Abstract
A user interface for creating or changing the structure of a relational database having multiple tables linked by keys and arranged by indices. In one form, the invention contemplates the juxtaposed depiction on a computer video display of a matrix defining the structure of a table with one or more matrices defining the linking relationships between selected columns from that and related tables. Selection and movement through the data structure is accomplished by mouse actuated cursor. Referential integrity among the database tables is maintained through the use of primary and foreign keys. The relationships of the keys and indices to the columns of the tables are clearly represented in matrix format windows which appear concurrently with table column property information.
