An Entity Relationship (ER) Diagram is a type of flowchart that illustrates how “entities” such as people, objects or concepts relate to each other within a system. Consider the following description of a system: A university registrar’s office maintains data about following entities: Courses, including number, title, credits, syllabus, and prerequisites. Course offerings, including course number, year, semester, section number, instructor, timings and classroom. Students, including student-id, name, and program. Instructors, including identification number, name, department, and title. Furthermore, the enrollment of students in courses and grades awarded to students in each course they are enrolled for must be appropriately modeled. Construct an ER Diagram for the registrar’s office. Document all assumptions that you make about the mapping constraints.
Learning Objective PI3.2 Understand the process of entity-relationship modeling. STEP 1: Background It is very important that you understand the connections among entities, attributes, and relationships. This section has defined each of these terms for you. Typically, entities are described by their attributes, and they are related to other entities. For example, if "student name" is the entity, then age, gender, country of origin, marital status, and other demographic data are the attributes (characteristics) of that particular student. That student is also related to other entities such as financial information, major, and course information. STEP 2: Activity An entity-relationship model is one of the most challenging aspects of designing a database because you have to (1) understand the rules that govern how processes work and (2) be able to define and describe these rules in a picture. This section has provided you with the necessary tools to draw a basic ER model. Imagine the…

Design the UML class diagram to support the system below and upload a picture of your diagram. Used Class Material Website: You are designing a website where students can resale their used material for a course. A course may have multiple sections. The course material is specific to each section of a class. Not all course may require class materials, but they may require many of them. A student can have many used materials for sale. The class material can be either: · Textbook: which has a price(mandatory), title(mandatory), authors(optional), edition(optional) · Software: which has a price(mandatory), title(mandatory), publisher(optional), and also its operating system (mandatory) · Equipment: which has a price(mandatory), title(mandatory), description(mandatory) All class material can be either available or sold.

Generate an Activity UMLdiagram that starts with the customer connecting with the web site and ends with the order available for pickup or ready for delivery. This should be a very focused and specific UML Activity diagram. Note that the workers will also interact with the process at some point - identify the step or steps where the workers interact with the system. The activity diagram must contain a minimum of 15 elements. *** Number each element of the activity diagram. ***
