To view an employees projects click on the . The Add Project button inserts a new row into the WORKS_ON table after you enter the Project Number and Hours. Suppose that an EMPLOYEE can work at most a total of 40 hours on all projects they are assigned. Write a trigger called MaxTotalHours for the WORKS_ON table that will generate user defined error message if an attempt is made to assign the employee more than 40 hours. This trigger should be called before an insert to the WORKS_ON table so that the insert fails if the new hours increases the total over 40. The error message should give the number of hours entered, the number currently worked and a statement that it is over 40 hours. The web interface will display the message as shown below:

Jessie has received a contract to build a real-time application for a baker. however, the baker doesn't want to invest too much money. his only requirement is that he wants the customers to know which cupcakes are available at what time and in what quantity. so his core requirement is that the details of product should be in real time. what platform can jessie use to develop this application?
