I'm trying to design some classes in Zope based on a SQL scheme. [Table] Product ProductID: Integer Description: String [Table]: Attributes AttributeID: Integer Description: String [Table]: AttributeValues ProductID: Integer AttributeID: Integer Value: String Which should produce a layout like: Product1 Product2 Product3 Product X Attribute1 Value Value Value Value Attribute2 Value Value Value Value Attribute3 Value Value Value Value AttributeX Value Value Value Value How do I implement this as Zope Classes. The data is mostly static, and theres only a few changes to the attributes over time. Regards
