Do you have to get a PhD?

The doctorate is a reference diploma, particularly at the international level. It opens the way for its holder to numerous professional opportunities (Management of R&D departments, teaching, etc.). Also, for several decades now, many doctorates have been offered in higher education institutions that have an active research policy. This book is a non-exhaustive synthesis of the various existing doctorates (research doctorate, professional doctorate, through publications or insertion of articles, etc.). The objective through this book is to invite young and old alike to complete a thesis in order to obtain a doctorate (it is a stimulating experience). It should be noted that all the information contained in this non-exhaustive synthesis is on the Internet (the only channel for the sources of the work).
