I would use reference fields. <URL:http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Field-types> Something like db.define_table('customer', Field('name', 'text'), Field('address', 'text'), Field('city', 'text'), Field('etcetera', 'decimal(1,5)')) db.define_table('invoice', Field('reference', 'customer'), Field('opendate', 'date'), Field('shipdate', 'date'), Field('discount', 'decimal(2,5')) db.define_table('line_item', Field('reference', 'invoice'), Field('reference', 'catalog_item'), Field('quantity', 'integer'), Field('qty_shipped', integer), Field('backorder', 'boolean')) I've left off item charges and total due, but those would be simple to do as either a computed value, or a normal field not shown as an input but updated by an onvalidation method. Good luck!
