Please help me do the schema of this ERD The diagram represents an Entity-Relationship (ER) model depicting a university course management system. It includes the following entities and relationships:1. **Entities**: - **Student**: Attributes include `s_id`, `First`, `Last`, and `phone`. - **Course**: Attribute is `c_id`. - **Section**: Attributes include `s_id` and `no_of_students`. - **Semester**: Attributes include `Year` and `semester`. - **Professor**: Attributes include `SSN` and `Name`.2. **Relationships**: - **Take**: Relationship between `Student` and `Course`. Each student can take multiple courses. Each course can have multiple students. The `Grade` is an attribute of the `take` relationship. - **Have**: Relationship between `Course` and `Section`. Each course can have multiple sections, but each section belongs to only one course. - **Teach**: Relationship between `Professor` and `Section`. A professor can teach multiple sections, and each section can be taught by multiple professors.**Attributes**:- Entity attributes are represented by ovals. Each entity has a unique identifier, highlighted as underlined attributes such as `s_id` for Student and `c_id` for Course.**Cardinality Notations**:- 1,1 or 1,N indicates a one-to-one or one-to-many relationship, respectively.- 0,N indicates zero-to-many relationships, allowing flexibility in associations.This ER model is designed to capture the essential components of academic course administration, illustrating how students, courses, professors, and semesters are interrelated.

Hi, I could use help on making ERD's for this problem. It needs to be crows-foot notation. It must have entities, attributes, relationships, cardinalities, primary keys, and foreign keys. Please break this down so I can make sure I understand. Here is the description: Marsha Mobley, the manager of the ACME Anime Shop wants you to design a database system that will enable a number of tasks. One problem that Marsha has is keeping track of inventory. Several times a week the store receives shipments from various vendors. Marsha would like a system that can record these shipments. Most of the shipment information originates with an order to the vendor.Marsha currently records order information on an order form, which is shown below, along with the form currently used to record inventory. When shipments arrive, Marsha wants the system to indicate that the order has been received. More importantly, Marshaneeds the system to update the store inventory. The system should also record basic…
