Pretty good ADO replacement I feel i have to thank its authors.
Easy to use, very fast -- much faster than common tools, nice XML and datatype conversion features, low memory usage.
We use it with two servers - SQL Server for easy operations, and Oracle 8i for heavy queries. One component, same code.
They say they're going to release EJB and CORBA versions soon. So we'll be able to use it on unix platforms too.
Very recommended.
