A method of generating a database structure from a scanned drawing of a desired database structure, the method comprises the steps of: processing the scanned drawing to identify features of the desired database structure; and implementing the identified features to generate the desired database structure. The drawing is typically hand-drawn. The square shapes represent entities in an Entity-Relationship model and the line(s) represents a relationship in an Entity-Relationship model. Each of the tables has a Primary Key, shown by a key symbol following the text representing the column. Further TABLE C has one and TABLE B has three Foreign Keys, shown by a shaded key symbol following the text representing the column. |
