ODB is an object-relational mapping (ORM) system for C++. It provides
tools, APIs, and library support that allow you to persist C++ objects
to a relational database (RDBMS) without having to deal with tables,
columns, or SQL and without manually writing any of the mapping code.
For more information see:
http://www.codesynthesis.com/products/odb/
This package contains the ODB examples. The following list gives an
overview of the available examples. See the README file accompanying
each example for more information.
Note also that most of the examples use the --table-prefix ODB compiler
option to assign a unique prefix to tables created by each example. This
is done to allow examples to run against the same database without
causing any schema conflicts. You don't have to use this option in your
own applications.
hello
A "Hello World" example that shows how to use ODB to perform basic
database operations.
query
Shows how to use the ODB Query Language to search the database for
persistent objects matching certain criteria.
composite
Shows how to declare and use composite value types.
container
Shows how to use containers as data members in persistent objects.
relationship
Shows how to declare and use unidirectional to-one and to-many
relationships.
inverse
Shows how to declare and use bidirectional one-to-one, one-to-many, and
many-to-many relationships.
inheritance/reuse
Shows how to use reuse inheritance with ODB.
inheritance/polymorphism
Shows how to use polymorphism inheritance with ODB.
section
Shows how to use object sections to implement lazy-loading and change-
updating of a subset of data members in a persistent class.
view
Shows how to define and use object, table, mixed, and native views.
prepared
Shows how to use prepared queries.
optimistic
Shows how to use optimistic concurrency in ODB.
pimpl
Shows how to use virtual data members to implement a persistent class that
employs the pimpl C++ idiom.
c++11
Shows how to use ODB with C++11.
access
Shows various approaches used by ODB to access data members that cannot be
accessed directly.
boost
Shows how to persist objects that use Boost smart pointers, containers,
and value types with the help of the Boost profile library (libodb-boost).
qt
Shows how to persist objects that use Qt smart pointers, containers, and
value types with the help of the Qt profile library (libodb-qt).
schema/embedded
Shows how to generate and use a database schema that is embedded into the
application.
schema/custom
Shows how to map persistent C++ classes to a custom database schema.
mapping
Shows how to customize the mapping between C++ value types and database
types.
