Task003

[antferman3]

• Workers can apply for jobs. The system must store the following data regarding the applications: a reference number, a creation moment, a status, a statement, some skills, and some qualifications. The reference number is a unique string with a minimum of five characters and a maximum of 15 characters; it’s strongly recommended, but not required, that application references should match the following pattern: “EEEE-JJJJ:WWWW”, where “EEEE” and “JJJJ” have the same meaning as before, and “WWWW” is a four-letter string that helps recognise the worker. An application status can be either “pending” if no decision has been made, yet, “accepted” if the decision was to accept it, or “rejected” if the decision was to reject it.
