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 SqlCommand( @"SELECT fname, lname, salary

FROM Empl WHERE supervises > @p0"

);

cmd.Parameters.AddWithValue("@po", 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?

LINQQuery, Set and Transform Operations for .NET

Makes querying data a core programming concept

Works with all types and shapes of dataRelational databasesXMLPlain old Objects

Works with all .NET languagesNew VB and C# have integrated language support

New ASP.NET Data Controls

<asp:ListView>
