Abstract

As the important of global data sharing is widely utilized in many corporations, it is well know as multidatabase. However, the system occurs and interesting issue. It is global constraint checking. It is mandatory to set up a potential checking application inside; therefore, global constraint checking needs these following essential characteristics such as 1) mobility 2) heterogeneity and 3) robustness. The effective way to implement the checking is using Aglets which is well recognized as one of the good mobile agent. Aglets is very appropriate because it contains the ability of mobility, and it is 100% Java compatible and open source. In this thesis, we construct the application of global constraint checking following these steps. To begin with starting step, user enters the insert statement. The system then receives the input, and then connection with Global Metadatabase begins. It will optimize the proper route for checking. Its optimized data will be sent out with the mobile agents to the remote sites. Eventually, results will be collected and show to user.
