Assume that you have a table named students in your database, with fields: redid, name, gpa, department, level. Write code to create a view consisting of redid, name and level, where changes to the view do not change the table. Assume you want to create an alias studs for students. Write code to achieve this alias, so you can refer to the table using either name. Explain why you might want to create an "index" on the field called name, for the students table
