Detailed Description

This class provides a thin wrapper around database connections using QSqlDatabase.

QSqlDatabase objects are created based on a common base connection name. A unique suffix is added to each connection name based on the calling thread. All connection instances with the same base name and calling thread are shared. The returned QSqlDatabase objects must not be passed between threads. This class also assumes that no function calls to QSqlDatabase that are not thread-safe are performed elsewhere.
