Students will not be assessed on work that the tutor has not seen them produce in class so that attendance is required as part of this assessment.

Students are required to submit the work that they have completed during the lab session. The details of the lab work and requirements are provided on the online learning system. Marking Information: The assessments will be marked out of 100 and will be weighted 40% of the total unit mark. Assessment 2: Applied Project-1 Due date: Week 7 Group/individual: Individual Word count / Time provided: 2500 words Weighting: 30% Unit Learning Outcomes: ULO-1, ULO-2, ULO-3 Assessment Details: Reline Engineering is an engineering firm with approximately 600 employees. A database is required to keep track of all employees, their skills, projects assigned, and departments worked in.

Every employee has a unique number assigned by the firm and is required to store his or her name and date of birth. If an employee is currently married to another employee of Reline Engineering., the date of marriage and who is married to whom must be stored; however, no record of marriage is required if an employee’s spouse is not also an employee. Each employee is given a job title (e.g., engineer, secretary, and so on). An employee does only one type of job at any given time, and we only need to retain information for an employee’s current job. There are 10 different departments, each with a unique name.

An employee can report to only 1 department. Each department has a phone number. To procure various kinds of equipment, each department deals with many vendors. A vendor typically supplies equipment to many departments. We are required to store the name and address of each vendor and the date of the last meeting between a department and a vendor.

Many employees can work on a project. An employee can work on many projects (Project A, Project B etc.), but he/she can only be assigned to at most one project in a given city. For each city, we are interested in its state and population. An employee can have many skills (preparing material requisitions, checking drawings, and so on), but she or he may use only a given set of skills on a particular project. (For example, an employee WILLIAMS may prepare requisitions for the Project D and prepare requisitions as well as check drawings for Project E.) Employees use each skill that they possess in at least one project. Each skill is assigned a number, and we must store a short description of each skill.

Projects are distinguished by project numbers, and we must store the estimated cost of each project. Your assignment consists of two parts. Part 1. Conceptual Model • Identify Entities • Identify entity supertypes and subtypes and their types, inheritance, and discriminators. • Describe relationships between entities and their cardinalities • Identify entity primary keys • Draw a Conceptual Model Entity-Relationship diagram Part 2.

Paper for above instructions

Introduction

This document outlines the design and implementation of a relational database system for Reline Engineering, an engineering firm with about 600 employees. The database aims to efficiently manage employee records, projects, skills, departments, and vendor relationships. It will include a conceptual model and a logical model, detailing entities, relationships, and data attributes.

Part 1: Conceptual Model

1.1 Identifying Entities

In the Reline Engineering context, we identified the following entities:
1. Employee
- Attributes: Employee ID (Primary Key), Name, Date of Birth, Job Title, Marital Status.
2. Department
- Attributes: Department ID (Primary Key), Department Name, Phone Number.
3. Project
- Attributes: Project ID (Primary Key), Project Name, Estimated Cost, City, State, Population.
4. Skill
- Attributes: Skill ID (Primary Key), Description.
5. Vendor
- Attributes: Vendor ID (Primary Key), Name, Address, Last Meeting Date.
6. Marriage
- Attributes: Marriage ID (Primary Key), Employee ID 1, Employee ID 2, Marriage Date.

1.2 Identifying Relationships and Cardinalities

The following relationships were established:
- Employee-Department
- Each employee works in one department.
- Cardinality: One-to-Many (One department has many employees).
- Employee-Project
- An employee can work on many projects, but only one project per city.
- Cardinality: Many-to-Many (Many employees can work on many projects).
- Employee-Skill
- An employee can possess multiple skills, and each skill may be used by many employees.
- Cardinality: Many-to-Many.
- Employee-Marriage
- An employee can be married to another employee.
- Cardinality: One-to-Many (one marriage record can involve two employees).
- Department-Vendor
- Each department can engage with many vendors.
- Cardinality: Many-to-Many (Many vendors work with many departments).

1.3 Identifying Primary Keys and Drawing ERD

Identifying primary keys ensures that each entity can be uniquely recognized:
- Employee: Employee ID
- Department: Department ID
- Project: Project ID
- Skill: Skill ID
- Vendor: Vendor ID
- Marriage: Marriage ID
The Conceptual Model Entity-Relationship (ER) diagram can be illustrated as follows (not visually drawn here due to text limitations but the structure can be outlined):
- Employee (Employee ID) ------<- Employee-Department (Department ID)
- Employee (Employee ID) --- School-Project (Project ID)
- Employee (Employee ID) <----> Skill (Skill ID)
- Employee (Employee ID) -------- (Marriage ID)
- Department (Department ID) <----> Vendor (Vendor ID)

1.4 Conceptual Model Analysis

This conceptual model reflects the organizational structure and employee dynamics within Reline Engineering. It captures how employees interact with various projects, their skill sets, the departments they belong to, vendor relationships, and possible inter-employee marriages.

Part 2: Logical Model

2.1 Describing Data Attributes and Types

The logical model defined the types of data that will be stored in each entity:
| Entity | Attributes | Data Type |
|---------------|------------------------------------------------------|-----------------------------------|
| Employee | Employee ID, Name, Date of Birth, Job Title | Integer, String, Date, String |
| Department | Department ID, Department Name, Phone Number | Integer, String, String |
| Project | Project ID, Project Name, Estimated Cost, City | Integer, String, Decimal, String |
| Skill | Skill ID, Description | Integer, String |
| Vendor | Vendor ID, Name, Address, Last Meeting Date | Integer, String, String, Date |
| Marriage | Marriage ID, Employee ID 1, Employee ID 2, Date | Integer, Integer, Integer, Date |

2.2 Redesigning to Remove Many-to-Many Relationships

To eliminate many-to-many relationships, we introduce junction tables:
- Employee_Project (Employee ID, Project ID)
- Employee_Skill (Employee ID, Skill ID)

2.3 Identifying Primary and Foreign Keys

Primary Keys:
Each entity's primary key remains the same.
Foreign Keys:
- In Employee_Project: Employee ID (FK), Project ID (FK).
- In Employee_Skill: Employee ID (FK), Skill ID (FK).

2.4 One-to-One Relationships

There is a one-to-one relationship for marriage:
- Each record in Marriage references two distinct Employee IDs.

2.5 Drawing a Logical Model Diagram

The logical model diagram can similarly be visualized as:
- Employee ----> Employee_Project <---- Project
- Employee ----> Employee_Skill <---- Skill
- Employee ----> Marriage
- Department ----> Vendor
This model effectively represents relationships among various entities, aligning with their real-world interactions.

Conclusion

The project revolutionizes Reline Engineering's data management by accurately defining the roles and relationships of employees, projects, skills, and external vendors. This structured methodology will not only aid in efficient data handling but also enhance reporting, ensure data integrity, and streamline operational processes.
