问题：
What is the difference between a framework and a library ? 框架和库有什么区别？
I always thought of a library as a set of objects and functions that focuses on solving a particular problem or a specific area of application development (ie database access); 我一直认为库是一组对象和函数，专注于解决特定问题或应用程序开发的特定领域（即数据库访问）; and a framework on the other hand as a collection of libraries centered on a particular methodology (ie MVC) and which covers all areas of application development. 另一方面，框架是一个以特定方法（即MVC）为中心的图书馆集合，涵盖了应用程序开发的所有领域。
