Assessment Details
Kids e-Books is a company that specialises in loaning children’s e-books to the general public, schools, kindergartens and play groups. Kids e-Books can own several copies (BOOKCOPY) of each book (BOOK). For example, Kids e-Books may have 10 copies of the book: Where is the green sheep? In the database, the book: Where is the green sheep? would be one BOOK, and each copy would be a BOOKCOPY. A borrow transaction (BORROW) involves one or more copies being lent to a member (MEMBERSHIP). A copy can be loaned many times over its lifetime; therefore, there is an M:N relationship between BORROW and BORROWCOPY. DETAILBORROW is the bridge table to resolve this relationship.

1. Design your ER Diagram with all entity names, attribute names, primary and foreign keys, relationships, cardinality and participation indicated. You may add entities or attributes as you see fit. You will need to normalise all of your entities, to resolve any many to many relationships.
• Your attribute names, primary and foreign keys should be indicated as per the conventions given in the lecture slides (i.e., entity/table names in capitals, attributes as proper nouns, primary key underlined and foreign keys in italics).
• All many to many relationships should be resolved, and you should include a discussion of normalisation including the normal form that each entity is in and why that is optimal. Also, a discussion of how normalisation was achieved for that entity.
2. For each entity, create some example data for that entity. Include 5 rows of data for each entity.
3. Write the SQL code to create the table structures from your developed ERD. The structures should contain the attributes specified in your ERD. Use data types that are appropriate for the data that will need to be stored in each attribute. Enforce primary key and foreign key constraints as indicated by your ERD.
4. Write the SQL code to insert your data from (2) into the SQL table structures
Documentation Requirements
1. Prepare a business style report which contains the following:
a) ER diagram based on defined scenario
b) Example data
c) A copy of your SQL code
d) Statement of any resources used. These includes full disclosure of assistance from all sources including tutors and other students. Full APA referencing of any resources used.
Report file name: ITECH2004_Assignment1_Report_yourname_studentID
