Object-oriented and relational approaches in database management systems (dbmss): design, implementation and industrial markets
International Journal of Latest Trends in Engineering and Technology · 2017
Between 1960 and 1969, electronic files were used by most of the people to save their important data on any computer.Then and after few years, database technologies have replaced the file systems.Databases' design began as a simple art and has been converted by many developers to a methodology that basically makes database applications easier to use (Teorey ,1990).Consequently, Database Management Systems (DBMSs) is now one of the essential subjects in computer science.Teorey (1990) defines DBMS as a system that manages and controls all the data in a database.To build a strong database system, the designers should choose a powerful approach in order to design their database.It is an evident that Object Oriented approach is commonly preferred by the database programmers and designers due to its practical and useful concepts that find the solutions of the logical and technical problems caused by earlier approaches.Conversely, number of researchers state that Object Oriented approach has its individual issues in database designing and implementation. II. BACKGROUNDA. Object-Oriented Approach It is believed that database designers mostly prefer to use Object-Oriented approach while designing a database.Essentially, Object Oriented databases are identified by classes where the methods and the values are saved.General behaviors and properties are described by classes (Blaha&Premerlani, 1998).AlRashdi (2011) indicates that the values are the properties or the data associated with the class whereas the methods are described as pieces of code that apply functions or the behaviors within the class.On the other hand, the object is a concept that inherits the
