1-Consider using an XML document to represent information about students on an MSc programme. All information should be represented using elements rather than attributes. The root element of the document is programme. A programme has a degree, whose value in this case is "MSc", and a year, whose value in this case is "2018/19". These elements are followed by the results for the programme. The results are partitioned into distinction, merit, pass and fail. Within each is a sequence of name elements, each containing the name of a person having achieved the corresponding result for the programme. The actual results are as follows: Jemima Puddle-Duck and Peter Rabbit obtained distinctions, Tom Kitten obtained a merit, and Samuel Whiskers failed (nobody obtained only a pass).

2-Consider a relational database containing a relation teaches with attributes course and lecturer, representing the relationship between courses taught on an MSc programme and the lecturers who teach them. Give an XML document which represents a relation instance containing two tuples. (You are free to make up your own course and lecturer names.)

3-Now represent the information in both the above exercises in JSON rather than XML.

Do the exercises above An example of this is the questions that the professor solved in the pictures below
