The Code Project - Arrays UNDOCUMENTED - .NET
I struggled a bit today when playing around with Array Binds using ODP.NET. A good article about arrays, ArrayLists etc. can be found at The Code Project - Arrays UNDOCUMENTED - .NET

Trivadis Tech-Event in Zurich
Joined the Trivadis Tech-Event in Zurich yesterday. It was a long friday (8 hours on the highway, 8 hours listening presentations) but is was worth it.
What we've learned?
* designing DALs (Data Access Layers) in .NET is an area where many people have many good ideas, Christoph Pletz from Trivadis is one of them. TMDA is worth a deeper look...
* After joining at least 5 presentations about Oracle HTMLDB I feel that I should play with it by myself...
* Trivadis TVDxORA is a lean XSLT based reporting framework, the people developing it can really live with all the Oracle bugs in that area...
* Indigo is a thing I should start reading about it now...

Ideas for Client Side Declarative Validations
A couple of articles are around on the net regarding how to do client side data validation prefferably in a declarative way. I like the idea and would like to dig a bit deeper into that area.
From my VCL experience I know that validations across what the VCL dataset offered (Min, Max, Nullable, data type) where not supported in VCL. I know that I would like to see something more in that area.
A good idea would be to get some support from the database itself because some of the constraints need simply to be copied to the client for client side validations. Additionally there could be server side validations (lookups etc.). Lot's of ideas here.
Maybe I'll find the time to prototype a bit in that area in summer.
2 interesting links with interesting ideas for now:
Use DataSets as Business Objects
Extending Windows Forms with a Custom Validation Component Library
