CONCLUSION
In the thesis the Object-oriented database technology is discussed as a symbiosis of object-oriented modeling and database technologies. The object-oriented data modeling provides the technique to encapsulate the attributes and the methods for processing the attributes.
It is shown how database storage mechanism incorporates object-oriented data and establishes the Object-Oriented Database Systems. Object-Oriented Database Systems are based on Object-Oriented Programming Language and Database storage mechanisms that depend on the data model established.
The Relational Database System (RDBS) as most popular one is discussed but with disadvantage not to use an object data modeling. The implementation of the object data modeling to RDBS significantly improves and simplifies the database design. This combination is named as Object Relational Database System
(ORDBS) and allows a designer to use convenient structured query language (SQL) with object features.
The thesis analyzes declared the features of Object Structured Query Language (OSQL) that includes Object Data Definition Language and Object Query
Language. This analysis with discussion of the advantages of OSQL was made by structuring the problem with object data modeling in Trading Company Database Design. The comparisons of the SQL statements made with and without object features showed that the implementing object data modeling approach in database design gives the following advantages:
simplify the design by reduction of the steps of abstractions for mapping the real life problem to the database structure design;
simplify the structuring of problem by using object data modeling
reduce the number of SQL statements in query descriptions;
speed up the query processing;
