Difference between DB2 and Oracle

There are many database systems available on the market today. Two of the most popular are DB2 and Oracle. Both have their pros and cons, but which one is best for your business? In this blog post, we’ll compare and contrast DB2 and Oracle to help you decide which one is right for you.

What is DB2?

DB2 is a powerful database management system that has become a standard in many industries. Designed and developed by IBM, DB2 allows users to store and manage massive amounts of data efficiently and effectively. DB2 offers a variety of advanced features that allow users to customize their databases to suit their unique needs, including the ability to manipulate large batches of data with ease and develop detailed queries for in-depth analysis. Additionally, DB2 is highly scalable, so businesses can rely on it as they grow and expand over time. Overall, DB2 is an invaluable tool for managing large amounts of data and driving business success.

What is Oracle?

Oracle is a software company that specializes in database management systems. Oracle’s flagship product is the Oracle Database, which is a relational database management system. Oracle also offers a wide range of other products, including application development tools, enterprise resource planning software, and customer relationship management software. Oracle has a long history in the software industry, and its products are used by many large organizations worldwide. Oracle is a publicly-traded company, and its shares are listed on the Nasdaq stock exchange.

Difference between DB2 and Oracle

DB2 and Oracle are two popular database management systems (DBMS). Though both are DBMS, there are differences between the two. DB2 is a relational database management system (RDBMS) developed by IBM. It is mainly used on mainframe platforms, though it is also available for Linux, UNIX, and Windows operating systems. Oracle, on the other hand, is a multi-model DBMS developed by Oracle Corporation. It runs on most major platforms, including Linux, UNIX, and Windows. One key difference between DB2 and Oracle is that DB2 supports multiple data models, while Oracle only supports the relational model. This means that DB2 can be used to manage not only relational data, but also XML, graph, and object-oriented data. Another difference is that DB2 uses an optimizer to choose the best access plan for each query, while Oracle uses cost-based optimizers that consider factors such as CPU usage and I/O costs when choosing an access plan. Finally, DB2 offers a number of features that are not available in Oracle, such as automatic storage management and atomic commits.


The two databases, DB2 and Oracle, are both powerful tools for businesses. They have different features that may make one more advantageous for your company than the other.
