The degree of Doctor of Business Administration (abbreviated DBA or D.B.A. and equivalent to PhD in Business Administration), is a research doctorate in business administration. The D.B.A. requires coursework and research beyond the masters degree that normally results in a dissertation and possible journal publication that contributes to business practice.
The D.B.A. is equivalent to a PhD in Business Administration. The D.B.A. tends more towards applied research rather than theoretical research, especially during the thesis writing phase.
