Extreme Transaction Processing Patterns: Write-behind Caching

MicroORM - A Dynamically Typed ORM for VB and C# in about 160 Lines
Using the new DLR features in VB 10 and C# 4 you can build a configuration-free ORM that works well with legacy stored procedures. Though accessed using normal object-dot-property syntax, all the data objects are built at runtime based solely on the information returned by the database. And this is done with no interfaces to define, classes to implement, or data mapping definitions to write.

Schema for Web Services – Part I: Basic Datatypes
Most web service developers rely on a data binding conversion layer within a web service to work directly with data structures in their programming language of choice - but this causes a number of problems. In the first of a series of articles that look at these problems, Dennis Sosnoski starts at the most basic level, looking at simple data types and the issues that arise from mapping them.
