Produce an ER Model for the following scenario (presented in Step 1 below) and business need, for the Pythagoras Math Academy. Reference the attached video (Course Project Ph2 Video.mp4), for a full introduction and demonstration and expectations for this project.
Step 1: Read and understand the Scenario and Business needs presented below. Define and document the ENTITIES, and RELATIONSHIPS, required to address the business needs. The nouns in the scenario below will give the ENTITIES that you will need. Finally, the verbs will describe the RELATIONSHIPS.
Scenario and Business Need
The Pythagoras Math Academy is in need to develop a database to keep track and control of his students, teachers, and classes offered.
Teachers are able to teach multiple courses. But they are required to be certified on the course they are teaching. For example, only a group of teachers are certified to teach Algebra, and other Geometry.
Students can take multiple courses. Courses are taught by teachers with the proper certification and have multiple certs as needed. Courses are taught in one of the classrooms at one of the School’s several sites.
Each classroom is optimized to serve the needs for a course (for example some courses might require computer labs and whiteboards). The school needs to keep track of the math courses delivered in each of the sites.
Step 2: For this project, you are required to use MS Visio or ERD PLUS to produce the deliverables.
If you are using MS Visio follow the steps below:
If you are using ERD PLUS.
Step 3: Define and Database ENTITIES
Step 4: ADD the required ENTITY ATTRIBUTES
Step 5: Define RELATIONSHIPS
Step 6: Define CARDINALITY RELATIONSHIP
Set the cardinality for each of your relationships defined in Step 5.
For MS Visio: select a relationship line in the drawing area that is connecting two entities. In the Database Properties window, select the miscellaneous category. Select the cardinality for the selected relationship.
