organically combines excellent programming abilities and development skills with strict software engineering thinking. Programming is only one part of the software life cycle. An excellent programmer should master all aspects of software development. Basic skills at each stage, such as market analysis, feasibility analysis, demand analysis, structural design, detailed design, software testing, etc. One sentence can sum up my opinion: "Unlimited creativity, guaranteed process". \x0d\\x0d\Have strong curiosity\x0d\\x0d\What is the ultimate weapon of a programmer, that is strong curiosity and learning spirit. There is no better weapon than strong curiosity and learning spirit. It is the source and motivation for programmers to reach new heights.
