比较了几种用户友好的图形数据库查询语言，它们允许用户通过在屏幕上指定图形辅助示例来制定查询。描述了最早的这种语言之一，M.M.Zloof(1977)的Query-by-Example。所讨论的其他语言包括用于统计和科学数据库的按示例聚集、按示例汇总和按统计关系表查询；用于历史数据库的按示例时间查询；用于关系、网络和分层数据库的按示例通用查询；用于办公环境的按示例办公室、自然形式查询语言ForManager和企业系统自动化；以及用于图片(图像)数据库的图片查询和按图片示例查询。讨论了在每种语言中使用的基本特征、查询规范和解释、对象操作、查询语言结构和查询处理技术。
Several user-friendly graphical database query languages that let users formulate a query by specifying a graphically aided example on the screen are compared. One of the earliest such languages, M.M. Zloof's (1977) Query-by-Example, is described. Other languages discussed are Aggregates-by-Example, Summary-Table-by-Example, and Query-by-Statistical-Relational-Table for statistical and scientific databases; Time-by-Example for historical databases; Generalized-Query-by-Example for relational, network, and hierarchical databases; Office-by-Example, Formanager, the Natural Forms Query Language, and System-for-Business-Automation for office environments; and Picquery and Query-by-Pictorial-Example for pictorial (image) databases. The basic features, query specification and interpretation, object manipulation, query language constructs, and query processing techniques used in each of the languages are discussed.<<ETX>>
