| Abstract | ||
| This research implements the concept of Object Relational Data Base Management System (ORDBMS) on depreciation by converting it from relational application to object application without changing current relational application and dealing with its details by using Object Views. Object Views can be derived from the relational system and form a layer of object oriented program above the relational table. Thus ,it gives us new method for making queries on relational database and decreasing SQL sentences by using MAKE_REF instead of making complex relations between multiple tables so data is viewed as one unit. by using CAST_MULTISET multiple data can be implemented into object view without making multiple relational between collections. The application is programmed using Oracle8 because it has the propriety of object relational data base and also it provides INSTEAD OF trigger for inserting and manipulating data in the relational table by using object views. | ||
