• Document libraries

Drawbacks in Sharepoint 2001

SharePoint 2010

• An evolved version of MOSS 2007
• Microsoft SharePoint Foundation (SPF) 2010 (Renamed WSS)
• Microsoft SharePoint Server (SPS) 2010
• Requires a 64 bit OS - Runs only on 64 bit
• Built on .Net 3.5 SP1
• Can be installed on client OS for development

Farms

• Farm can be single server or multi server
• Exactly one configuration database
• Farm requires Web server(s) and database server
• Single Server Farm
• Medium Server Farm
• Large Server Farm

A sharepoint farm is simply a collection of servers that have sharepoint installed on them and are all connected to the same configuration database.

Web Applications

Every SharePoint Web applicatin runs as one large ASP.NET application. A sharepoint farm typically runs two or more web applications. Each web application has one or more content database. Web application security configured independently.

The introduction of claims-based security support into SharePoint 2010 provides developers with new possibilities for configuring a Web application. One such possibility is the ability to outsource identity management to an identity service publicly available on the Internet, such as Windows Live ID. This approach gives developers the ability to track users for the purposes of security, auditing, and personalization but without the hassles of setting up a user database, storing credentials, and dealing with all the associated password management headaches.

Service Applications

• Replacement of Shared Service Providers (SSPs)
• facilitates sharing resources across sites running in different web applications and different farms
• Can run on Web Front End Server (WFE) or Application Serveri
• Web applications can be assoicated with different service offerings 

Site Collections and Sites

A site is a storage container that allows users to store and manage content such as list items and documents. In addition, a site is a customizable entity that allows users to add pages, lists, and child sites. In conclusion, a site is a securable entity whose content is accessible to a configurable set of users.

• Sites are partitioned into site collections
• Site collection contains a top level site
• Site collection may contain hierarchy of child sites
• Web application can support thousands of site collections
• SharePoint 2010 introduces big changes to UI
• Master page has been changed
• Ribbon
• 
• Home page is wiki page
• Avoided unnecessary post backs
• A new Ajax-powered user interface
