Sample Data for the System.Identity Domain

As I’ve written about previously, I’m a big fan of the possibilities of the System.Identity domain of SQL Server Modeling Services (SSMoS). System.Identity’s Party Model implementation elegantly addresses so many scenarios that modern enterprise LOB applications face. So, I’m pretty stoked that I was able to help out in bringing some sample data for System.Identity…


System.Identity & the Repository in action at PDC

For any number of reasons I’m just now catching up on my PDC videos. Among the many that interest me as an Architect working in a very large IT shop, are a great presentation by Kim Cameron and Gert Drapers on System.Identity titled “The ‘M’-Based System.Identity Model for Accessing Directory Services”. As an IT Architect…


Fluent Interface for System.Identity – Kind Command-Query API

Part 1 of this series functioned as an introduction to the motivations for creating a fluent interface for Oslo’s System.Identity. Part 1 also covered a number of architectural and design specifications that will be followed in the shaping of the interface’s code. In this post I’ll continue the crafting of the fluent interface by exploring…


Fluent Interface for System.Identity – The Basics

<Author’s Note> A very talented Developer I know just recently gave me some very succinct feedback on my blog – “good blog…too long”. As I respect this Developer’s opinion quite highly (not to mention I always try to listen to Developers), I am going to start putting his suggestion into practice by chunking further posts…

Oslo May CTP Has Improved System.Identity!

The Oslo team released the May 2009 CTP yesterday. For those that are interested in Oslo in general, and System.Identity in particular, then effort to get the new CTP up and running is well worth it. From the perspective of System.Identity, the new Oslo CTP represents an important leap forward in terms of design and…

Implementing UML Associations and Oslo’s System.Identity

As I really don’t have much of a life I was reading an academic paper this evening by Anneke Kleppe. In the References section of the paper there were the a couple of links to some articles on properly implementing UML Associations in source code. The articles are fairly old now (they were written in…

Exploring the Party Model with Oslo’s System.Identity – Part 3

In Part 1 of this series we covered the basics of how Oslo’s System.Identity implements the Party Model and how System.Identity can be used to model real world scenarios. We continued our exploration of System.Identity in Part 2 by modeling more complex real world scenarios and illustrating how System.Identity can handle asymmetric relationships and transient…

Exploring the Party Model with Oslo’s System.Identity – Part 2

In Part 1 of this series we discussed the basics of the Party Model using Oslo’s System.Identity schema. Specifically, we discussed the System.Identity constructs for Party, Role (including the Employee and Customer specializations of Role), and TaxonomyEntry (to allow for assigning a “Kind” to Parties and Roles). We also put these System.Identity constructs to use…

Exploring the Party Model with Oslo’s System.Identity – Part 1

It occurred to me the other day that I asserted that the Party Model is a “Good Thing” without providing any proof whatsoever to back up my claim. While I would love to believe that everyone subscribes to my views and opinions because of their irrefutable wisdom, I have no illusions to the reality of…

Some Oslo Goodness – System.Identity Implements the Party Model!

There does exist some controversy right now in the blogosphere around Oslo. As I indicated previously, I’ve done a 180 on Oslo and I am now highly interested in the technology – a subject I plan to blog about soon. However, what I find interesting is that there hasn’t been a lot of writing in…
