Message Broadcast Framework for Local Storage in Distributed Applications

The applications dedicated to the spa and leisure are in huge demand due to the latter growth in developed countries. This type of applications has been designed to manage activities at hotels, health spas and leisure venues. Usually appointments are booked quickly and efficiently via a series of flexible grid control screens or through an availability search, where the system automatically finds available times. This paper presents a solution for the problem of “Concept Spa & Leisure” application. Nowadays it generates thousands of records daily, which leads to increase data on database. Currently, the application is facing a performance challenge due to the amount of data involved in the booking process. The objective of the present work is to propose a dedicated notification framework to optimize the Concept Spa & Leisure application. The main goal of this framework model is to reduce traffic on wire between client application and database server. This would be achieved by using as much as possible data stored locally, rather than requesting it from database every time it is needed. The search engine process is speedup by keeping as many data as possible within the client application. A message broadcast framework will be created to maintain local data synchronized with database. The main idea is to have a parallel system to keep watching data changes on database and as soon as data change, a message will be sent to processes to inform that current data held is out-of-date and must be refreshed before use in client application.
