12.5 SUMMARY
This chapter discussed pervasive data mining of databases from mobile devices through the use of Web services. By implementing mobile Web services we allow remote users to execute data mining tasks from a mobile phone or a PDA and receive on those devices the results of a data analysis task. A prototype based on a J2ME client has been discussed by describing the data selection task, the server invocation mechanisms, and the result presentation on a mobile device.
Although mobile data mining is not yet in a mature phase, it represents a very promising area for users and professionals who need to analyze data where users, resources and applications are mobile. On the basis of our experience, we can conclude that the combined use of a service-oriented approach with mobile programming technologies makes easier the implementation of mobile knowledge discovery applications that manage heterogeneous and pervasive scenarios where data and processing can migrate across different locations.
