Different programming languages have different basic data types depending on their design purposes. Java, C #, and other languages are designed for general application development. The basic data types are string, number, Boolean, and other atomic data types, as well as arrays and common objects. SQL, PowerBuilder, R, and esproc are designed for data processing. The basic data type is a structured two-dimensional data table object. For example, this S

From today on, I will officially write some articles about my graduation design system. I was planning to write some articles before, but I always felt that I was missing some knowledge. After more than two months of accumulation, I gradually formed some ideas. During this period, I completed the development of the debug version of the system, accumulated some experience, and learned a lot. I hope my article will inspire you.
