A number of the projects we have worked on have involved adding a database to existing systems to provide billing platforms. This has involved creating interfaces to collect CDRs (Call Data Records), store and rate them then provide a web interface to provide bills and reports.
We have also provided complete systems that allow text and multimedia messages to be sent and received from mobile phones. This project required not only the development of the web site, but also interfaces to several vendor's APIs for message transfer and ongoing support for multiple resilient servers.
Finally there have been a number of projects that use databases to allow our customer to keep the data on their website up to date with news, special offers or stock levels.
