OLE（Object Linking and Embedding，对象链接与嵌入），是能让应用进程创建包含不同来源的复合文档的一项技术。OLE不仅是桌面应用进程集成，而且还定义和实现了一种允许应用进程作为软件“对象”（数据集合和操作数据的函数）彼此进行“链接”的机制，这种链接机制和协议称为部件对象模型(Component Object Model),简称COM。OLE可以用来创建复合文档，复合文档包含了创建于不同源应用进程，有着不同类型的数据，因此它可以把文本、声音、图像、表格、应用进程等组合在一起。

Object Linking and Embedding (OLE, sometimes pronounced /oˈlɛj/) is a proprietary technology developed by Microsoft that allows embedding and linking to documents and other objects. For developers, it brought OLE Control Extension (OCX), a way to develop and use custom user interface elements. On a technical level, an OLE object is any object that implements the IOleObject interface, possibly along with a wide range of other interfaces, depending on the object's needs.
