Learning Outcomes The Subject Learning Outcomes demonstrated by successful completion of the task below include:
a) Examine the role of data in an organisation, and develop solutions related to the creation, storage and management of organisational data. Data plays a critical role in organizations, as it is used to inform decision-making, support business operations, and measure performance. Some specific ways that data is used in organizations include:

Decision-making: Data is used to inform business decisions by providing insight into trends, patterns, and relationships. This can help organizations make more informed and data-driven decisions.

Business operations: Data is used to support a wide range of business operations, such as sales, marketing, finance, and human resources. For example, data can be used to track customer interactions, forecast demand, optimize production processes, and measure employee performance.

Performance measurement: Data is used to measure organizational performance in various areas, such as financial performance, customer satisfaction, and employee engagement. This can help organizations understand how they are performing and identify areas for improvement.

To ensure that data is effectively used in an organization, it is important to have solutions in place related to the creation, storage, and management of organizational data. Some specific solutions that organizations can consider include:

Data governance: Establishing policies and processes to ensure that data is collected, stored, and used in an ethical and compliant manner.

Data quality management: Implementing processes to ensure that data is accurate, complete, and consistent.

Data security: Protecting data from unauthorized access or misuse through the use of measures such as encryption, access controls, and backup and recovery procedures.

Data storage and management: Implementing systems and tools to store and manage data in a way that is efficient and scalable. This can include the use of databases, data warehouses, and cloud storage solutions.

Data analytics: Using tools and techniques to analyze data and extract insights that can inform decision-making and support business operations.
b) Design solutions applying relational database techniques to complex problems and communicate these solutions to all stakeholders.
c) Apply contemporary database modelling to identify and address anomalies in data and recommend solutions.

Task Summary
This final assessment requires you to produce a robust and a flexible database that is able to accurately store information about the business mentioned in the case study. You also need to develop the queries and reports to provide data insights which in turn drive business decisions. Your submission should include:
a) Appropriate modelling plus any business rules or assumptions
b) SQL commands to
• physically implement your logical model
• populate the database
• retrieve meaningful information
c) Visualizations that can be presented at a board meeting
Context
This assignment brings together all the learning gained over the duration of this subject. The skills and knowledge you’ve gained in this subject forms a vital part of your ability to traverse the major disciplines in the data and database fields. You will be able to interact with analysts, developers, database administrators and managers using a common language which is vital if an organization is to function effectively. These skills are the groundwork for further career progression in data analysis and information management.
Task Instructions
1. Group Formation and Registration
• Form groups of 3 members.
• The deadline for team registration is 11:45pm AEST Friday end of Module 2.2
• To register your team, you are required to send your Learning Facilitator an email with “[MIS602] Group Registration” in the subject line. In the body of that email, please list the names and student ID numbers of all the members of your team.
• You are required to send the registration email to your facilitator before the registration deadline.
• After the registration deadline, those students who are not in a team will be allocated to a group by the Learning Facilitator.
2. Case Study
Please read the attached MIS602_Assessment 3_Case Study.
3. Database Case Study Report
Based on the information provided in the case study, create a functioning database using MySQL that can be queried to meet the requirements of the business.
4. The database case study report should include the following elements:
a) ER diagram, relational model and associated business rules and assumptions b) SQL commands to:
• Create tables and Insert sample data rows into each table
• SQL queries to provide business insights At least one of each of the following is required:
• SELECT Question Assignment with a condition
• GROUP BY Question Assignment
• JOIN Question Assignment o NESTED Question Assignment
For each Question Assignment explain its business value i.e. what business question does the result answer? Does it save money/more efficient process?
c) At least two visualizations with an explanation of its business value.
For each visualization explain its business value. E.g. does the visualization highlight savings in time or money?
