I am doing some research on object/relational mapping patterns for get object data persisted into a relational DBMS. I am hoping to just get a broader understanding of different ways to do things mostly. I found a fairly in-depth site that has some good concepts to build on (http://www.objectarchitects.de/Objec...erns/index.htm) but I am looking for more. Have any of y'all dealt much with this concept? What are your thoughts? and do you have any good resources?
