The two degrees Master of Business Administration (MBA) and Doctor of Business Administration (DBA) Looks as if same and there are some companies which also indeed treat both an MBA and a doctoral program as equally valuable qualification of an employee but there is a difference between two below I am telling you the difference

The MBA is a general management degree with a strong practical approach. It provides an overview on the most important managerial functions and trains you in solving practical business problems. Full-time programs often include leadership seminars as well as practical periods such as business plan development, in-company projects, or internships, and your primary source of information is case studies.

In contrast, the DBA is a research program where you read academic journals. You become trained not in solving managerial problems but in becoming a researcher who is able to publish in academic journals some day.

MBA full-time and part-time students typically are business professionals who want to develop their career in business. The core reasons for doing an MBA degree program are: increase your career options inside and outside your current employer; qualify for a leadership position; acquire managerial knowledge, for instance after you have become promoted; and acquiring knowledge and building a network for developing your own business

DBA students, in contrast, are business professionals who look for a personal challenge and want to acquire the qualification as a researcher. They already have a successful business career behind them and may already have acquired an MBA - now they want to complement their knowledge as a practitioner by becoming a scholar and move between the business and the academic world. They are rather broadening and extending their capability profile than deepening their existing knowledge base.

As a summary I will say by obtaining a doctoral degree in business, professionals learn how to do research whereas in the MBA they learn to become a better manager.
