This article discloses the concept of relational database features, such as data value and data type, that may be used as a lexical set to characterize the relevant structure of any database which can be viewed as relational in nature, i.e., as a collection of tables which consist of columns and rows. These relational features provide a mechanism for mapping general natural-language terms (English in the case under discussion) into corresponding formal database query language. The invention makes it possible to write a grammar independent of the database, eliminates the need for customizing grammars for each new application, and opens the way for dictionary construction by database users.
