Q. How Does SharePoint work?
Ans. The
browser sends a DAV packet to IIS asking to perform a document check in.
PKMDASL.DLL, an ISAPI DLL, parses the packet and sees that it has the
proprietary INVOKE command. Because of the existence of this command, the packet
is passed off to msdmserv.exe, who in turn processes the packet and uses EXOLEDB
to access the WSS, perform the operation and send the results back to the user
in the form of XML.
Q. What is
CAML?
Ans. CAML stands for
Collaborative Application Markup Language and is an XML-based languagethat is
used in Microsoft Windows SharePoint
Services to define sites and lists, including, for Eg, fields, views, or forms,

database during site provisioning. Developers mostly use CAML Queries to
retrieve data from Lists\libraries.
Q. Can you
display\add a Custom aspx or WebApplication Page in SharePoint Context

display it in SharePoint Context. Firstly, add the references for various
sharepoint assemblies on the Page. Then wrap the Code in PlaceHolderMain
contentPlaceholder, so that it gets displayed as a content page. Lastly, add a
reference to SharePoint Master Page in aspx file and swicth it in Code behind if
