Database systems are increasingly used in an interactive mode. Users often have insufficient knowledge of suitable query conditions and end up retrieving too many answers or no answers at all. With no help from a database system, query formulation becomes a trial and error process. This can be a frustrating experience and is indeed quite common; the number of empty answers in one of the genomic databases has been reported to reach 38% of all queries asked in that database.

数据库系统越来越多地以交互模式使用。用户通常对合适的查询条件缺乏了解，最终检索到太多的答案或根本没有答案。在没有数据库系统的帮助下，查询公式成为一个反复尝试的过程。这可能是一种令人沮丧的经历，而且确实很常见；据报道，在一个基因组数据库中，空答案的数量达到了该数据库中所有查询的38%。
