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.
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.
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:

15 List the details of the staff who served the highest number of customers. 5 Marks
16 Evaluate the ‘calledNumber’ column in calls, and write a query to find how many of these 5 Marks numbers are registered in this database (mobile network).
17 List all the active phone numbers that has never made a call. Show this query using: 5 Marks a) Nested Query
b) SQL Join
18 i. Create a view showing the popularity of all towers based on number of connections 5 Marks made
ii. Use this view to generate the most popular tower location
19 Write a query to fetch the data about the first call. Include the phone number, towerID and the 5 Marks customer details (customerID and name) on which the number was registered. Note: you may get multiple records.
20 How long has the oldest and youngest active female staff worked in the company? 5 Marks
21 In not more than 200 words, comment on whether the tables are in 3NF. Justify your argument 6 Marks with relevant examples, and then explain at least two ways to improve this database based on what you have learned in weeks 1-8. Draw specific examples from the database to support your argument.
Total 90 Marks
1. The database used for this assignment is available in ‘MIS602_Assessment 2_Database SQL Files’ folder. You need to download and import the file into MySQL Workbench.
2. Copy and paste all the SQL questions into a word document. Under each question provide the corresponding SQL query, the first 10 lines of the result and the output as evidence of running the query. Submit the word document via the Assessment link in the main navigation menu.
It is essential that you use appropriate APA style for citing and referencing research. Please see more information on referencing here http://library.laureate.net.au/research_skills/referencing
