[单选题]请根据下面叙述的场景选用适当的设计模式。若某面向对象系统中的某些类有且只有一个实例，那么采用()设计模式能够有效达到该目的；该系统中的某子模块需要为其他模块提供访问不同数据库系统(Oracle、SQLServer、DB2UDB等)的功能，这些数据库系统提供的访问接口有一定的差异，但访问过程却都是相同的，例如，先连接数据库，再打开数据库，最后对数据进行查询，()设计模式可抽象出相同的数据库访问过程；系统中的文本显示类(TextView)和图片显示类(PictureView)都继承了组件类(Component)，分别显示文本和图片内容，现需要构造带有滚动条、或者带有黑色边框、或者既有滚动条又有黑色边框的文本显示控件和图片显示控件，但希望最多只增加三个类，()设计模式可以实现该目的。

[多选题]● At a basic level, cloud computing is simply a means of delivering IT resources as（71）．Almost all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking, Programming tools, even communication services and collaboration（72）．Cloud computing began as large-scale Internet service providers such as Google, Amazon, and others built out their infrastructure. An architecture emerged: massively scaled, （73）distributed system resources, abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on（74）"somewhere on the Internet" and the application runs on both the "cloud servers" and the user's browser.
A. Both clouds and grids are built to scale horizontally very efficiently. Both are built to withstand failures of （75） elements or nodes. Both are charged on a per-use basis. But while grids typically process batch jobs, with a defined start and end point, cloud services can be continuous. What's more, clouds expand the types of resources available - file storage, databases, and Web services - and extend the applicability to Web and enterprise applications.
