More on Sigma

I finally spoke to Kevin Spark at Sigma regarding their technology. They are making good use of “Windows Communication Foundation,” which is now .NET 3.0. They are using a lightweight transaction manager that can cache data locally and be notified when it gets updated on a database. This reduces roundtrips to the database (for things like authenticating username and password that get lots of use with very few data changes).

They are also using some homegrown tech innovations that I am precluded from talking about, or even describing. Suffice to say that when they are ready to introduce their new browser-based system later this year, it will be well worth waiting to take a good close look at.
