"Oslo"

Imagine you've shipped v1 of your database applications against a schema created from "M". Now, you're about to ship the v2 of your database, but what about the v1 clients? Are the tables and views exposed from your database backward compatible or are you going to break those existing clients? How do you even find out?

Well, wonder no more! Telerik has shipped the alpha of their "Oslo" comparison tool, which can compare v1 of your "M" source code against v2 to see what's changed and whether that's going to break your v1 clients. And as if that weren't enough, they're working on another version of the tool that will create scripts so that you can migrate your v1 data to v2 after you're satisfied that your v1 clients will continue to work.

And the best part? It's all free! Download yours today.

Stephen Forte and Mehfuz (who, like Prince and Cher, needs no last name), have built LINQ to "M", which means that if you've got "M" source code like this (shown in a C# string variable for loading convenience):

string MGraphCode =
  @"{{Name=""Stephen Forte"", Age=37}, ... }";

and a C# type like this:

public class Person {
  public string Name { get; set; }
  public int Age { get; set; }
}

then you can load the "M" source and run LINQ queries against it:

var persons =
  QueryContext.Instance.Load<Person>(MGraphCode);
var result =
  from person in persons
  where person.Age == 37 &&
    person.Name == "Stephen Forte"
  orderby person.Name ascending
  select person;

Enjoy!
