How would I built this database in access?

STEP 1 Background In this activity, you wi learn how to create Access tables from an existing design. The construction of any database begins with creating its data tables. If you cannot create tables, then you cannot create a database. Even if you use an existing database, knowing where the tables come from will help you understand how you can utilize the database and why it sometimes behaves in ways that you otherwise might not expect. STEP 2- Activity Imagine that you are building a database for your university. The following diagram is called an entity-relationship diagram (ERD). It describes some of your university's data. Specifically, this part of the database stores data related to four entities: Department, Course, Student, and Grade. Dept Course GradeHStudent The lines, or relationships, in the ERD tell us that Each department can have several courses, or it might not have any. Each course belongs to only one department. Each course can have several students, but it might not have any. (This would be a temporary situation when registration starts.) Each student in the course receives one grade. Each student can take several courses, but he or she might not be registered for any (yet) Each course gives that student one grade. Based on this information, it is possible to begin building tables and establishing the relationships
