摘要：
XQL an extensible query language system, a nonprocedural language based on the relational algebra is presented. The expressive power of XQL is particularly useful to library application in the sense that information about books of closely related fields can usually be retrieved with a very simple and imprecise query. The implementation of a database skeleton generator for automatically generating conceptual schemas and relational schemas is described.
