Synology Disk Replacement DS107e

The course Databases and SQL hosted by Developpez.com is doing well. Since it went online in 2007, it totals more than 441,000 page views, or about 500 visits per day. This interest gave me the motivation to continue my effort to improve course material. This new version is published this month in the collection of Ellipses + Info. I'll talk soon in a new ticket . I want to thank editions Ellipses for allowing me to keep the first blank line on the site Developpez.com. This online version is currently being updated. I can make few changes in order not to overshadow the published version. So I fixed some mistakes, removed the topics of exercise (they have little value without the correction) and cropped images. is what brings the version published in relation to the version Developpez.com online at:

New concepts (specialization, connection identifier, validity of a type n-ary association, aggregate functions and SQL operators, user functions, PL / pgSQL, triggers ...). The edited version is 2.5 times larger than the online version (in number of sentences and number of figures).

sessions, tutorials and practical work accompanied by full and detailed answer keys.

Many improvements (corrections, illustrations, examples ...). In fact, only 10% of the edited version is found in identical form in the version Online.
A much more pleasant presentation in the form of a real book.
