a. Convert the ER diagram into a relational database schema. Be certain to indicate primary keys (underline).
Eg. Student (StudentID:text: Student_name:text,.....)
NB: You are required to identify many-to-many relationships in the ER diagram and include Associative / Bridge entities.

The following figure shows an ER schema for a database that can be used to keep track of transport ships and their locations for maritime authorities. Map this schema into a relational schema and specify all primary keys and foreign keys. Use arrows to specify the relationships. Use descriptive names for foreign keys.
This is symbolized by a circle over a single line in an entity relationship diagram. It signifies that the supertype does NOT have to be one of the specified subtypes. Partial completeness Total completeness System completeness Associative completeness A supertype entity can contain as many as ____ subtype entities. 10 1 100 no defined limit When you set up an Entity Relationship Diagram, and have a many-to-many relationship, this entity is created to avoid problems inherent to a many-to-many relationship....
Written Assignment#1: Preliminary Database Design Preliminary Database Design The purpose of this project is to give you some experience in database design. We will explore both theoretical and practical aspects of the database design steps. Once you master it well, it is a simple matter of translating the theoretical concepts you developed into the terms of a concrete DBMS to implement the database. Conceptual/Logical Database Design You must choose some facet of real life that you feel needs to be...
2. The following figure shows an ER schema for a university database. a) Map this schema into a relational schema b)Show the SQL statements needed to create the relations, using proper constraints.

A University database contains information about students (identified by social security number, or SSN) and courses (identified by courseid). Students enroll in courses; each of the following situations concerns the Enrolls-In relationship set. For each situation, draw an ER diagram that describes it (assuming no further constraints hold). 1.Students can enroll in the same course in several semesters, and each offering must be recorded. 2. Students can enroll in the same course in several semesters, and only the most recent...
Help with database creation - create a visio ER diagram of the
scenerio below.. thanks
The registrar's office at Weber State University wants you to create a new database to support an future application that will help their department better keep track of the scheduled classes offered each semester, including the specific course sections and lecturers appearing in the schedule, and the students registering for courses according to the published schedule. Courses (think course catalog) may or may not be...

Would you please help me with this homework ?
1- Explain what requirements this ER diagram is implementing
2- Draw an ER diagram (relationships) for the following business
rules in a company:
• A salesperson manages one or many other salespeople while a
salesperson is managed by only one salespeople.
• A salesperson can be an agent for many customers but a customer
is managed by only one salesperson.
• A customer can place many orders. But an order can...
Q1.a) Based on the business rules, you are expected to construct
an Entity-Relationship (ER) diagram. The ER diagram should include
entities, attributes (if there are less than three specified in the
business statements, please add some extra attributes), identifiers
and corresponding data types, the relationships among entities with
cardinality and associative entities.
.b) Extend Q1.a) to apply generalization/specialization
technique to construct an Enhanced-ER (EER) diagram. The EER
diagram should specify the complete (total) and disjoint
(mutuallyexclusive) constraints on the
generalization/specialization....
DATABASE SYSTEMS Project INDIVIDUAL WORK DELIVERABLE #: SUBMISSION DATE No Group Work Allowed April 8 Introduction to Coursework You have been approached by a University for the design and implementation of a relational database system that will provide information on the courses it offers, the academic departments that run the courses, the academic staff and the enrolled students. The system will be used mainly by the students and the academic staff. The requirement collection and analysis phase of the database...
