Such scenario demands maximum mobility and rapid information retrieval that points to a mobile application. The paper presents an application developed for local and remote use, called InHand, that is context-aware, presenting information related to the current user context and provides location-aware support through the use of the Global Positioning System (GPS). The location system keeps track of a client ’s location, schedules client visits for a given day, help user navigate through a map using real-time position acquisition, and gather the pathway followed by a user on a given day. The application has two channels: server and mobile client. The mobile client can synchronize data with the server, and relies on a local database to minimize wireless traffic to a minimum. We use Remote Data Access and Web Services to access remote data in a convenient way. Although the application is designed with book selling in mind, the concept is perfectly extendable to other fields of application.
