Example 6: complex searches and foreign keys
See source code.
This program illustrates some advanced techniques that can be applied for
complex data structures using multi_index_container. Consider a car_model
class for storing information about automobiles. On a first approach,
car_model can be defined as:
struct car_model
{
std::string model;
std:string manufacturer;
int price;
};
This definition has a design flaw that any reader acquainted with relational
databases can easily spot: The manufacturer member is duplicated among all
cars having the same manufacturer.
--- This definition also has a syntax error that any C++ programmer can easily spot! :) Mike
