Read Chapters 4, 10, & 12 (files uploaded). Based on the Computer Publishing, Inc. (file uploaded), perform the following tasks: 1. Use the Violet UML editor to create 1 class diagram that represents the book, its key content elements, and related product content. Include related product content, such as a set of PowerPoint slides, an electronic book formatted as a Web site or PDF file, and a Web-based test bank. Select 1 appropriate class diagram from the Class Diagram examples (file uploaded). Take a screen shot, copy it into a Word document. Save the Class Diagram Violet UML file, and send it to me into zipped folder. 2. Identify the data types required to store content of the book, slides, and Web sites. Are the relational DBMS data types listed in Figure 12-14 (file uploaded) sufficient? Why? 3. Authors and editors are often independent contractors, not publishing company employees. Consider the implications of this fact for controls and security. How would you enable authors and editors to interact with the database? How would you protect database content from hackers and other unauthorized accesses? -Violet UML editor download link: https://sourceforge.net/projects/violet/ Note: Do not write introduction & conclusion.
