Table:
A table is a logical structure that represents an entity state. It is one of the components of database.
One to Many Relationship:
When one record in a database table is associated with more than one record in another table, the relationship between the two tables is referred as one to many relationship. It is also represented as1: M relationship. This is the opposite of many to one relationship.
CROW FOOT ERD:

- Hi, can you help me with this question? I have an exam coming up, and I'm using the book problems to study. The manager of a consulting firm has asked you to evaluate a database that contains the table structure shown in Table P6.10. (This should be attached). Table P6.10 was created to enable the manager to match clients with consultants. The objective is to match a client within a given region with a consultant in that region and to make sure that the client's need for specific consulting services is properly matched to the consultant's expertise. The following basic business rules are maintained: Each client is located in one region. A region can contain many clients. Each consultant can work on many contracts. Each contract might require the services of many consultants. A client can sign more than one contract, but each contract is signed by only on client. Each contract might cover multiple consulting classifications. Each consultant is located in one region. A region can…arrow_forwardSubject: Database Topic: EERD Please use UML Modelling Notation.
