Would I be jumping the gun to announce to my clients that I can now give them an option for developing web applications that can use their DBISAM based programs as a data source?

I am afraid that if I do this and EWB is still up in the air, I will be forced to use other means to develop the web applications if clients want them in the near future.

Frederick,

Following is just my opinion - i don't have any other info than what's
been published on elevatesoft website and these forums.

This is the kind of question only you can answer based on evaluating EWB
and seeing if it meets Your's and your clients requirements.

I think the only thing about EWB being "in the air" is the actual
release date - i'm very confident Tim is committed to the product and in
its current state it's already very useable. However, it's also a
version 1 product so there will be lot more capability along the way as
both EWB and EDB mature.

EWB early preview resulted in number of us asking for additional
features so rather than releasing a less useful ver 1.0 and then adding
features later Tim decided to delay the release until it's ready which
should be soon but no ETA ye AFAIK.

Another thing to mention is that there is no specific support for DBISAM
in EWB. EWB is strictly for client side Javascript so you will need to
create some kind of back-end web service to access data in DBISAM (or
any other database).

Tim has mentioned EDB will gain some more native type access (built-in
web server + json) but that's in the next EDB so for now even for EDB
you'd need to roll some kind of a back-end yourself.

Raul,

Thanks for your message.

I am only thinking of using DBISAM as the database for internally hosted applications. For externally hosted sites, neither DBISAM nor EDB would be a good fit because these sites do not allow these database servers to be loaded. I can only look at using MySQL or MSSQL.

If not for the touted drag-and-drop design capabilities and Object Pascal language support of EWB, I would not have waited so long.

Hi Frederick

I'm already using it to build a reasonably sophisticated public-facing
application - what's there in EWB even now is very impressive. I'm
aiming to go live with a beta in about 2-3 weeks, and along the way I've
built myself a flexible framework that I'll be using in other apps going
forward.

As pointed out by Raul, how you extract the data from the database for
use in an EWB app isn't part of the framework - it's client-side only.

Cheers, Bob

Thanks for the feedback.

Would you say that EWB in its current beta form, is ready for prime time and there are no show-stoppers to say, build an order entry system for the web? I would venture to say that until the final product is ready, database connectivity will be difficult to use unless a developer is technically savvy.

I'm not really in a position to say that - all I can say is that I'm
personally confident enough in the product to go ahead with a release.

Database connectivity is a separate issue and will be so even in the
final release. EWB isn't intended to act as a db access layer - it
creates client-side code. The data comes across as JSON format but how
you create that package on the server-side is up to you. I've seen
mention of PHP here on the forums but it's not something I've used. I
use RemObjects for data access, but there are plenty of other frameworks.

Cheers, Bob

Sure, EWB works fine in this regard.  The sample application that I posted
is a data-aware EWB application that uses DBISAM tables:

http://www.elevatesoft.com/cdcollector/cdcollector.html

And I posted the web server used here:

http://www.elevatesoft.com/forums?action=view&category=ewb&id=ewb_demos&msg=26&page=1

The IDE and framework are done, and they include complete dataset
functionality.  The big missing piece, though, is the back-end, which you
still have to handle yourself for dealing with the JSON that goes into a
TDataSet, as well as the JSON that comes over from transaction commits.  See
the web server for examples of how this JSON is generated.

As Raul indicated, EDB will be the first of the two database engine products
to include back-end web server functionality for working seamlessly with EWB
applications, followed by DBISAM, if time permits.

Based on this, it looks like EWB is good to go! With documentation on how to handle the JSON part for database access, this should get the developer delivering usable applications.

Now, if you could work out the pricing for existing customers, that will be nice. Smile

I know this but I am not sure if there is only one version of EWB since the order link for EWB points to a "standard" version at $299. I am using DBISAM Client Server with source code and I was expecting there will be a different version of EWB (maybe Enterprise, Advanced?) for these customers.

Unless...there is only one version of EWB or the current pre-order allows the purchaser to receive the highest level of EWB later at no additional cost.
