Description

Students Enroller (Database Tables Version) is a C++ program that allows the user to select, insert, print, and join students and grades tables information using the Finite Set (represented as database tables) and Linked List (represents rows in a table) data structures. This program is made-from-scratch and does not utilize the C++ Standard Template Library (STL).

Compilation and Execution

• Compile: g++ *.cpp
• Run Program: ./a.out

Program Commands

• insert students <student-id> <first-name> <last-name>: Inserts a new student into the Finite Set (represented as a students table in a database).
  • Examples:

      tables> insert students 5 Mickey Mouse
      tables> insert students 2 Papa Smurf
      

• insert grades <student-id> <term> <year> <grade>: Inserts a new grade into the Finite Set (represented as a grades table in a database).
  • Examples:

      tables> insert grades 1 Spring 2016 B
      tables> insert grades 2 Summer 1738 A
      

• select <table-name> <attribute-name> <value>: Selects a set of user-defined values from a table and prints out the resulting rows returned.
  • Examples:

      tables> select students id 2
      (2,Papa,Smurf)
      tables> select grades term Summer
      (2,Summer,1738,A)
      

• print: Prints out all of the rows of a table from the Finite Set in tuple notation.
  • Notes:
    • students table format: (id,firstname,lastname)
    • grades table format: (id,term,year,grade)
  • Examples:

      tables> print students
      (5,Mickey,Mouse)(2,Papa,Smurf)
      tables> print grades
      (1,Spring,2016,B)(2,Summer,1738,A)
      

• join: Joins the students and grades tables based on the following attribute order: (id,firstname,lastname,term,year,grade).
  • Example:

      tables> join
      (2,Papa,Smurf,Summer,1738,A)
      

• quit: Exits the program.
