An abundance of Data Base Management Systems and Query Languages already exist, not to mention those which have been, and continue to be proposed. Most Data Base Management System surveys focus on the type of model used to represent the data, methods of access, protection, etc. This paper acquaints the EDP manager with the fundamental differences among the more significant query languages with emphasis on those characteristics which should be considered when choosing a query language. The term query language as used here has been expanded to include the entire user interface to the data base, and encompasses both data sublanguages and stand-alone query languages.
