# odb-examples - ODB compiler usage examples
This package contains examples of using `odb`, object-relational mapping (ORM)
compiler for C++. The following list gives an overview of the available
examples. See the `README` file accompanying each example for more
information. See `odb-tests/README.md` for instructions on setting up various
databases to run these examples.
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.
