The management of major-related data is something your department is interested in. Create a data structure that will keep your department's important information current. Of course, the majors list needs to be arranged by last name (and then by first, if there are multiple students with the same last name).
Develop a simple data model for a student database that includes student data, student contact data, student demographic data, student grades data, and student financial data.  Determine the data attributes that should be present in each table, and identify the primary key for each table.  Develop a complete entity relationship diagram that shows how these tables are related to one another.
The many-to-many relationship between entities is not supported by which data model? Please explain the model's advantages and disadvantages.
