What do you mean by showing booked in the other site? Do you mean it tells you the ticket was booked by the other site, or do you mean that both websites are updated so the ticket is unavailable on both?

If the latter: The ticket provider, a theatre, airline, railway company or whatever, maintains a database of tickets. Both booking sites have access to that database and can update it whenever a ticket is sold.

On a small scale, both may actually use the same DB, or -on a much larger scale- a Global Distribution System was used.

Hi Campbell thanks for the reply, Sorry if my question is nto proper. for example if i take redbus.in and cleartrip.com if i book a seat from redbus.in the same same bus will be some as booked in cleartrip.com, How is it possible thus both maintain a single database or any technology is used as Ulf Dittmer told about Global Distribution System

This is just a guess...but...

redbus has a database of their buses and seats. Cleartrip calls them up and says "we want to sell seats on your buses". ignoring the licensing and money aspects, redbus would say "Ok...here's how you connect to us".

They may have a webservice. Cleartrip would basically make a method call over the web saying "we want to know what's available on this day between a and b", and then "ok. we want to reserve a seat on this bus". redbus gets those messages, and sends back the relevant data for each.

It is also possible redbus could say "OK, you can log onto our database directly. Here is your login credentials".

So there is basically one "source of truth" as to what is available. The owner can then allow other people/applications/vendors to access it or not, depending on their specific business rules.

The supplier of the service can keep a single database. You cannot expect both redbus and cleartrip to maintain details of the tickets. The bus company do that. They update the database with different prices and routes as they become available, and provide access to it to redbus and cleartrip.

It could work that way, but it could also use a GDS, as I mentioned earlier. As a customer you generally won't know which one it is, and it really doesn't matter - the important thing is that the booking went through to whoever will fulfill it.
