Database Management Systems (DBMS) play a vital role in storing, organizing, and managing data across various industries. They can be broadly classified into commercial (proprietary) and open-source systems. Commercial DBMS are developed by companies and require paid licenses, offering strong technical support, high security, and scalability for enterprise-level applications. Open-source DBMS, on the other hand, are freely available and customizable, making them ideal for developers, startups, and educational purposes. Both types are essential in modern data-driven environments—supporting banking, e-commerce, research, and cloud computing. Below are the uses of six commercial and six open-source DBMS in detail.
