By now you should have an understanding of how relational databases work and how to use SQL to create and manipulate data. Now it’s time to put that knowledge into practice. For your semester project, you are going to create a database that you might find at a college. You will be building this database from the ground up so you have many decisions to make such as naming conventions, how to organize data, and what data types to use.

Deliverables:

Document “Relationship report” showing
Table names used in the database
Table relationships
Keys
Table Fields names
Field Data types
Constraints
SQL (code) to create the following
Faculty contact list
Course Book List by Semester
Course Schedule by semester
Student Grade Report by semester
Faculty Semester grade report (number of A's, B's, C's, D's, F's per course)
Student GPA report by semester and overall (semester and cumulative)
Mailing list for Diplomas
Student Demographics over time (how many were under 18 last year, this year)

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
