ObjectView

In the Oracle object-relational database, an object view let you retrieve, update, insert,
and delete relational data as if it was stored as an object type. You can also define
views with columns that are object datatypes, such as objects, REFs, and collections
(nested tables and VARRAYs).

物件檢視
1. 在 Oracle 的物件-關係型資料庫中,利用物件檢視就可以像操作物件型別一樣對關係型資料進行DML操作
2. 使用者定義的檢視中也可以包含物件資料型別的列,常用的物件資料型別有物件 , REFs等
