Real world use

[Mike]

I would like to hear about some real world applications written with ewd.

Hi Mike,

For one of my customers, I've created an EWD application to show information of a Caché database. His agents are using the app to consult real-time data over the internet. This was done with "pure" EWD without any components (as ExtJs). Superfast even on a simple server and simple standard internet connection.

I'm currently developing an application with EWD in combination of the Sencha ExtJs framework. I like a lot the Ajax way of working of EWD and the way I can keep business logic seperate from the interface. All data lookup, validation, creation, preparation, ... can be done in my Caché classes. In the EWD pages : only GUI issues.

Regards,
Marc

Thanks Marc. I have had so much trouble installing WLD on my new
server, that I have given up and am going to re-write my application
in EWD. I hope it doesn't take too long to get up to speed... :)

Mike,

I have several applications running in a production healthcare setting. These applications range from a view only daily schedule for outpatient providers to a real-time patient dashboard for each inpatient ward. On the IT side there is a system management dashboard for VISTA on GT.M. These applications are using the full suite of Rob's work, EWD, Sencha Touch, and ExtJs.

Mike:

You might start with Quest Diagnostic's entire patient-facing web system, Care360. It is written totally in EWD. I don't think they have taken advantage of the ExtJS framework yet as the system has been growing for years from its roots in WebLink Developer. However, the vast improvements in the operational and design aspects of EWD make them even more responsive to changing customer needs than they were before. I have a number of apps out there in various stages of completion. If you email me directly, I can show you a Powerpoint of a system we built that is running behind a corporate firewall. I would suggest that it could not have been built without ExtJS (or a framework of similar power) and the arcane code required for by ExtJS could not have been built (by me, anyway) without the shortcuts and implementation fixes provided by EWD.

Indeed, I am struggling now with a corporate mandate to rebuild the prototype system in Zen/CSP...ugly. Attempting to use Zen to model things that ExtJS makes trivial exposes some of the huge underlying flaws in the Zen paradigm. Of course, the EWD pages compile into CSP pages directly so you only have to deal with a few odd things about CSP...but so does everyone who builds a CSP app.

Some of problems with Zen include the fact that it still uses html tables to control element positioning. Essentially, Zen is still page oriented (instead of page fragments like EWD)...The notion of building a container page and loading various elements into data panes and constantly morphing the UI..is only marginally possible in Zen. 

An aside: my peers at work are brilliant Cache/Mumps programmers and masters of older tools like FDBMS and MSQL. The are a bit farther behind the curve with web interfaces. My lead developer discovered the classic ZenGarden website (http://www.csszengarden.com/). This is a gallery of interface designs that take the same informational elements and totally reformat and style it using positional CSS stylesheets...as you might guess, this was very interesting. However, when I told him that most of the techniques described cannot be used with Zen...not so happy! 

EWD/ExtJS makes you brilliant.

Hi Mike,

 

Sorry for coming to this conversation late, but as John Bertoglio pointed out Quest Diagnostics have a huge application running on EWD and weblink. Take a look at this presentation from AjaxWorld 2008:

 

http://www.slideshare.net/george.james/missioncritical-ajaxmaking-test-ordering-easier-and-faster-at-quest-diagnostics

 

EzOrder is still running very successfully and the numbers are much larger than the 150 million tests per year quoted in the slides.

We are now rolling out a new Order Entry solution alongside EzOrder, which is also EWD-based.

Our hospital clinical portal is written in EWD, ExtJS and Caché, sitting on top of the in-house PAS written in Caché.  It is used by up to 1000 discrete users per day with upwards of 500 concurrent users at peak times.

Hi Mike,

I have been looking at several different options for implementing modern applications with a nice GUI. Some of the aspects I've been considering leads me to only one option: applications running in a browser.

When you write an application these days, there's one key thing you have to keep in mind: it has to run on totally different devices with a lot of different browser(s) and versions. Supporting an application running natively on Windows, Mac, iPhone, iPad, Android, ... is an nearly impossible task in terms of maintenance.

Using the EWD/ExtJS/Sencha Touch combination is a real big winner because it simplifies the design and programming of your application a lot and let you concentrate on your application instead of having to deal e.g. with browser formatting details and HTML/CSS quirks of every browser.

In my case, I'm using EWD in several flavours: some applications are just using EWD to generate just plain HTML pages very efficiently, another is being implemented with Sencha Touch (a customer facing application with a touch screen), and the biggest one I'm currently busy with is a desktop application with ExtJS replacing our old terminal based ERP system.

I want to be able to run these application on different kinds of devices efficiently, running the application on top of Caché with real-time data without having to worry about browser versions, different operating systems and more of these "nice" system details.

I've been implementing a lot of different applications in the past in quite different environments - but to be honest, the way I'm working now with EWD in different flavors is without any doubt the most efficient way for me.

Hi All,

I am new to this group.  I am currently working with a Federal customer considering using EWD.js.  Are there any other customers using EWD.js that can provide feedback?  Also, what have been their experience around development, testing, performance and operations?  Any information is appreciated.
