 Case Study: Developing a database for Sports Goods sale businessSporting Goods Direct (SGD) is a directly selling catalogue based retailer of Sporting Equipment. Customers select the items and complete an order form, which is processed by SGD. Recently SGD has seen a considerable growth in the business with lot more sales than the first quarter of the year 2015.Demand for their stock have grown, therefore they need a well-designed relational database for stock maintenance and customer record purposes.Sporting Goods Direct sells many Items under many Categories:·         Men

• Women
• Children
• Footwear
• Clothes
• Accessories etc

The minimum details to be stored for each item are Item ID, Item Name, Category, Description, Price, Quantity, and Re-order Quantity.

The Customers need to register before being able to purchase an item. The information customers must provide are:

• First Name
• Last Name
• Date of Birth
• Email
• Contact Number
• Address

Many Suppliers can supply items sold in the store and one supplier can supply many items. Each item is supplied at a particular price. The store needs to record details of each supplier in the database. The respective details are: Supplier ID, Supplier Name, Address and Contact Number. All transactions between the store and the supplier need to be recorded.

Sporting Goods Direct needs to maintain and record all the Orders made with details like Item Ordered, Quantity Ordered, Order Date, and Total Amount. Their system later generates an order form, which contains Order Number, Item Code(s), and the Quantity Ordered.

Design a database for SGD indicating the necessary keys and relationships. Draw ER Diagram and map them to Relations ensuring that the database is in the third normal form.

You must design a database with the above mentioned specification indicating the necessary keys and relationships. Draw ERD diagram for the entities along with their attributes such that the database is in the third normal form (Apply 1NF, 2NF and 3NF).

Notice: Assignment must meet all requirements/learning outcomes specified in order to achieve Pass.

Task 1 (LO: 1.1, 1.2, 1.3, M1, D2) 1.1      Compare and contrast the integrated database environment with             the traditional file processing environment.  Analyse the different data model approaches to database design [Assessment Criteria: 1. 1, 1.3]

1.2      Illustrated with suitable examples from the given case study the meaning of data warehousing and data mining [Assessment Criteria: 1. 2]

Task 2 (LO: 2.1, 2.2, 2.3, M2, M3, D1 & D2) 2.1  Create a schema listing the attributes for each entity identified and show that your schema is normalised (at least in 3NF). Identify primary, foreign and composite keys if there are any. [Assessment Criteria: 2. 3] 

2.2  Draw an entity relation diagram that will enable you to create a database for online sport items sales. Resolve “many to many” relationships if there are any. State any necessary assumptions. [Assessment Criteria: 2. 3]

Hint : Example of ER

 2.3  Use query language (MySQL) to create the database with minimum six tables with necessary attributes and declare primary and foreign keys where necessary. Justify that the implementation meets the user requirements in the case study. [Assessment Criteria: 2. 1, 2.2]

Task 3 (LO: 3.1, 3.2, 3.3 M3, D2& D3)3.1 Insert at least 5 records into each table created. Also provide a screenshot of the records in each table. [Assessment Criteria: 3. 1]

            Hint: 

3.2 Using MySQL as visual tool, demonstrate the extraction of meaningful data through the use of “Select” statement. Provide screenshots with MySQL code for the following Queries. [Assessment Criteria: 3.2 & 3. 3]

           Hint:

 Query transactions

1. List all the available items in the store.
2. List all the customers’ name, address, phone and email.
3. List all the orders for a customer, for example: Jason James in ascending order by date.
4. List all the customer IDs, names, order-date, items’ ID and items’ name purchased in March 2016.
5. List the customer names whose purchase is more than £50
6. Count all the items sold in April 2016.
7. Display the total amount of items sold in May 2015.
8. Update the customer Jason James city from Luton to London.

Task 4 (LO: 4.1, 4.2, 4.3, M1, M3, D1, D2) 4.1  Evaluate each query above, providing the SQL statement and show the output from the query. [Assessment Criteria: 4.1] 4.2  Using MySQL, implement and test the verification and validation process with above 8 queries from the database illustrating the understanding of the various features of SQL (update, sorting, joining tables, conditions using the where clause, grouping, set functions, sub-queries etc.).  [Assessment Criteria:  4.2]

       Hint: Example

 4.3  4.3 Explain different database testing techniques. Apply one of these techniques to your own database implementation. [Assessment Criteria: 4.3]
