+This example shows how to map persistent C++ classes to a custom database
+schema. In particular, it shows how to map all the commonly-used constructs,
+including containers, object relationships, and composite value types.
+
+The example consists of the following files:
+
+employee.hxx
+ Header file defining the 'employee' and 'employer' persistent classes
+ as well as the 'name' composite value type. ODB pragmas are used to
+ assign custom database tables to persistent classes as well as custom
+ database types and columns to data members.
+
+employee-odb.hxx
+employee-odb.ixx
+employee-odb.cxx
+ These files contain the database support code for the employee.hxx header
+ and are generated by the ODB compiler from employee.hxx using the following
+ command line:
+
+ odb --std c++11 -d <database> --generate-query --generate-session \
+ --default-pointer std::shared_ptr employee.hxx
+
+ Where <database> stands for the database system we are using, for example,
+ 'pgsql'.
+
+ The --generate-session option is used to enable session support for all
+ the persistent classes in employee.hxx. The --default-pointer option is
+ used to make std::shared_ptr the default object pointer.
+
+database.hxx
+ Contains the create_database() function which instantiates the concrete
+ database class corresponding to the database system we are using.
+
+driver.cxx
+ Driver for the example. It includes the employee.hxx and employee-odb.hxx
+ headers to gain access to the persistent classes and their database support
+ code. It also includes database.hxx for the create_database() function
+ declaration.
+
+ In main() the driver first calls create_database() to obtain the database
+ instance. It then programmatically creates the database schema by executing
+ a series of SQL statements. After that the driver creates a number of
+ 'employee' and 'employer' objects, sets the relationships between them,
+ and persists them in the database. Finally, the driver performs a database
+ query and prints the information about the returned objects.
+
+To compile and link the example manually from the command line we can use the
+following commands (using PostgreSQL as an example; replace 'c++' with your
+C++ compiler name):
+
+c++ -c employee-odb.cxx
+c++ -DDATABASE_PGSQL -c driver.cxx
+c++ -o driver driver.o employee-odb.o -lodb-pgsql -lodb
+
+To run the driver, using PostgreSQL as an example, we can execute the
+following command:
+
+./driver --user odb_test --database odb_test
+
+Here we use 'odb_test' as the database login and also 'odb_test' as the
+database name.

+This example shows how to generate and use a database schema that is embedded
+into the application rather than stored as a separate SQL file.
+
+The example consists of the following files:
+
+person.hxx
+ Header file defining the 'person' persistent class.
+
+person-odb.hxx
+person-odb.ixx
+person-odb.cxx
+ These files contain the database support code as well as the embedded
+ database schema for the person.hxx header. They are generated by the ODB
+ compiler from person.hxx using the following command line:
+
+ odb --std c++11 -d <database> --generate-schema --schema-format embedded \
+ --generate-query person.hxx
+
+ Where <database> stands for the database system we are using, for example,
+ 'pgsql'.
+
+ The --generate-schema option requests the generation of the database schema.
+ The --schema-format option is used to instruct the ODB compiler to embed the
+ schema into the generated C++ files. It is also possible to generate the
+ schema creation code into a separate source file by passing the 'separate'
+ value instead of 'embedded' to the --schema-format option. This is primarily
+ useful if you want to place the schema creation functionality into a
+ separate program or library.
+
+database.hxx
+ Contains the create_database() function which instantiates the concrete
+ database class corresponding to the database system we are using.
+
+driver.cxx
+ Driver for the example. It includes the person.hxx and person-odb.hxx
+ headers to gain access to the persistent classes and their database support
+ code. It also includes database.hxx for the create_database() function
+ declaration.
+
+ In main() the driver first calls create_database() to obtain the database
+ instance. It then uses the ODB schema catalog to create the database
+ schema. During this step the generated code issues a number of SQL
+ statements that drop and create necessary database tables, etc.
+
+ After the database schema is ready, the driver persists a number of 'person'
+ objects, performs a database query, and prints the information about the
+ returned objects.
+
+To compile and link the example manually from the command line we can use the
+following commands (using PostgreSQL as an example; replace 'c++' with your
+C++ compiler name):
+
+c++ -c person-odb.cxx
+c++ -DDATABASE_PGSQL -c driver.cxx
+c++ -o driver driver.o person-odb.o -lodb-pgsql -lodb
+
+To run the driver, using PostgreSQL as an example, we can execute the
+following command:
+
+./driver --user odb_test --database odb_test
+
+Here we use 'odb_test' as the database login and also 'odb_test' as the
+database name.
