EWB doesn't connect to a database - you make a request to a Web Service you build.  Your Web Service can deliver from any database.

Down the road if Tim "builds" a Web Service into EDB - he can do that, it is his DB.  But he cannot build a Web Service into another DB.

Hey - maybe I'll build a generic Web Service DB - I use UniDac from Devart for other DB's and Devart now support EBD!!

Look at SuperObject for your JSON needs in Delphi - is is at:

http://www.progdigy.com/?page_id=6

http://code.google.com/p/superobject/

You have to do a bit of looking around for examples / samples on how to use SuperObject.

I attach a form and small unit that can take a TDataset and convert to JSON with SuperObject.  (Was using DBISAM).

procedure TForm1.Button1Click(Sender: TObject);
var
json:TTableJSon;
obj:ISuperObject;
s:string;
begin     

 S := json.JSonFromDataSet(DBISAMTable1);   //  Take Table

 obj := SO(s);
 memo1.lines.text := obj.AsJSon(true,true);   // Output as JSON

end;


At this point your Web Service would send the JSON data to your EWB Application to consume.

Thanks for all the info and sorry for all the stupid questions.  It just that I have never created a webservice
in Delphi but would like to learn.

How do you deploy a webservice created in Delphi onto the webserver?

>>How do you deploy a webservice created in Delphi onto the webserver?


See Binaries - Example - Delphi Web Server + EWB

It is a Web Server - it provides a service - the service is "time" when it is asked via "/time"

I used Port 81 since I have a real webserver running on port 80 (which is www default).

How to Deploy?   -  Well if you actually write your own web server as in this example, then that is what you deploy.  You write this as a Windows Service and deploy it that way.

One thing, your server domain hosting your EWB App has to host the Service or else it will not work - this is a restriction "domain boundaries" imposed on us all.

Godfrey,

<< Will the database connectivity be limited to your products or will we be
able to connect to others.  The hosting service I subscribe to only has
MySql and MS SQL >>

You'll be able to connect to any database on the back-end.  In the IDE,
initially there will be ADO/ODBC, DBISAM, and ElevateDB support for easily
creating datasets at design-time.  The general idea is that you'll
eventually be able to create basic data-aware apps for the browser with a
few clicks and some dragging and dropping.

This sounds great, it would be a winner.
