Task002

[antferman3]

• Employers can publish jobs, for which the system must store the following data: a reference number, a status, a title, a deadline, a salary, an optional link to additional information, and a descriptor. The descriptor includes the description of the job and its mandatory duties; for every duty, the system must store a title, a description, and a percentage that indicates the approximate amount of time that each duty is going to take every week. The reference number is a unique string with a minimum of five characters and a maximum of ten characters; it’s strongly recommended, but not required, that job references should match the following pattern: “EEEE-JJJJ”, where “EEEE” is a four-letter string that helps recognise the employer and “JJJJ” is a four-letter string that helps recognise the job. The status can be either “draft”, if the job is not ready to be seen by other people, or “published”, if it is ready to be shown publicly. A job is said to be active if it was published and its deadline line has not elapsed.
