Welcome to our new blog post where we will guide you through the process of building a conference event registration and attendance tracking system using SQL (Structured Query Language).
Creating the Databases
The first step in creating this system is the creation of the necessary databases. We will need a database for the conference event and another for the attendees.
|
1 2 3 4 |
CREATE DATABASE ConferenceDB; CREATE DATABASE AttendeesDB; |
Now we have two databases, ‘ConferenceDB’ for the conference events and ‘AttendeesDB’ for the attendees.
Creating the Tables
Next, we need to create tables in each database to store detailed information about the conference events and attendees.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
USE ConferenceDB; CREATE TABLE Events( EventID INT NOT NULL PRIMARY KEY, EventName VARCHAR(100) NOT NULL, EventDate DATE NOT NULL, RegisterLimit INT NOT NULL ); USE AttendeesDB; CREATE TABLE Attendees( AttendeeID INT NOT NULL PRIMARY KEY, AttendeeName VARCHAR(100) NOT NULL, EventID INT FOREIGN KEY REFERENCES Events(EventID), AttendanceStatus VARCHAR(50) NOT NULL ); |
In the conference Event table, we defined the event ID, event name, event date, and register limit. In the Attendee table, we keep track of the attendee ID, name, and the event they registered for including their attendance status.
Tracking Attendance
Once we have everything set up, we can begin tracking attendance. When an attendee checks into an event, we can update our attendee table.
|
1 2 3 4 5 |
UPDATE Attendees SET AttendanceStatus = 'Present' WHERE AttendeeID = @AttendeeID; |
This SQL command allows us to mark an attendee as present when they check-in.
Conclusion
This is a basic example of how to use SQL for an event registration and attendance tracking system. There is so much more you could do with SQL programming. You can add more functionality to this system like ticketing, payment processing, space allocation, and much more. The Structural Query Language, SQL, is a powerful tool that is pivotal in managing and organizing data.
Note:
All SQL commands should be executed using an SQL client like MySQL Workbench or SQL Server Management Studio against an SQL server instance.
