  • Patent number: 5471613
    Abstract: A system, program and method for graphically representing a WHERE or HAVING clause of an SQL query directed to a relational database. Logical operators are defined and linked to predicates using a tree structure format. The tree is not binary in character and consequently exhibits a 1:1 relation between the predicates and tree leaves. The tree structure representation provides intuitive feedback to the user defining the query. Preferably the SQL format and tree structure graphic format queries appear simultaneously on the video display of the computer system used to define the query.
