Practical Examples For Establishing Web Service Security In .NET
News Yet the majority of this information is conveyed as abstract theory, as opposed to practical, real-world implementation. You could, in theory, pass a user ID and password to every method in your Web service, but a more object-oriented approach is...

Exploring The Digital Universe
Leader Information theory is the newest of sciences: it will become one of the most important. Information theory says that by itself, information is meaningless — it has to be in context to be useful. Our physical universe is increasingly mirrored by our...
