- Suppose that you are given the following information for the articles publications: • Each article is published in a Journal only. Article may have their own identification number, name, and any other relevant information. Articles cannot be duplicated and will be only accepted in a Journal. Journal will have their identification number, name, any other relevant information. • Authors may publish one or more articles at a time, but each article must be distinctive and published in the appropriate journal. If necessary, the author may be required to present their work at a specific conference. The details of the conference must also be recorded. A reviewer will examine an article before it is published. Each reviewer is only allowed to review two articles from the same journal.

- Let's apply our knowledge to a scenario that illustrates student registration: Each year, students of an academic institution register for classes in their respective programs. The students use an online university registration system to obtain information about the classes offered. This system also stores other student data. University administrators in charge of registration are on hand to advise students on their course selection. The online registration system requires additional hardware and software to maintain security of the system and to manage the constant student access during the registration period. Some students may still opt to use paper forms for their registration.
