Scheduling in Real time
I have been developing a session - like a webinar or a podcast for students to attend. It is driven by custom objects at present.
The problem I am facing is actually scheduling this in real time.
For eg: Assume that a Student opts a session for 4:30 tomorrow. They must get a notification before a day like today at 4:30.
Is there a way where we can schedule this based on the field of CO? or do we need an actual system which keeps watch of this and sends notifications accordingly?
I was thinking of web services. Is my idea wrong? Please suggest.
