<u>Software modelling:</u>
Software modelling can be defined as the ways of expressing the design of the software.
Software modelling tools have great significance in developing and representing the design of the software.
The software modelling tools can be used to estimate the work needed to done per task by determining the work to be done on each task that constitutes the build of the software and then the individual amount of work done per task can be added for all the tasks and the total amount of work to be done is obtained as a result.
Answer:
SELECT last_name, job_title, hire_date FROM employee WHERE hire_date>="01-12-2016" AND job_title != "STOCK CLERK" ORDER BY job_title DESC;
Explanation:
The SQL code queries the employee table returning records of the last_name, job_title, and hire_date columns matching the employees hired on or after December 2016 and job titles that are not stock clerks in the employee table.
The WHERE and AND clause is responsible for the condition while the ORDER BY clause returns the query result in the of the job title in descending order.
