According to this modeling technique, this table has five columns. The entries in row 0 are initialized with the labels Create, Read, Update and Delete. The entries in column 0 contain transaction names. The other entries contain zero or more object class (or entity type) names. To graphically separate row 0 and column 0 from the rest of the table, the initial table separates them by a dual line. The editor does not check for that layout, however. For an example see figure 7.5. The editor checks the immediately and soft constraints of figure 7.6.
