In a web service there are huge business transaction occurs. Sometimes in business transaction, it needs to deal with faults that can arise in any stage of transaction. So always roll back mechanism is not possible to solve this problem. In order to achieve a common business goal, the protocol of interaction must be correct. In this project we have established a Broker system and encode this overall model into PROMELA (Model checking Language). For verify this model we also have used linear temporal logic and convert it to never claim property to verify this model accuracy. If any oversight happened then a compensation mechanism has been used to handle the situation.

When a user praised highly or badly about any product or service it created a butterfly effect of individual advertisement that reached far beyond the limit that the service/product provider could reach themselves . In classical period Books and newspapers have done this reviewing job and now this is again done by the individual user using various sites on the internet .By using this reputation new or undecided user of a particular product/service were able to choose properly We have tried to create an online service that helps to review a restaurant by an individual user which will not only able to create an online reputation for the users but also help the individual /a group of users to find a better choice of places for them.
