THanks for asking John, i understand the business object concept, but a business object is a entity representation of domain, they're have rules not the table, in this case i need use 2 tables for implementation of 1 business object, but i dont idea how i can save data in both tables with one business object, the another chance is create 2 business object, but i try to make the first choice work for design purposes, i use Visual UML and the class is a modeling for the domain, and put a business object for each table break the uml abstraction, or i am wrong?, i really expect help , i can't write a line of code to have all clear in my head.

Best Regards

Francisco

>I think you may be a bit confused as to business objects and usage. For what you are describing, I think you are confusing a business object with a data services tier. A business object ensures that the business rules for the organization are followed -- although it probably does include some data writing, while a data services tier (one or more objects) might be spawned to manage the actual read/write/delete for raw data.

>>Hello, i have 2 tables, 1 table have the properties from a object, and second table have the information for working with users, like invoice_properties and invoice , i need create a business object for every table?, a business object for invoice_properties and another business object for invoice?, or i can put the 2 tables in one business object?, the invoice_properties only have the behavior and invoice all the data, but the table invoice save the data in way how is setting the invoice_properties, some one help me?, i try to make a 1 view for 2 tables but this is a problematic way for update information, then i need use 2 views, then i need 2 business objects too?.
