So far your business service has had a one-to-one relationship between an entity object and a view object. The CustomersView view object maps to the Customers entity object, and only that entity object. However, the reality is that when dealing with information about a customer, the end user really requires information pulled from a number of different sources. For example, CustomersView has an attribute AccountMgrId, which is the identifier for the account manager assigned to this customer. The problem here is that the value of AccountMgrId is something like 145 and so really doesn t mean anything to the end user. Instead, the application should show the name of the account manager looked up from the Employees table using AccountMgrId. ADF Business Components provides a feature that allows a view object to be based on more than one entity object and takes care of looking up the correct information from the various entity objects.

NOTe At this point JDeveloper may display a warning that the query has a custom where clause. This is to alert you that JDeveloper is about to alter the view object SQL statement and, if you have added a where clause, your custom edit may be overwritten. If this occurs, you should choose to overwrite your custom where clause. You can reapply it at a later point. At this point accept the defaults for the other values on this view object editor page. NOTe When you added Employees to the Selected list, you may have noticed that JDeveloper automatically picked up the association CustomerAccountManagerFkAssoc. This was the association created automatically based on the foreign key relationship between the tables Customers and Employees. The framework uses this association to ensure that you are looking up the correct employee information based on the AccountMgrId. The next step is to define which attributes from the Employees entity object you want to include in the CustomersView view object. From the view object editor, select the Attributes tab, select the down arrow icon that is part of the green plus button, and select Add Attribute from entity. Move FirstName and LastName from the Available list to the Selected list, noting that EmployeeId is automatically included as well since this is a key in this relationship. It s important not to remove this attribute because the framework uses both instances of EmployeeId for coordination.

You will probably notice that attributes referenced from the Employees entity object are read-only. This is probably what you require in most cases; however, you can set these attributes to be updatable when defining the lookup. TIp Look at the query for CustomersView to see how the view object is implementing this lookup. You may also want to add lookups in other view objects where it might make sense; for example, OrderItemsView to look up product name and product description from the ProductInformation entity object.
