常建功

Chang Jiangong is an author of Chinese computer technology books, about whom publicly available information is limited and whose life and educational background have not been systematically recorded. Judging from the two works held in the collection, his writing addresses two kinds of readers: database administrators and programming beginners. Oracle Database Management and Maintenance in Practice deals with the day-to-day management and maintenance of Oracle databases and is a technical reference that emphasizes practical operation, while the five-volume Zero-Basis Programming Series is aimed at readers with no programming experience and introduces the fundamentals of programming in separate volumes. The two works fall under the general categories of computer science and programming design, and together they reflect a practical, step-by-step approach suited to readers who prefer to learn by doing.
