<s>[INST] Hello, Open Assistant. Could you give a few examples of beginner-friendly topics for a database structure to be created in a Information Systems and Databases course project? Please provide a short list of a couple of entities and relations these database schemas would contain, if at all possible. Thank you! [/INST] I'd be glad to help!  Here are some ideas:
1. Library Management System:
   * Entities: Books, Members, Authors, Publishers, Loans
   * Relations:
       * Books (Book_ID, Title, Author_ID, Publisher_ID, ISBN, Publication_Year, Status)
       * Members (Member_ID, First_Name, Last_Name, Email, Phone_Number, Address)
       * Authors (Author_ID, First_Name, Last_Name, Nationality, Birth_Year)
       * Publishers (Publisher_ID, Name, Address, Phone_Number, Email)
       * Loans (Loan_ID, Book_ID, Member_ID, Loan_Date, Due_Date, Return_Date)
2. Inventory Management System:
   * Entities: Products, Suppliers, Categories, Orders, Order_Items
   * Relations:
        * Products (Product_ID, Name, Category_ID, Supplier_ID, Quantity, Price)
        * Suppliers (Supplier_ID, Name, Address, Phone_Number, Email)
        * Categories (Category_ID, Category_Name, Description)
        * Orders (Order_ID, Supplier_ID, Order_Date, Total_Cost, Status)
        * Order_Items (Order_Item_ID, Order_ID, Product_ID, Quantity, Unit_Price)
3. University Enrollment System:
    * Entities: Students, Courses, Instructors, Departments, Enrollments
    * Relations:
         * Students (Student_ID, First_Name, Last_Name, Email, Birth_Date, Department_ID)
         * Courses (Course_ID, Course_Name, Instructor_ID, Department_ID, Credits)
         * Instructors (Instructor_ID, First_Name, Last_Name, Email, Department_ID)
         * Departments (Department_ID, Department_Name, Building)
         * Enrollments (Enrollment_ID, Student_ID, Course_ID, Semester, Grade)</s>
