LiteSQL is a C++ library that integrates C++
objects tightly to a relational database and thus
provides an object persistence layer. LiteSQL
supports SQLite3, PostgreSQL, and MySQL as
backends. LiteSQL creates tables, indexes, and
sequences to database and upgrades schema when
needed. In addition to object persistence, LiteSQL
provides object relations which can be used to
model any kind of C++ data structures. Objects can
be selected, filtered, and ordered using a
template- and class-based API with type checking
at compile time.
