Database theory: query languages
Algorithms and theory of computation handbook（2010）
摘要
This chapter gives an introduction to the theoretical foundations of query languages for relational databases. It thus addresses a significant part of database theory. Special emphasis is put on the expressive power of query languages and the computational complexity of their associated evaluation and static analysis problems.
