Web Services: Application Development Interoperability Mobility and Security Issues

Abstract

Web Services create a platform for applications to communicate with each other across different platforms. Web services enable machine to machine interaction, this finds great relevance in today s business world where processes can be automated hence minimizing human intervention. newlineWEKA is a very powerful desktop data mining application. A step by step procedure has been developed to convert the popular data mining application to a web service. Tests are conducted where it is proved that there is no loss of accuracy when the application is converted to a web service with the added benefit of being accessible to a number of users. Users need not install the application on their system instead they can utilize the data mining facilities by invoking the service through the internet. newlineIn today s world people would want to consume web services using their mobile device because of the anytime anywhere connectivity of mobile devices. In this thesis an attempt has been made to create a mobile enabled web service such that only registered users can consume the available web services and get benefited. It creates a level of abstraction for a person using this application in which he need not know how to programmatically invoke the web service. He only has to register online to the application and fill up a form which allows him to connect to the database and perform his search. Mobilink uses MySQL for the database which records and stores customer details. Form validation is done via PHP and entries like the date field where the number of days in a month are dependent on the month as well as the year (in case of a leap year) are filled in using JavaScript. Checking the username availability is done using AJAX. The web service as well as the mobile client is developed using Netbeans IDE. newline6 newlineInteroperability is the keyword of web services, but in spite of a large amount of research done in this field it is seen that some issues remain unresolved when web services and clients across different platforms interact.
