A P2P (Peer-to-peer) based General Practitioner software using VB.Net and SQL Server 2000.

The idea is to introduce the use of a Peer-to-peer architecture instead of a client server architecture, the reasons are:

1. Most of the doctors do not want to share the confidential patients’ data with other doctors.In case of the client-server architecture, the data is stored in the same database server (e.g. SQL Server 2000) and all the clients have access to the same database.

2. This could be a problem when they need to refer their patients to other doctors, because they often need to send their patients’ data to the referred doctors.

3. I introduced the use of P2P (Peer-to-peer) architecture to solve this problem. In this architecture each doctor installs a standalone database server (e.g. SQL Server 2000) and uses it privately. And they use P2P technology to exchange the data (in an XML format) with other peer doctors.

4. Web service technology is also used here for registration purpose that is to register each doctor to the Hub (the registration server which maintains all the P2P users).
