The DBA degree is the highest degree a student can obtain in a business discipline, according to the college website Education-Portal. DBA students may specialize in a number of business fields, such as accounting, management information systems, entrepreneurism and strategic leadership.
To qualify for a DBA degree, according to the school of business at California Southern University, students must complete at least 60 graduate, post-master's degree credit hours. This requirement may vary from school to school.
Although the DBA degree is one step further than a master of business administration, or MBA, degree, the education website Eduers notes that the DBA has a much stronger focus on teaching and research than other business degrees. In addition, DBA students also focus on practical business applications more than the philosophical pursuits common to a Ph.D. degree.
