Object Oriented Database Model

What object-orientation actually? 

• The main idea in design is to maintain separate sets of memories that mean separate memory spaces for each and every individual row instead of collectively storing as all the rows in a single space 
• As a result data independence is achieved so that all operations and transactions done in one data are independent and unaffected with other data today’s minimum as possible .

Examples 

Some OODBMSs are designed to collborate with other programming languages (such as Java, Python, Perl, Delphi, Ruby, C#, Visual Basic .NET, C++, etc). Others have their own language of choice 

• • Versant Object Database by Actian
  • Objectivity/DB by Objectivity
  • ObjectStore by Ignite Technologies
  • Caché by Intersystems
  • ZODB by Zope

Advantages of OO design  

• Data Hiding: Giving access to only required data at different levels of users
•  Inheritance: data reusability 
• Data security and integrity: Providing different levels of access to different levels of users using access modifiers, validations, authentication
• Polymorphism: Using the same object in different ways
• Encapsulation: Combining different data from different units into a consolidated one 

Some DBMS are a hybrid of OODBMS and RDBMS, and are therefore referred to as object-relational databases (ORD)

You don’t need to know much more than this about this model. This is far too advanced and only used in top companies and is a piece of proprietary information.
