Task Summary
In this assessment, you are required to demonstrate your ability to understand the requirements for various data information requests from an existing database and develop appropriate SQL statements to satisfy those requirements.
Context
Being able to query a database is a fundamental skill that is required by all information systems professionals who work with relational databases. In this assessment, you will utilize the basic query skills that are typically used to extract information for analysis, reporting and data cleansing in a data management setting. Timely provisioning of key business information promotes effective communication and enhanced solution delivery.
Task Instructions
Please read and examine carefully the attached MIS602_Assessment 2_Data Implementation_ Case study and then derive the SQL queries to return the required information. Your focus should be providing the output as meaningful and presentable possible. Please note, extra marks will be awarded for presentation and readability of SQL queries including ordering of the columns
Please note all the SQL queries should be generated using MySQL server either using MySQL workbench or MySQL Command Line Client.
Provide SQL statements and the query output for the following:
