Database Tables
/////////////////////////
Before running application, we need to create a database and tables for individual server.
This project sports 4 servers named : a,b,c,d
For each server x in a,b,c,d, create

Database Name : Question_Bank_x
Tables : 
    1) question_details // that contains MCQ questions, its option, correct option, its weight, access_code

        create table question_details (
            id int unsigned auto_increment not null,
            question varchar(1000) not null,
            opt_a varchar(1000) not null,
            opt_b varchar(1000) not null,
            opt_c varchar(1000) not null,
            opt_d varchar(1000) not null,
            correct_opt varchar(1) not null,
            weight int not null,
            access_code varchar(32) not null,
            primary key (id)
            );

    2) access_code_rules // that contains rules associated with an access access_code

            create table access_code_rules(
            access_code varchar(7) not null,
            easy int not null,
            medium int not null,
            hard int not null,
            primary key (access_code)
            );

    3) access_code_rules_to_{z} // where z is a sever other than x, create table for each z

            create table access_code_rules_to_{z}(
            access_code varchar(7) not null,
            easy int not null,
            medium int not null,
            hard int not null,
            primary key (access_code)
            );

    4) failed_distribution_to_{z} // where z is a sever other than x, create table for each z

            create table failed_distribution_to_{z} (
            question varchar(1000) not null,
            opt_a varchar(1000) not null,
            opt_b varchar(1000) not null,
            opt_c varchar(1000) not null,
            opt_d varchar(1000) not null,
            correct_opt varchar(1) not null,
            weight int not null,
            access_code varchar(32) not null
            );

Runnning the application
////////////////////////////

Step 1: Open Intellij. Click on File. Click on Open and locate and select "quiz" folder.
        Navigate down to "server a/my_app". Open  my_app package. Similarly open "server b/my_app",

Step 2: Set jdk and mariadb_connector in classpath of each package.
Step 3: Select "import changes" in the pop up at lower right corner of window. 
        This fetches dependencies of the project mentioned in "pom.xml"
Step 4: Set Language Level 8 in Project Module.
Step 5: On Mac, Press control+shift+R on individual intellij window run individual package/server. 
        Alternatively, Click on "run" tab, then click on "run app" to run the app.

Step 6: Replace the nginx configuration file with the provided one at "quiz/nginx.conf".
Step 7: Start nginx. On Mac by writing the undermentioned command in terminal:
