Data Access blog : PDC-2005

Quick update re: Data Access blog.

We're putting this blog (Data Access blog) into suspended animation. That doesn't mean we will stop blogging about ADO.NET and data access stuff, or that we'll take down published posts or comments here - it's just means we'll carry on blogging about ADO.NET (current and future releases including info on ADO.NET Entity Framework, EDM, LINQ to Entities, etc) at our shiny new ADO.NET blog and blog about other data access technology related posts at our other team blogs (see below).

If you are subscribed to this blog's feed (there are quite a few of you!), please update you reader / aggregator so it points to the new ADO.NET blog's RSS feed or Atom feed. We can't automagically redirect you, so sorry for the hassle here.

Comments on this blogs.msdn/com/dataaccess blog will be closed, but we have re-published this blog's June and July posts over to the new blog, so you can comment there if you like.

In case you are wondering, here's run down of the various blogs run by the Data Programmability teams:

The Data Programmability team blog (more about data access in general, rather than about a specific technology)
SQL Protocols team blog (discussions related to Microsoft's SQL Server Protocols - Netlibs, TDS and (new for SQL 2005) SOAP. Topics include connections and SQL connectivity)
XML team blog (covers XQuery, XPath, SQLXML, XML Editor, XSLT, XSD, XLinq (LINQ to XML) and more XML goodness)
ADO.NET team blog (ADO.NET and System.Data namepace, posts on current and future releases including info on ADO.NET Entity Framework, EDM, LINQ to Entities, etc)

Also, check out the MSDN Data Access and MSDN XML Developer Centers.

Hope to see you there!

PDC 05 demos - Query Processing over DataSet, Fast Uploads, Caching

DataWorksBlog — Tue, 10 Jan 2006 01:38:00 GMT

First of all I’ll have to apologize because it took me several months to put this code out here. Right after PDC we were so busy that I didn’t have the chance before to sit down, clean-up the code a little bit, add a bunch of comments and write a README file.

Finally, here are the samples for the PDC session DAT408 - "ADO.NET 2.0: Advanced Data Access Patterns". The demos include:
- A small sample query processor that allows you to run queries (with projection, filter and joins) over the DataSet
- An implementation of a technique for really fast change processing against a database server
- A demonstration of a caching scheme that uses SqlDependency and DataSet for granular cache loading and expiration

You can also see the actual talk with me speaking here, you can download the slide deck here, and the whole talk for offline viewing here.

Enjoy! (and sorry again for the delay :)

PDC05 is next week!

DataWorksBlog — Thu, 08 Sep 2005 20:38:00 GMT

The Microsoft Professional Developers Conference will happen next week in Los Angeles. We’re all really exited about this and we’ve been working on content and demos for our talks, as well as cleaning up some of our prototypes for the future generation of .NET technology to bring them to a show-able state :)

Here comes my plug: I’ll be doing a session on ADO.NET titled “ADO.NET 2.0: Advanced Data Access Patterns”. My goal is to touch on tough topics that require non-trivial handling of ADO.NET and related technologies to get right in high-end scenarios. I’ll focus on three main areas:

Fast change processing: Getting data our of the server fast is relatively easy, but how about sending changes back? I’ll show techniques that will help you process large amounts of changes not 10% or 20% faster, but 2 to 5 *times* faster.

Middle-tier caching: If you have a lot of data around, you may not want to hit your database server every time you need to serve a bit of it. In this section I’ll discuss and show how to do caching with the DataSet and use SqlDependency to expire the cache with controlled granularity instead of all-or-nothing.

Query over DataSet: Now, if your cache is really large, you may want to query your data rather than walk through data-structures. In this last part I’ll discuss how to implement a small query processor that runs over the DataSet and can do projections, filters, joins, etc. And you get the code!

Also, I’ll be doing some demos in David Campbell’s talk about data futures. If you want to know more about the things we’ll be doing in future versions, you can’t miss this one :)

Finally, several folks from the ADO.NET team including myself will be there hanging out in the Data and Systems Track Lounge and in the Ask the Experts event; so come by and say hi!

See you in L.A.
