QxOrm est une bibliothèque C++ disponible sous une double licence :
- licence GNU/GPLv3 : open-source et gratuite (idéale pour développer un projet open-source ou pour une évaluation de la bibliothèque QxOrm) ;
- licence propriétaire permettant de distribuer une application basée sur la bibliothèque QxOrm sans les restrictions de la licence GNU/GPLv3.
|

QxOrm library has been accepted into the Qt Ambassador Program

QxEntityEditor est un éditeur graphique pour la bibliothèque QxOrm : QxEntityEditor permet de gérer graphiquement le modèle d'entités.
QxEntityEditor est multi-plateforme (disponible pour Windows, Linux et Mac OS X) et génère du code natif pour tous les environnements : bureau (Windows, Linux, Mac OS X), embarqué et mobile (Android, iOS, Raspberry Pi, etc.).
Remarque : par défaut, l'application QxEntityEditor est limitée à 5 entités par projet.
Pour obtenir une clé de licence et ainsi créer un nombre illimité d'entités par projet, vous pouvez nous contacter à l'adresse suivante : contact@qxorm.com.
Une vidéo de présentation de l'application QxEntityEditor est disponible.
Prix d'une licence QxEntityEditor : 300€ (par développeur, mise à jour gratuite pendant 12 mois).
QxOrm est dépendant des excellentes bibliothèques
boost (compatible à partir de la version 1.38) et
Qt
(compatible à partir de la version 4.5.0).
Vous devez donc télécharger et installer ces 2 bibliothèques avant de pouvoir utiliser QxOrm.

boost : de nombreux modules de la
bibliothèque boost font partie de la nouvelle norme C++.
C'est une bibliothèque reconnue pour sa qualité, son code 'C++
moderne', sa documentation, sa portabilité, etc...
QxOrm utilise les fonctionnalités suivantes de boost :
smart_pointer, serialization, type_traits,
multi_index_container, unordered_container, any, tuple,
foreach, function.
Il est conseillé d'installer et d'utiliser la dernière version
de boost disponible à l'adresse suivante : http://www.boost.org/ |
 |
Qt : bibliothèque complète : IHM
(QtGui), réseau (QtNetwork), XML (QtXml), base de données
(QtSql), etc...
La documentation est excellente et le code C++ écrit à partir
de cette bibliothèque est à la fois performant et simple de
compréhension.
Depuis le rachat par Nokia puis Digia et sa nouvelle licence LGPL, Qt est
sans contexte la bibliothèque phare du moment.
QxOrm est compatible avec les principaux objets définis par Qt
: QObject, QString, QDate, QTime, QDateTime, QList, QHash,
QSharedPointer, QScopedPointer, etc...
Il est conseillé d'installer et d'utiliser la dernière version
de Qt disponible à l'adresse suivante : http://qt.digia.com/ |
