Editor's Notes
- #5: Here is an overall view of the SharePoint data technologies platform. Developers can make use of these technologies to build SharePoint applications. SharePoint 2010 introduces more additions to the already available SharePoint 2007 technologies.Explain the client side and server side framework:Client OMREST APIsSPLINQ
- #7: Microsoft SharePoint Foundation offers a highly structured server-side object model that makes it easy to access objects that represent the various aspects of a SharePoint Web site. From higher-level objects, you can drill down through the object hierarchy to obtain the object that contains the members you need to use in your code.
- #8: Sample custom application: You may want to create custom .aspx pages and Web applications and store them in a location that is accessible from all Web sites in your Microsoft SharePoint Foundation 2010 deploymentDeveloper writes code (.aspx.cs) using the Server OMServer OM interacts with the SharePoint site, retrieves the data from the SharePoint siteThe .aspx page displays the SharePoint data
