I have a large project with a driver part and about 5 libraries doing various associated tasks. Many of the libraries require access to 'global' configuration data which is read from a database at startup by the driver code. By driver I just mean the part which contains the main function.

My idea on how to handle this was to create a config class with a static method to get the config items. Is this the best approach? How else could this be achieved?

eg:

class config { public: static get_item(key); private: static values; }; 

The class itself would not be static so each code component using it would create its own instance of the class, but I can't see a way round that. Is singleton design appropriate here?
