Students who have studied C and Java must know that these two languages represent two different ways of development, namely the structured development method represented by C and the object-oriented development method represented by Java. Because the two are very different in the program structure, therefore, in the software development field, according to their own needs to choose a reasonable development mode is particularly important.There are usua
manufacturers, but its development is limited by system integrators. At the same time, it should be noted that some vendors focus on the development platform, and the workflow product level is very general or even preliminary.
3. Provide workflow products and Business Kits/platforms, and connect to projects by yourself. This is a well-established manufacturer, mostly a veteran or with sufficient funds. The business kit/platform can provide users with the greatest value. It is king to directly f
