Scenario:

Customers, Product and Orders scenarioThe following data model is designed to hold information relating to Customers Ordering Products. For this scenario we need to define the following facts:These facts define the requirements which the Database must meet and should be agreed between the Database User and the Database Designer prior to physical creation.The draft facts have been defined as: The Entities required should include and additional entities you should add with related attributes and relationships.

Customers Orders OrderLines Products Suppliers

The Entities are related as follows: An Customer can have One or Many Orders An Order can contain One or Many Products (OrderLines) A Product can be associated with One or Many Orders A Supplier can supply One or Many Products

The design allows a Customer to place zero, one or many Orders. An Order can be for one or many Products, and this Product can be associated with zero, one or many Orders (the reason for the Link_OrderProduct table)

Note: Mention your valid assumptions clearly.

Tasks:

1. Design the database with the constraint that the available technology is relational. Your design should :1.1. Explain what is data model, Evaluate different data models explain why older data models are being

replaced by new data models(P.5.1)1.2. Analyse the case study and identify the advantages and disadvantages of having a database approach

for the company(P1.1,P1.2,P1.3)1.3. Briefly explain the concept of database management system and its importance using examples from

different database environment(P.5.3) (P1.1,P1.2,P1.3)1.4. Draw an entity relationship diagram with proper standards .Identify important keys, cardinalities and

represent different types of attributes and relationships. (P6.1) (P3.2)1.5. Draw Relational Schemas. Effectively map conceptual data models with relational database schema

according to the mapping algorithm. All the steps should be clearly mentioned (P6.2) (P3.2) (P2.1) 1.6. What is data normalization? Get normalized relational schema diagram. (P6.3) (P3.1) 1.7. Create the database using MS ACCESS. (P2.3)1.8. Create appropriate management queries (P2.2)

1.9. Create suitable reports and forms using Ms access. (P2.2) 1.10. Create the database using SQL server. (P7.1)1.11. Describe what database is testing and explain why it is important in your data base design. (P8.3)1.12. Explain the access rights to various type of users (P8.2)

1.13. Write sql queries for below questions.(P7.3)

1. Which Products have been Ordered by a Customer 2. What date/time was a particular Order dispatched 3. How many open Orders do we have in the system 4. What is the Total Order Cost for a certain Order 5. Which Supplier supplies a particular Product 6. How many of a certain Product do we have in stock 7. What is the mark-up on a certain Product

1.14. Verify the correctness of your triggers (P8.2) 1.15. Generate the suitable report of the company using graphical format (P7.2)1.16. Create a proper documentation to explain the way you create the database and document all the

above tasks. Documentation should include the printed screen shots to further clarify certain design decisions made, printed examples of reports. (P8.1) (P4.1,P4.2,P4.3)

2. Briefly explain data warehouse and data mining, then discuss what are the possibilities of apply above concepts into your database.(P5.2)
