While NoSQL may be getting all the buzz, in many cases an old fashioned relational database, such as MySQL, may work just as well if not better.

Le théorème CAP ou CDP, aussi connu sous le nom de théorème de Brewer dit qu'il est impossible sur un système informatique de calcul distribué de garantir en même temps les trois contraintes suivantes[1],[2] : D'après ce théorème, un système de calcul distribué ne peut garantir à un instant T que deux de ces contraintes mais pas les trois[3]. Le théorème part d'une conjecture énoncée par le chercheur en informatique Eric Brewer de l'université de Californie à Berkeley lors du Symposium on Principles of Distributed Computing (PODC, « Symposium sur les principes d'informatique distribuée »)[4]. En 2002, Seth Gilbert et Nancy Lynch du MIT publient une preuve formelle de la vérifiabilité de la conjecture de Brewer, et en font un théorème établi[1].

I sometimes read that NoSQL solutions are a better fit for prototyping applications as they don’t require any upfront data modeling work. I must confess that I pretty much disagree with that.

"MyBatis Schema Migration System (or MyBatis Migrations for short) seeks to: Work with any database, new or existingLeverage the source control system (e.g. Subversion)Enable concurrent developers or teams to work independentlyAllow conflicts very visible and easily manageableAllow for forward and backward migration (evolve, devolve respectively)Make the current status of the database easily accessible and comprehensibleEnable migrations despite access privileges or bureaucracyWork with any methodologyEncourages good, consistent practices"

Article assez inspirant. Plutôt qu'un sémaphore je testerais bien un système comme SqlLite pour stocker des paires clé-valeur sur disque et les manipuler en mémoire.
