DBA is a database administrator, and English is a database administrator.

2.DBA doctor of business administration

The highest degree in management.

First of all, MBA (Master of Business Administration) and EMBA (executive master of business administration) are master's degrees, while PhD (Doctor of Philosophy: now involving philosophy, politics, economy and other disciplines) and DBA (Doctor of Business Administration) are doctoral degrees, which are different in the level and difficulty of research.

In Europe, some experts predict that the development prospect of DBA education is very optimistic, which may one day break the situation that the traditional PhD model of doctoral education dominates the world. Like PhD, DBA is an authentic American degree. For example, Harvard Business School offers both doctoral and DBA programs. In the European Union, Britain is always the fastest following the United States, so many universities in Britain have set up DBA courses.

Grenoble Graduate School of Business-GGSB is the earliest and only business school offering DBA courses in France. In fact, Henry School of Management, one of the partners of its DBA program, is also one of the first famous universities in Britain to offer DBA courses.

Theory and practice are closely integrated.

The traditional doctoral model is generally 4-5 years of full-time doctoral study, focusing on pure theoretical research. Generally speaking, it does not focus on the business field, but focuses more on management and economy, engaged in teaching and research. And DBA education is more related to business practice, focusing on the effect of applying theory to practice. Although the educational system of DBA in Europe is generally 4-5 years, students are studying part-time instead of full-time. Like PhD, DBA requires students to choose a research topic from the beginning. Knowledge topics themselves are mostly practical problems faced by students in their own work, which is more practical.

Compared with the traditional doctor training in China, the teaching feature of DBA is the closer combination of theory and practice. If the usual intensive teaching method of MBA is compared to the process of "eating", then the course of DBA is like the process of "digestion". Using the method of cultivating doctoral students in Europe and America, this paper systematically studies the problems faced by students in their own jobs, improves the management innovation ability and new project decision-making optimization ability of senior managers of the company, so as to adapt to the rapidly changing business environment after China's entry into WTO and make forward-looking strategic choices.

At present, most EMBA courses in China are expensive, but they are widely used in enrollment, which is suspected of uneven quality. Some EMBA courses are often attended by nearly 100 students in a class, and the curriculum is mainly in the form of lectures. No wonder some media pointedly call it "a diploma plus a series of lectures".

Who will go to DBA?

The target of DBA teaching is mostly talents with MBA, EMBA or equivalent master's degree, and at least 5 ~ 6 years of solid work experience is the necessary capital. Because the overall quality of students is relatively high, small class teaching is adopted to strictly ensure the high quality of teaching.

Professor Wu Jianwei, deputy dean of the School of Economics and Management of Tongji University, told the author that students who come to study DBA can be roughly divided into three categories: the first category is university professors and doctoral students, who value the close integration of DBA projects with teaching and scientific research; The second category is business people, who are also the main force in learning DBA. They come from different fields, such as science and technology management, financial analysis, network security, information software, etc., in order to seek specific solutions for enterprises. The third category is consulting professionals, because learning DBA is a good opportunity to know customers and look for opportunities. In addition, in foreign countries, government officials, non-profit organizations and charitable organizations will also choose DBA.

Relatively speaking, the entry requirements of DBA are not high: students must have a master's degree in MBA or related fields and at least 6 years of work experience, but due to the restriction of enrolling 10 ~ 15 students each semester, the application is much more difficult. It is understood that in 2002, 42 CEOs of famous enterprises at home and abroad formally signed up for the first DBA project. After strict screening, only 10 students were enrolled. Among these students are the general managers of international enterprises, the presidents of listed companies, the bosses of state-owned enterprises and private entrepreneurs, all of whom are senior managers of some domestic enterprises, with a low starting point. The words of a general manager of a company studying DBA course in Gornobel Business School are very representative. "I studied MBA 65,438+00 years ago, and now I really want to go back to school for further study and further improve my theoretical knowledge to guide my work. However, I am 40 years old. In the past, the doctoral program only focused on PhD, which didn't help me much in my practical work, so I had to resign. DBA can better meet my needs. I learned a lot of the latest practical business skills in finance and strategic management and applied them to my work at the same time. "
