I work at Revolv, and right now we're just about finished with a major migration off of a NoSQL database. We're moving onto a traditional RDBMS (PostgreSQL, to be precise). Many people seem surprised that we, a tech-savvy startup, would be moving to an "old" technology. But in fact our reasoning is pretty simple: A relational system better meets our needs and is more cost-effective. There are three main reasons why I say this.

I recently worked on an uncommon slow query: less than 100 rows were read and returned, the whole dataset was fitting in memory but the query took several seconds to run.

Un trigger (déclencheur en français) est un objet de base de données qui s’active à un moment spécifié à sa création. Il est associé à une table et peut être déclenché avant ou après un évènement particulier.
Il existe 3 types d’évènements qui déclenche un trigger qui sont: INSERT, UPDATE et DELETE. Les déclencheurs sont souvent utilisés pour créer des audits, s’assurer de l’intègrité référentielle des données, éviter la perte d’informations en interceptant les données supprimées suite à un delete accidentel ou pas.

Popular myth : MyISAM is faster than InnoDB in reads, as InnoDB is transactional, supports Foreign Key and has an operational overhead. As you will see it is not always true.

"We need a database that 'just works' and runs at 'web scale.'" MySQL software developers are under pressure to do more in less time, and create applications that adapt to ever-changing requirements. But it's true that some of a developer's time is wasted when their method of optimizing involves trying every combination of code and index definition. There must be a more straight path to achieve the best database code. This talk shows you some of these methods, including: - How to find out which indexes are the best fit for your MySQL application
- How to protect yourself from the number one MySQL database security vulnerability on the web
- How to decide when to optimize a MySQL database application with denormalization, indexes, caching, partitioning, sharding

Doivent-ils continuer à les mettre en œuvre sans nouveau texte ? L’invalidation de la directive va, après les élections européennes, conduire à un nouveau texte qui devra, respecter les indications fournies par l’arrêt.
Une discussion va devoir s'engager notamment sur le type de données pouvant être conservé, les personnes concernées et celles ayant accès auxdites données, le contrôle pour savoir si les données conservées ne dépassent pas ce qui est autorisé.
Cette discussion aura des conséquences sur le plan technique, dès lors qu'il ne s'agira plus de collecter de façon indifférenciée des données en masse mais qu'il faudra, pour les fournisseurs de communications électroniques, arriver à distinguer les données qu'ils auront le droit ou l'obligation de conserver.
Il va donc leur falloir modifier leur architecture logicielle mais également démontrer que la sécurité de la conservation des données est assurée, ce qui est l'une des interrogations de la Cour.
