Lastly please describe 3 Ways in which you can validate the model

FIGURE 4-28 WRITER'S PATROL CORRECTION NOTICE Writer's Patrol Traffic Citation A. Draw an E-R data model based on the traffic citation form. Use five entities, create identifiers (watch out for any composite identifiers that may be needed, and you can use surrogate identifiers if appropriate), and use the data items on the form to specify attributes for the entities. Use the IE Crow's Foot E-R model for your E - R diagram. Note that all Correction Notices have as their identifier an identifying number that is not shown in the figure, and have an independent existence whether or not they are filled in. The alternative would be a composite identifier (such as Month, Date, Year, Time). But this is so cumbersome that even without a preexisting NoticeNumber we'd use a surrogate identifier
