Catel et Bocquet retracent le destin de la fascinante Joséphine Baker dans un magnifique roman (bio)graphique tout en noir et blanc. En 500 pages, les auteurs nous dévoilent toutes les facettes de cette femme emplie de convictions : muse de nombreux artistes, militante contre la ségrégation raciale, agent du contre-espionnage de la France Libre, mère adoptive d’une douzaine d’enfants venus d’horizons divers… elle était décidément bien plus qu’une danseuse de cabaret affublée d’une ceinture de bananes...
This book sheds light on the principles behind the relational model, which is fundamental to all database-backed applications--and, consequently, most of the work that goes on in the computing world today. Database in Depth: The Relational Model for Practitionersgoes beyond the hype and gets to the heart of how relational databases actually work.
Ideal for experienced database developers and designers, this concise guide gives you a clear view of the technology--a view that's not influenced by any vendor or product. Featuring an extensive set of exercises, it will help you:
- understand why and how the relational model is still directly relevant to modern database technology (and will remain so for the foreseeable future)
- see why and how the SQL standard is seriously deficient
- use the best current theoretical knowledge in the design of their databases and database applications
- make informed decisions in their daily database professional activitiesDatabase in Depthwill appeal not only to database developers and designers, but also to a diverse field of professionals and academics, including database administrators (DBAs), information modelers, database consultants, and more. Virtually everyone who deals with relational databases should have at least a passing understanding of the fundamentals of working with relational models.
Author C. J. Date has been involved with the relational model from its earliest days. An exceptionally clear-thinking writer, Date lays out principle and theory in a manner that is easily understood. Few others can speak as authoritatively the topic of relational databases as Date can.

He enjoys a reputation that's second to none for his ability to explain complex technical issues in a clear and understandable fashion. His previous books for O'Reilly include SQL and Relational Theory (2nd edition); Database Design and Relational Theory; and View Updating and Relational Theory.
