If all functions are static, we don't need a class. I'd create db_factory
namespace here instead.

http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Nonmem...

Rather than creating classes only to group static member functions which do not
share static data, use namespaces instead.

Done.

+ public:
+  static scoped_ptr<GDataDB> CreateGDataDB(const FilePath& db_path);

if we are to use the class, we should have private: and
DISALLOW_COPY_AND_ASSIGN. namespace is more concise. :)

Done.
