In this tutorial, your task is to implement the SQL solutions for the given query below. The queries are based on the Company database that was used in the fecture. Build the Company DB by using the three SQL files available on the course web site on the appropriate week in the same way you built the DB in previous tutorials. The first file "BldCmpnyDB" which builds the relation DB schema and "PopltCmpnyDB" file populates the tables with data, and the last file, "SetLnkCmpnyDB" sets all the links between tables. The diagram below represent the logical data model for the Company DB and shows the links between tables. Primary keys are underlined. 3. For the following network diagram: a) Perform a Forward Pass and a Backward Pass b) Determine the critical path(s) C) Draw the Gantt Chart 1.

For each project on which more than two employees work, retrieve the project number, project name, and the number of employees who work on that project. 14. Give all employees in the 'Research' department a 10% raise in salary. 15. Make a list of all project numbers for projects that involve an employee whose last name is 'Smith' as a worker or as a manager of the department that controls the project. 16.
