    A relation schema can be thought of as the basic information describing
    a table or relation. This includes a set of column names, the data types associated
    with each column, and the name associated with the entire table. For example, a
    relation schema for the relation called Students could be expressed using the following
    representation:
    Students(sid: string, name: string, login: string, age: integer, gpa: real)
    There are five fields or columns, with names and types as shown above.
