Autumn Seminar 2009
Held at the Robinson Centre in Wyboston, where EDUC 2004 took place, and supported by Data Access Europe, the audience was treated to an intensive series of presentations with a largely Web Development theme.
Bernard Hill, Asckeys Commercial Director, set the scene with a Back to the Future observation that we seem to have come full circle; from centralised UNIX, DEC, CDOS and Turbodos servers through distributed fat client networked PCs and now back to a centralised model, but one that is potentially on a much wider, even global, basis than could have been be realised back in the 1980s. If nothing else we now have the bandwidth to support such global ambitions.
Eddy Kleinjan (Data Access Europes Technical Director) gave a very informative presentation combining practical tips on Web Application Development/Software as a Service, and how you might go about getting a presence in the world of "Cloud Computing". Later, Eddy presented an update on the VDF AJAX Framework, an impressive and extremely beneficial method for creating interactive web applications such as you will not yet see in any great numbers as yet. We in the VDF community can be ahead of the curve here!
Sandwiched between these presentations, Vincent Oorsprong, who runs Training and the Help Desk at DAE, ran through the features of HelpDesk Express, built with the VDF AJAX Framework.With properly organised software support an increasing requirement for serious application development, HelpDesk Express may well be on your shopping list next year.
Martin Pincott (Technical Director, Asckey Data Services) then highlighted some of the newer features that have been built into the Visual DataFlex development studio.
After lunch, presentations on Dynamic AI, the soon to be released Data Access Visual Report Writer, and the new VPE library for Visual DataFlex showed how much choice we have now in choosing reporting methods for specific needs. From completely open end user reporting with Dynamic AI, to "programmer only" pixel perfect reporting, we have a very comprehensive reporting tool set available.
John Tuohy, Data Access Worldwides "VDF Architect" rounded off an information packed day with a live webinar covering current and future VDF development.
With all these "new directions", what do our developers think? We have had two comments that are significant
From Ian Smith, one of our VDF SIG Codejock package contributors
It was a very good this is Ajax version 2 and this is all you need to do to start using it. As someone who does not need Ajax / Web at the moment it did exactly what I wanted which was to bring me up to speed with the current changes.
The seminar did not really need any understanding of WebApp. If you want to extend the Ajax framework you will need some JS / DOM training. If you just want to make good use of the framework as supplied then a course that focuses on the VDF Ajax library and Web Business Objects would be good.
We hope to be doing just that in the New Year!
Dynamic AI and VDF WebApp Server
From Dave McKane, Datos
I have to say both Colin and I were very impressed with what we learnt last week and have now began to move towards implementation of both Dynamic AI and WebApp into our application.
During the next three months we will be converting the ledgers from our character mode software (COMiT) into our windows package, Season and we will be converting from DataFlex into Microsoft SQL before the end of December..
We will be developing our ledgers and incorporating Dynamic AI into the package at the same time, our logic is to develop the ledgers with a file structure that will allow us to easily use Dynamic AI, that means we have an opportunity to get things right at the beginning.
We plan to launch the ledgers and Dynamic AI at the same time to our customer base etc - this is the final push in an almost 3 year development program..
It was fortuitous that you had your seminar at this time. We also plan to write a Sales Rep CRM module using VDF WebApp in the new year. We already have a solution for this written with Momote (an interface for PDAs), but there is much more opportunity for a package on the Web and again using Dynamic AI and Ajax.

Many developers have expressed a wish to not be tie to just one solution for reporting. We now have three solutions for reporting other than Crystal reports - Dynamic AI, Visual Report Writer, and VPE
