Explanation of Solution
Relational Diagram:
- A relational diagram refers to a visual representation of the relational
database ’s entities, the relationships between those entities, and the attributes within those entities. - Therefore, it makes it easy to understand what the entities represent, what types of relationships exist and how these relationships are implemented.
Example of Relational Diagram:
- The relational diagram given below shows the connecting fields that is, “AGENT_CODE” through 1:M relationship type.
- To illustrate simple relational diagrams, use MS Access, Database tools, and “relationships” options on the main Access menu...

Create a diagram for a database with at least 5 tables. This should show your table names and column names. Show the relationships between
the tables. Write a statement explaining your database design (why did you use the tables that you did).
Create a database in Access based on your diagram. Include all tables in your diagram. Tables should each have a minimum of 5 rows.
Create 5 SQL statements using your database. At least 2 of these should be manipulation statements (insert, update, etc). The others should
be select statements. Explain what your sql statements do and how they would be useful to your database.

(Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows: PATRON table records a patron’s ID, name, address, phone number, and email address. BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book. BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table.
