  • Blog Post: Stop, Drop, and Roll

    A couple of weeks ago, I made a post that I thought some sort of client side data structure, which was designed to store projections of a domain model instances (both in memory and persisted in a data store), was a necessary part of any O/R framework. My conjecture was that this was required due to the...
  • Blog Post: Nix the DataSet??????

    Some interesting comments from my entry on new DataSet features… Please nix the DataSet from the framework entirely and re-focus on the domain-oriented data access work you were doing prior to Tech-Ed 04. If that's not possible, please have the Visual Studio team desist from distracting .NET culture...
  • Blog Post: O/R redux

    One of the big conversations that has been going on for some time in the Java world is how prescriptive container frameworks such as EJB and Spring should be. It is fairly well known, that for O/R mapping frameworks the same conversation exists since O/R persistence is really just one (albeit complicated...
  • Blog Post: One crazy Italian

    Luca Bolognese, one crazy Italian, now has a blog … and he is even writing it himself. Luca was Mr. ObjectSpaces back in the day and is now working with the C# team on the sequence operator work.
  • Blog Post: Comment on a good comment

    Got a very observant comment on my ObjectSpaces and WinFS Part 2 entry: My big scare is that merging ObjectSpaces and WinFS will restrict me from using OS as the persistence layer in places where the customer doesn't have and won't upgrade to the latest windows platform or even the latest SP... in these...
  • Blog Post: The Good, the Bad and the Ugly

    I will be posting more about the changes to the ObjectSpaces release plans in the near future- but in the mean time, I wanted to make sure everyone was aware of that we are willing to listen to any and all feedback about the changes. The following lists all the avenues to do so: 1. Email the feedback...
  • Blog Post: Ramblings about POCO*, transparency and delayed load.

    As someone pointed out, I have been referring to ObjectSpaces as supporting true POCO – which is technically incorrect. ObjectSpaces does prescribe the usage of ObjectHolder and ObjectList for delayed load cases (more of the merits of delayed loading down below). However, beyond that – there...
  • Blog Post: Orthogonal to Orthogonal

    I think Ralf post about “ Should object persistence really be thought of as orthogonal functionality?” is orthogonal to the real problem that ObjectSpaces is trying to solve. It seems his overall point is that by allowing any domain objects to be persisted to a relational store will lead...
  • Blog Post: O/R BOF talk

    Scott Bellware has proposed a Object/ Relational birds-of-a-feather talk for TechEd 2004. If you are interested, please make sure you vote for the topic. Based on the strong showing for the same topic at PDC, this talk should be quite lively.
  • Blog Post: Talk ideas and dinner?

    I am giving a talk at TechEd 2004 which we have never given before called: DAT380 Building Applications with ADO.NET ObjectSpaces Friday, May 28 9:00 AM- 10:15 AM Speaker(s): Andrew Conrad Track(s): Data Management, Developer Tools and Technologies Traditionally, object oriented business...
  • Blog Post: Data Access Panel at TechEd 2004

    I will be hosting a Data Access discussion panel at TechEd 2004: DATPNL Data Access Round Table Thursday, May 27 11:45 AM- 12:30 PM The following people will be participating in the panel discussion: Mark Fussell – Lead Program Manager for System.Xml and English soccer apologist...
  • Blog Post: POCO

    Encarta definition - a little or slightly (used in musical directions) ObjectSpaces definition - Plain Old CLR Objects
  • Blog Post: Dino on ObjectSpaces

    Dino Esposito has a nice introduction to ObjectSpaces on MSDN . Not particularly in depth, but is an excellent introduction to the API and mapping syntax.
  • Blog Post: Bare Bones Sql versus OR (?)

    I have to say I disagree with Ingo’s comments about preferring “ bare bones Sql ” over O/R mapping technology. IMO, the two topics are orthogonal. Data Access is all about solving high level use cases. There are no rules out there that say one must give up the explicit, low level...
  • Blog Post: 2004

    I started working on the outline for a book I am planning to write about ObjectSpaces. My goal was to get it started before 2004, so there you go - well ahead of schedule. Please don't tell Dare though, I am suppose to be finishing up a long over due ExtremeXml column for him today. In fact, it is...
  • Blog Post: Englishman in Redmond

    Mark Fussell, a semi crazy Englishman I work with here at Microsoft, has co-authored a good introductory book about the what's new with ADO.net and SqlXml in Whidbey. I reviewed the latter content and found it quite detailed and well written. The book also includes a short section on ObjectSpaces...
  • Blog Post: Don Box interview

    Interesting interview of Don Box by Mary Jo Foley (of Microsoft Watch fame). I think his comments on OO and the SOA world are right on.
  • Blog Post: ObjectSpaces in an SOA world

    There have been several internal email threads here at Microsoft about how ObjectSpaces will fit into the world of SOA. Below I have included my internal reply to one such post on the subject. Note - my reply is not intended to be a manifesto on the subject, but more a conversation starter. Posted...
  • Blog Post: the million dollar question

    Paul Wilson  has asked me what seems to be by far the most common question about ObjectSpaces: “Will it support other databases besides Sql Server... i.e Oracle, Access, etc?” For V1 of ObjectSpaces, which will ship as part of the Whidbey release of Visual Studio, only Sql Server 2000...
  • Blog Post: Luca's PDC presentation

    Luca's PDC presentation on ObjectSpaces is now available.  So is the sample code .  
  • Blog Post: PDC 2003 samples and mapper utility posted

    The bits are now available for download via the GotDotNet samples page.  This is the same samples and mapping utility that we distributed at PDC 2003 on the ADO.net samples CD. We are still working on a more permanent home, probably the ObjectSpaces' MSDN web site - once it is...
  • Blog Post: ObjectSpaces' performance requirements

      From a comment on my “ObjectSpaces Myths” post:   “ However it's NOT a myth that ObjectSpaces is spec'ed to be 40% slower than DataSets, correct?”   The comparison is actually not that simple.   There are two basic reading from the...
  • Blog Post: ObjectSpaces Myths

    From the Post-PDC 2003, feedback there seems to be a number of fallacies circulating about ObjectSpaces.   I have attempted to answer of few of those below: ObjectSpaces is a thin layer over ADO.net ObjectSpaces utilizes the SqlClient support of ADO.net to query and persist...
