The quiz will be open after week 7 Part B: (60 marks) 1. SmartProjects Company is planning to design a data model to hold information relating to their projects, employees working on company projects and their customers. SmartProjects IT Manager provided following business rules to the software developer: Complete the information-level design for the database that satisfies the above constraints and user view requirements. In order to complete this information-level design you are required to answer questions given below 1(a) – (e) User view 1 requirement: Each employee has a unique ID number, and their first name, last name, date of birth, address, contactNo user name and password must be recorded. There is a need to keep track of the dependents of each employee for insurance purposes. User view 2 requirements: Each customer has a unique Cust_number and their first name, last name, address, PNum, project tile and Payment must be recorded. User view 3 requirements: Each project has a project number that uniquely identifies the project (PNum) and project title, StartDate, managerID, managerName,managerContactNo must be recorded. User view 4 requirements: An employee can work on only one project. A project can have one or more employees associated with it. User view 5 requirements: Each department has a unique ID number and name. A Department can have many employees. An employee can only work in one department. A department controls number of projects. User view 6 requirements: One project may belong to several departments. One customer can submit only one project at one time. a. Analyse the all user requirements given above, identify and list all entities described in each user requirement. (5 Marks) b. Add attributes to these entities and represent these entities (or Tables) and attributes as a collection of Tables and attributes. You are required to arrange them as given in the example below. NB: Select suitable primary key for each table and underline them. Eg. Customer (CustomerID, name,……. (5 Marks) c. Outline all relationships between entities. Eg. One project may belong to several departments – One-to-many, (5 Marks) d. Determine the functional dependences. Eg. CustomerID  name, address, …… (10 Marks) e. Then normalise these tables. Make the normalization to 3NF. State for every step in the normalization, which functional dependency that causes it. (10 Marks) 2. Represent the structure of your database visually by using the entity-relationship (E-R) diagram. If you make any assumptions about data that doesn’t show from the problem, they must be described. You can use Visio or any other software tool to create the ER diagram. (15 Marks) 3. Build this model using MS SQL Server by creating these tables and Relationships. Populate these tables with appropriate data, at least 3 records in each table. (10 Marks)   Marking criteria: Example of marking criteria is shown in the following table. Marks are allocated as follows: Section to be included in the report Description of the section Marks 1. a. identify all entities Identify entities all user requirements 5 b. User Views as Tables Represent the User Views as a collection of Tables 5 c. Relationships Determine the relationships between entities 5 d. Functional dependences. Determine Functional dependences. 10 e. Normalise tables Analyse above tables and normalise 10 2. ER Diagram Represent the structure of your database visually by using the ER diagram. Evaluate your proposed solutions 15 3.Model building Model building on MS SQL Server 10 Total marks or the Report 60 Assignment 1 Quiz marks Marks for Assignment 1 Quiz 30 TOTAL 90 Example Marking Rubric for Assignment 2 Report: Total Marks 60 for the report Grade Mark HD 100% DISTINCTION 80% CREDIT 60% PASS 40% Fail 0-40% User Views as Tables Ability to think critically and analysed clearly Relevant and soundly analysed.
