The document presents a comprehensive overview of SharePoint data technologies, focusing on the new capabilities of the list platform and various methods to interact with SharePoint data using technologies like LINQ, client object models, and RESTful services. It details improvements in SharePoint 2010, including list validation, relationships, and the development of client applications using JavaScript and Silverlight. Additionally, it provides example codes and deployment strategies, aiming to educate developers on building applications leveraging these data technologies.

6. Lists and LookupsLookupLookupProjectsEmployeesClientsm1m1Lookups form relationships between listsOne-to-manyMany-to-many

7. List RelationshipsEnforce Data IntegrityOne-to-many relationships can be used to:Trigger cascade deleteRestrict deleteRelationship behaviors (delete/restrict) are not supported on multi-value lookups

8. List ValidationValidation Formula can be specified on List and Columns=[Column1]-[Column2]=AND([Column1]>[Column2], [Column1]<[Column3])=PRODUCT([Column1],[Column2],2)=DATEDIF([Column1], [Column2],"d")=CONCATENATE([Column2], ",", [Column1])

9. Large ListsSet a limit for how many rows of data can be retrieved for a list or library at any one time:List View ThresholdList View Threshold for Auditors and AdministratorsList View Lookup ThresholdDaily Time Window for Large QueriesIf enabled on the Web Application, developer can turn off throttling using:SPQuery.RequestThrottleOverrideSPSiteDataQuery.RequestThrottleOverride

15. Server Object Model Example CodeUsing Microsoft.SharePoint;List<Announcement> announcements = new List<Announcement>(); SPSitesite = SPContext.GetContext(HttpContext.Current).Site; using (SPWebcurWeb = site.OpenWeb()) { SPListlstAnnouncements = curWeb.Lists[new Guid(LibraryName)]; //rest of the code }

16. LINQ to SharePoint(SPLinq)

17. LINQ to SharePointEntity based programmingStrong Types and IntellisenseTranslates LINQ queries to CAML queriesSupports List Joins and ProjectionsJoin lists on lookup field between themJoin multiple lists (A->B->C)Project any field from joined list in a query without changes in list schemaCan be used inWeb PartsEvent ReceiversSandboxed Code

LINQ to SharePoint Basicsspmetal.exeSPLinq.csSPLinq.vbspmetal/web:http://dataetch/code:SPLinq.csSharePoint Sitehttp://datatechSPLinqDataContextSPLinqDataContext dc = new SPLinqDataContext (“http://datatech”);var q=dc.Employees.Where(emp=>emp.DueDate < DateTime.Now.AddMonths(6));from o in data.Orderswhere o.Customer.City.Name == “San Francisco“select o;
