Database developer's gentle view on D.
Not that you really need it.
Things move forward. Phobos becomes more and more reliable and usable, 
It seems that the accepting "Foreign modules/Fixes situation" is better 
than ever.  So it looks like things went into the right direction.... 
unfortunately not for me.

Let  me tell you in a second or two about my world.
Creating huge database based multinational applications   (likewise 
multinational/lingual Accounting - Order Sys.)

As said, I have to create Database applications,  consuming SOAP 
respective REST Services. Targets are Desktop(WIN only), WEB and Smart 
Devices. All of them have to interop.

So why not using D ? (Which I would like to do)

DB Support..
   Not yet available. In case that Steve Teale (and he did a dammed 
good Job, as well as Piotr) will add std.database this will not change 
the situation significantly. 'Cause std.database will contain just 
rudimentary DB support..  A Database independent, ORM based library 
module is not even matter of discussion. That's a  pity.

GUI..
    Well for us Windoze is the only interesting Desktop platform.
A _reasonable_ GUI is not available yet.(D-GUI looks pretty good,though)
WEB Development is for sure doable in D, reusable Frameworks are 
nevertheless AFAIK not available.

Smart Device Development..
   (Win 7 mobile/ Android/ IOS ) GDC for rescue ? On Android D To Java ?

Consuming SOAP/REST..
 ATM std.XML is not really perfect. So going a step ahead and asking 
for parsing WSDL files to generate appropriate D code would not make too 
much sense.
Further : Some Services require Certificate authentication. Another  No 
Go. No Crypto lib.

Don't get me wrong, I like D!  Otherwise I would not have followed  D 
for meanwhile 5-6 years.

Without having an DB-Object Relational Mapper, Crypt/Decrypt- extended 
XML support, PDF creation, Reporting, and XML related tools and (mucho 
importante) localization support,  D is not an option for us  --at the 
moment.

 So ... Being a bit enthusiastic about D's progress ? Sure!
 Leaving the planet, went to outer space with a  D Type _2_ Rocket made 
by BOING engineer W.B. ?    Risky ;)

A+

That would be nice, indeed.

What is D-GUI, gtkD or DWT?

dgui:

GUI library for Windows.  Pretty easy to use.

-

gtkD and dwt2 are cross-platform GUI libraries for D.

Thank you, but not interesting for us looking for multi-platform
library.

Bjoern,

Even being retired does not mean there's nothing else to do but D library 
components. I didn't get back to you yet because I'm busy making 
furniture for our expanding little enterprise here, and because of the 
holidays, and because I need to lose a few kilos off the belly that 
magically appeared while I was doing nothing but sit in front of a 
keyboard.

Also I'd say for rudimentary I'd want to say basic. There's a slight 
difference.

I'll be back.

Steve

But don't put the database stuff

What kind of features did you have in mind for this?

Hi Adam,
first of all: A happy and successful new year to you!
To answer your question  :
An SaaS application living in a Cloud-Space, preferred atm is Amazon EC. 
The database Back-End will be (most probably PostGreSQL)
WHY PostGres ? Callback notifications/ Server-side events ... not 
available in MySQL. (which you prefer in your framework)
Another point is DB replication, partial DB replication. #

The challenge for us is SaaS user management.
Due to the fact that we are supporting small companies(1-5 users) as 
well as huge,international acting companies the Saas Software has to scale.
I.E. From : "I would give your Software a try. We need just the basic 
package" ... to "We want it all (and more); We are looking for a long 
term contract" .
In detail this means we have customers who wish to rent just PARTs OF 
OUR SOFTWARE for a month, others would like to rent our Software for a 
year, including all features.

SOAP/REST  is (in our case) needed to f.i. obtain prices. (https 
tunneling seems to be good enough (tm) )The other need for SOAP/REST (I 
am not sure if should go this way) is to access the SaaS application to 
receive certain informations/to add an potential clients, reuests, what 
the heck. ) In this case we have to establish a WSDL/REST - maybe oData 
Service.  (I would  prefer REST)

---Still have a hangover from new years day, so that's it 4 the moment.

Indeed, I had your library in mind while talking about D for the WEB.

Hi Steve,
first of all: A happy and successful new year to you!

What makes me a bit nervous is the use of structures in your source.
In case that your goal is to establish a D database access standard, 
client and server wise, Interfaces are the way to go.

Well, isn't  the right of the youth to be impatient :) (I am just 50)

So I am waiting for your feedback regarding the link I've send you. In 
my (in this case not so humble opinion) following this Design would make 
much sense.
Kind regards, Bjoern

... and should be named Forms4D

I definitely like this library. Pretty straight OOP, Each DOTNET Forms 
developer will immediately  feel at home. New liberal license. Just cool!
