qDBManager is a lightweight Qt/C++ data access layer for SQLite with an entity-oriented API.

It was designed for projects that want ORM-like ergonomics without external heavy dependencies.

• Basic CRUD operations
• Entity registration and mapping
• Criteria-based search helpers
• SQLite adapter included (interfaces/qsqlite.h)

Add qdbmanager.pri to your Qt .pro file:

include(../qdbmanager/qdbmanager.pri)

qDBManager provides macros to simplify entity mapping:

• Q_FIELD(type, name): mapped DB field
• Q_TRANSIENT_FIELD(type, name): non-persisted field
• Q_INDEX(field): single-field index
• Q_INDEX_MUL(field1, field2): multi-field index

QDBManager* dbm = QDBManager::create("test", "QSQLITE");
dbm->register_entity<TestEntity>();

dbm->openDB("testdb.sqlite");
dbm->createTable<TestEntity>();

TestEntity* entity = new TestEntity();
entity->set_name("Leonard");
entity->set_surname("Hofstadter");

dbm->insertOrUpdate<TestEntity>(entity);
QListTestEntity items = dbm->listAll<TestEntity>();

dbm->closeDB();

Important: always call register_entity<YourEntity>() before loading entities.

• Current adapter support is SQLite only.
• Additional adapters can be implemented by extending QDBManager.
