There is a prototype for J2SE 1.5 new language features
The Java Developers connection has also a RSS Feed.
Redmond - June 25/26
Who else will be in Redmond in the week of June 25/26?
I'll be there!
John Lam found the same problems we did with the .NET Petshop database schema. Our article was written looking at the .NET PetShop 1.5 version. In the 2.0 version the database schema is still worse.
Am I the only dotnetweblogger who is going to attend to TechEd and JavaOne?
I'll be giving a talk on "Agile Development of Database Based Applications with Visual Studio.NET" (DEVL03).
DeKlarit will have a booth, and I'll probably be around it, so come and say hi.
I'm arriving on Monday morning so if someone is planning a bloggers' meeting please don't schedule it for Sunday night! ;)
OK. It's not Don's fault
but NewzCrawler's ;).
Thanks Brad for the heads up.
I should have been paying more attention to the 'xhtml in RSS' debate ;).
I tend to agree with Don Box in that the browser is dead. I do most of my web navigation using NewzCrawler. But if Don thinks the browser is dead is because he does not need to read his own weblog!. I hate to have to open a new IE window to read Don's posts ;).
List of Database Refactorings
Pramod Sadalage has started to capture the various database refactorings we use in evolving databases. This list will grow as Pramod steadily works through documenting the refactorings.
Mads took the red pill and it's trying Typed Datasets, and has some doubts about how to use them with Remoting. I'll share our experience with DeKlarit.
a) The Typed DataSets generated by VS.NET 2002/2003 cannot be used with Remoting because the DataTables lack some serialization stuff. You can add it by yourself doing what this article suggests, or by using another DataSet generator. There is an ADO.NET PowerToys project in GotDotNet workspaces that includes one, but I'm not sure if it solves this issue, but it's quite easy to implement. DeKlarit also generates the needed stuff.
b) With DeKlarit you can generate two projects, one with the DataSets and another with some DeKlarit-specific DataAdapters which are the ones that fill and persist the DataSets. The project with the DataSets is shared between tiers. You don't need to WriteXml/ReadXml as DataSets will serialize themselves as XML.
c) The DataAdapters are the remoted objects, and each one implements its own interface. They presentation layer code uses the interface to interact with them. Ingo explains this usage pattern here.
d) DataSets always serialize as XML even if you are using a binary formatter, and they always include the XML Schema when they serialize. I feel that there should be a way to improve this behavior, but I did not found the time to hack it.
About the database/xsd synchronization, in DeKlarit you really define a structure that generates the XSD _and_ the database schema, so you have that problem solved.
