Approaches that are illustrated by this +example include the automatic discovery of suitable accessor/modifier +functions, explicit specification of the accessor/modifier functions, +explicit specification of more complex accessor/modifier expressions, and +use of virtual data members. + +The example consists of the following files: + +person.hxx + Header file implementing the 'person' persistent class. + +person-odb.hxx +person-odb.ixx +person-odb.cxx +person.sql + The first three files contain the database support code and the last file + contains the database schema for the person.hxx header. + + These files are generated by the ODB compiler from person.hxx using the + following command line: + + odb -d <database> --generate-query --generate-schema person.hxx + + Where <database> stands for the database system we are using, for example, + 'mysql'. + +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 class and its 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.
