Codd. • It is relational model in which data is stored in multiple tables where tables are related to each other using primary keys and foreign keys and indexes. For now, let’s focus on the main general advantages and disadvantages of each database type. Object-Relational Database Systems(ORDBMSs) can successfully deal with very large data volumes with great complexity. Developers appreciate their clear organization, normalization, and clear requirements to entered data. What is ER Model Advantages and Disadvantages of E R Model. The following figure shows the difference between relation and object-oriented database model. Advantages • Object database can handle different types of data while relational data base handles a single data. Pc Technical Pro - Free Computer Education A blog about computer education, networking, DBMS, programming languages and web design.

At present the vendors of all the major DBMS products have supported object-relational database management systems, but still its industrial adoption rate is relatively low. 2. Relational Database vs Object Oriented Database. Oracle Database implements the object-type model as an extension of the relational model, while continuing to support standard relational database functionality, such as queries, fast commits, backup and recovery, scalable connectivity, row-level locking, read consistency, and more. When working with object-oriented programming languages , like Java for example, an object database is advantageous.
