Assessment/evidence gathering conditions
Each assessment component is recorded as either Competent (C) or Not Yet Competent (NYC). A student can only achieve competence when all assessment components listed under “Purpose of the assessment” section are recorded as competent. Your trainer will give you feedback after the completion of each assessment. A student who is assessed as NYC (Not Yet Competent) is eligible for re-assessment.
Resources required for this assessment
Computer with relevant software applications and access to internet Weekly eLearning notes relevant to the tasks/questions

Part B: Project (40 Marks)
 
PROBLEM DESCRIPTION
A database is to be made to store information about books. Details to be stored for each book will be the title, year of publication, publisher, author(s), and ISBN. Some books may have an edition number. Each publisher will have a name and an optional address.
Publishers produce many books, but each book will have a single publisher. Each author may write several books, and a book may have one or more authors, and authors will be represented by their last name and initials.
Also associated with the books will be keywords from the title, which will form the basis of a search function.

	Example Books: Title: Cryptonomicon Year: 2000 Publisher: Arrow Author(s): N. Stephenson ISBN: 0099410672		Title: Database Systems Year: 2004 Publisher: Addison-Wesley Author(s): T. Connolly, C. Begg ISBN: 0321210255 Location: Harlow Edition: 4

 
 
 
 
 
 

Books are uniquely identified by their ISBN, authors by the combination of their last name and initials, and publishers by their name.
Deliverables:
There are two main components to the assignment – a design worksheet, and the database program itself. These are both worth 50% of the marks available for the assignment.

How and what you must submit:

Answers to your design worksheet needs to include screenshots from Question 5 onwards as proof of evidence of your designed database. Submit a Digital copy of this assessment and your designed database (export DB file) as per guidelines in e-Learning to submit your assessment via email. Printed hard copy of all pages including assessment coversheet pages submitted to your assessor.

 

 
 
The design worksheet should be provided as a written requirement for the functionality of your database, it consists of a series of exercises for you to work through. The questions start with database design and lead on to writing queries to perform various tasks – such as adding, removing, and searching for books.
You should work through the design worksheet first, as it may help to identify potential problems in your design before you get involved in the programming component.
In particular, if you cannot write the SQL queries required in the worksheet, then you may find it very difficult to do the programming component.
Once you have completed the design worksheet you should set up any tables and other database objects that you need before moving on to the programming component.
 
 
 
 
 
 
Once you have completed the design worksheet, you should go on to do the programming component.
In this part of the assignment you will write the SQL statements written in design worksheet and obtain screenshots of the results/outputs.
 
Screen shots are to be provided to all questions from Question 5 to Questions 9.
 
 

 
Design Worksheet
Provide written requirement report for the functionality of the database. Your report needs to include answers to all the below questions.
Question 1 (2 Marks): From the problem description in the assignment, identify the entities that need to be represented in the database, the attributes of each entity, the relationships between the entities, and the cardinality ratios of each relationship. Also include a data dictionary table

WRITE YOUR ANSWER HERE

 
 
 
 
 
 
Question 2 (2 Marks): Draw an Entity-Relationship Diagram illustrating the information you have identified in Question 1.
DRAW YOUR ENTITY-RELATIONSHIP DIAGRAM HERE

 
Question 3 (2 Marks): Describe the changes (if any) that need to be made to the Entity-Relationship Diagram you have given in Question 2 before it can be implemented as tables in SQL. Provide your final list of entities and their attributes, cardinality rations of each entity-relationalships. Also include your final data dictionary table.
