It provides a structured representation of the document (a tree) and it defines a way that the structure can be accessed from programs so that they can change the document structure, style and content. The DOM provides a representation of the document as a structured group of nodes and objects that have properties and methods. Essentially, it connects web pages to scripts or programming languages. Though often accessed using JavaScript, the DOM is not part of it and it can be used by other languages, though this is much less common. An introduction to the DOM is available.
