Tang Chenglin: publicly available information is limited. At present, it is known only that Tang Chenglin is the author of SQL Server Database Instance Tutorial, a work catalogued in the library under general computer science. Judging from the title, the book is likely to focus on the practical operation of SQL Server databases, using worked examples as its main approach and addressing learners who need to master basic database concepts and applied skills. Tutorials of this kind typically emphasize step-by-step operations and case exercises, helping readers understand database installation, querying, management, and maintenance through hands-on practice. Since no other background information about the author has appeared in public channels, a full assessment of Tang Chenglin's writing style and academic context is difficult. Based on the existing work, however, Tang Chenglin's writing centers on introductory and practical training in computer database technology, making the book suitable as a reference for related courses or self-study.
