Abstract
A method, apparatus, and article of manufacture which provides for visually depicting join relationships in a database management system. The method comprises the steps of visually depicting join relationships on a monitor coupled to a computer and receiving a join command from a user input device into the computer, wherein the join command selectively chooses a join relationship. The join relationships are visually depicted in a window displaying matching records in a first table joined to matching records in a second table, all records in a first table joined to matching records in a second table, and matching records in a first table joined to all records in a second table.
