Student/Course/Timetable records

Implemented RESTful api for GET/POST/PUT/DELETE 4 web services, the passing data format is JSON or parameters.

GET feature lets the user can search for a student who is taking what courses and its information by student Id, or a course is taking by whom by course id, or search for all students/courses/timetables' records.

POST feature allows the user to add student/course/timetable records.

DELETE feature allows the user to delete single row of records or wipe out all records.

PUT feature allows the user to update records by thier relevant Id.
