CAML stands for Collaborative Application Markup Language and is an XML-based language
that is used in Microsoft Windows SharePoint Services to define sites and lists, including, for
example, fields, views, or forms, but CAML is also used to define tables in the Windows
SharePoint Services database during site provisioning.

A view may be thought of as a virtual table, that is, a table that does not really exist in its own right but is instead derived from one or more underlying base table. In other words, there is no stored file that direct represents the view instead a definition of view is stored in data dictionary.

Growth and restructuring of base tables is not reflected in views. Thus the view can insulate users from the effects of restructuring and growth in the database. Hence accounts for logical data independence.

It specifies user views and their mappings to the conceptual schema.

A command is a special type of message. Windows generates a command whenever user chooses a menu item, clicks a button or tells the system to do something. Windows send a WM_COMMAND message for menu choices, button clicks or WM_NOTIFY for list box selection. Commands and notifications are passed around by the operating system just like any other message until they get into the top of OnWndMsg() and MFC command routing starts.Command messages have the first parameter, the resource id of the menu item that was chosen or the button that was clicked.Command routing is a mechanism used by OnWndMsg to send commands to objects that can't receive messages. Only objects of type CWnd can receive messages but all objects that inherit from CCmdTarget including CWnd and CDocument can receive commands and notifications.How do commands and notifications get to the class though? The answer is by command routing. OnWndMsg calls CWnd::OnCommand() or CWnd::OnNotify() which in turn call OnCmdMsg() which is a virtual function, which means that different command targets have different implementations. The implementation of a frame window sends the commands to its views and documents. This is how commands get handled by m

The document view architecture was introduced in MFC 2.0. In this architecture the application's data is represented as a "document" object and the views of this data are represented as "view" objects. E.g. If you create an excel document what you see to get your job done i.e. cells, values, etc comprises the view and when you save this data it gets saved as a document. The various views of this document is as a table, graphs, bar charts, etc. The data is stored in a document object. The class representing the document object is CDocument. The sole purpose of this class is to manage an application's data. Views server two purposes: renders visual representation of data stored in document and translate the user's inputs into commands that operate on the data in the document. The class for view is CView. Thus the division of work in terms of data and view helps in work division, better productivity and reusability of code.
