Abacus Systems's Relational XQuery is an XQJ-compatible XQuery processor that allows you to execute XQuery against both relational data and native XML data sources. Relational data can be directly transformed to XML and aggregated and joined with XML data. Relational XQuery can be used in any application where relational data and XML must be integrated, such as Web Services applications, Service Oriented Architectures, and XML-based J2EE applications.
GPS Tracker allows someone to track a GPS enabled cell phone using Google Maps. The project was tested with a Motorola i355 cell phone on the Sprint/Nextel network. You need to have a data plan with the cell phone provider so that you can make updates to your Web site from the cell phone. There are two projects available. The first project is built with PHP and MySQL. The second project is built with .NET and Microsoft SQL Server. Both projects use Java (J2ME) on the cell phone.
Watchee supports GPS location based live tracking from mobile phones which support J2ME and PDAs running Windows mobile. The track can be viewed on a Web portal. Key features are high data compression to minimize your phone provider costs, chatting, fine grained buddy permissions, sending in real time, and location bound photos.
