1st Question in our Coaching Program

Posted by Franto on August 20th, 2008

Main data carrier in big application - E4X XML or designated data class?

Hi my friends,

I have a question about software architecture:
Imagine you have an application that load data about many persons from XML and process / utilize that data all across the application. In AS2 there will be no doubt - I will parse the XML and create ‘id’ sorted array of Person class instances. But in AS3, where sophisticated E4X XML is available I hesitate. Should I use designated data class or dispatch pieces of XML all across the application?

  • What are advantages and disadvantages of both approaches?
  • Is it even common to dispatch pieces of XML across application?
  • Is even my terminology correct? (I am not sure whatever ‘data class’ is the proper term)
  • Can you point me to some resources about modern AS3 architecture?

Thanks!
Daniel

This is first question in our Coaching Program. :) We are happy, that it has started :)

And here is answer…

Hello Daniel,

thanks for being our first paid member and for placing your first coaching question :)

Now let’s move to your questions..

The software architecture approach definitely depends on the scale of the project. None of the approach is completely wrong if it works as expected and at the same time it’s flexible, maintainable and scalable..

But in general I would not recommend to use XML data structures throughout the project code as you have described. Not speaking about the great advantage of using E4X it would still not be too scalable because when anything in your data needs to be changed then you will have to modify your code accessing XML structures at many places.

More better approach is to separate your data from your functionality and just use centralized Data Model within your application. This Data Model can just serve as a storage of all data and also represent the state of your application being implemented as a Singleton class…

Attending Singularity: Online or Offline?

Posted by Franto on August 19th, 2008

Hey, maybe everybody from RIA world know about Singularity conference. Conference details are just great:

  • What: A kick-ass web conference
  • When: Oct 24-26, 2008
  • Where: Everywhere!

Uhh, everywhere? Sure, it’s online conference. You can attend from your home, no travel fee, no hotel fee :) Nice. Today Aral has announced sessions details, and new sessions will be updated soon. But it’s not enough. It’s great that there is no extra expenses, just $99 for 3 days conference, but someone can said: But I will not meet up friends there, can not talk to people I like. But wait, Aral has another surprise for you. It’s called Local Hubs. Yes, your local Adobe User Group, or anyone who want to organize local hub for Singularity conference has possibility now. Aral has started discussion about Local Hubs, come and discuss. So there is possibility you can even travel to Singularity conference, but not over the world, but maybe in your city or somewhere near your town :)

We will be there :) Do not know if we will attending Singularity conference online or we will have chance to attend it from some Local Hub in Slovakia.

  2. 360Flex Europe - Day 1

So we have attended the Day 1 of 360Flex Europe Conference here in Milan.

This day was completely free thanks to the sponsors that the organizers were able to get in touch with.
It was really nice to meet some folks from the Adobe Team (especially Enrique Duvós and Sumi Lim) and also new people from the European Flex community.

We have seen some interesting presentations:

  • Adobe AIR: Cross-Scripting Techniques by Xavi Beumala
    Xavi was talking about using some interesting techniques to use HTML component in AIR that enables to expose DOM API of underlying WebKit HTML engine and use it for manipulation of HTML rendering in AIR applications.
  • Better Flex and AIR Applications Using AJAX by Marco Casario
    Marco was talking about bridging the Flex vs AJAX and use them together to take the benefit of both of them. The main idea was that the both of them are just complementary technologies and not the competitors.
  • Flex Bitmap Effects! by Luca Mezzalira
    Luca has shown some interesting bitmap data manipulations and effects in Flex applications with realtime webcam images using the BitmapData API of the Flash Player. He also presented the usage of some bitmap filters and approaches for motion detection.
  • Video Streaming with Flex and Flash Media Server by Eros Marcon
    Eros talked about video streaming in Flex using Flash Media Server. He walked through some examples of creating simple video player and shown techniques on using the incoming stream data to enhance the usability and user experience.

After the presentations we took part at the Birds of a Feather session sponsored by one of the partners where we enjoyed a couple of talks with people from the Flex community together with some refreshments and glasses of wine ;)

It was really a pleasant day today and we really enjoyed it. You can check out some photos from today’s Day 1 of the conference in our Events page.

Just stay tuned for more news from 360Flex Europe Conference in Milan.
