Working with Data Querying and manipulating data has always been a fundamental part of our jobs as programmers Data formats change, but core needs are the same

USE empl REPLACE ALL salary WITH (salary * 1.1) FOR supervises > 0 LIST ALL fname, lname, salary FOR Supervises > 0 Data Access (DBASE circa 1980s) Data querying and manipulation a core part of the programming model experience Certainly had limitations, but it sure was useful

SqlCommand cmd = new fname, lname, salary FROM Empl WHERE supervises ); 0); SqlConnection c = new SqlConnection(…); c.Open(); DataReader people = c.Execute(cmd); while (people.Read()) { string fname = (string) people[“fname”]; string lname = (string) people[“lname”]; double salary = (double) people[“salary”]; } dr.Close(); Data Access APIs (circa late 1990s/early 2000s)

Object / Relational Mapping (circa last few years) public class Employee { public string FirstName; public string LastName; public double Salaray; } IList employees = session.CreateCriteria(typeof(Employee)).Add(Expression.Gt(“supervises", 0).List(); foreach(Employee employee in employees) { string fname = employee.FirstName; string lname = employee.LastName; double salary = employee.Salary; } Map relational data to/from objects Cleaner integration of business rules and validation

But Challenges Still Remain… How to retrieve non-relational data? XML, RSS, Web Services, REST, AD, Files, etc. How to interact with plain old objects? How do you interact and query custom domain models? How to enable rich data shaping & transformations? Support flexible query composition (that is fast!) How to enable clean code in both a strongly typed and dynamic language world?

LINQ Query, Set and Transform Operations for.NET Makes querying data a core programming concept Works with all types and shapes of data Relational databases XML Plain old Objects Works with all.NET languages New VB and C# have integrated language support

New ASP.NET Data Controls

LINQ LINQ to SQL
