Client Side Data Lookup |
Fri, Nov 16 2012 7:17 PM | Permanent Link |
John Postnikoff | I am looking at converting an application that I have in Intraweb with the use of TMS components to Web Builder. This application processes delivery orders. Each of the clients have their own shipping or address lists that are unique to them. I am wondering if I can currently somehow write and read client data that would be used to fill in Web Builder forms on the server side using Web Builder only, and somehow read the client side data or tables that have addresses unique to them, and without keeping several independent client lists on the server side.
I do have a DBISAM client-server application that does this very well, which connects to the server to process the orders once filled in in two ways. 1. It processes orders and posts each individual order. 2. Multiple orders can be entered then batch appended to the server. However for some clients they insist on only browser based applications where we cannot install software on the client side for security and other reasons. Is there a way I can read addresses and data from EDB tables that belong to each client from the client side. I am developing a pricing matrix that calculates freight prices based on a zip code to a destination. Any help or input is appreciated. On another note, it wold be nice if Elevate Software could come up with a bundled price for support, since it looks like I may be supporting all core products (DBISAM, EDB and EWB). Having to buy each one along with all the other components I have is a bit to manage at times. |

Raul Team Elevate | John,
Not sure if i understand this correctly but it can definitely be done - however you'd need to customize the server end a bit. In our case I wrote an EWB app that requires user to login and that sets up filtering rules on web services side so any future request is automatically filtered to only include records they should have access to. If you can't/don't want to do login then you could hard-code the per customer limits into EWB app or host it from a custom URL so that on startup EWB app can read it's URL and derive any SQL filters etc from there. Either scenario would involve setting up multiple instances of the EWB app though on different URLs if multiple customers access the same web server.

John Postnikoff | Yes this is what I mean. I am hoping to read a physical or memory table installed at each customer location. The problem is I can install a data file or table on the customer end. I am not able to install any application due to security reasons, and there seems no way around it unless I create some sort of filtered or un-filtered look-up unique to each customer as suggested on the server side, which I am afraid would slow performance and be difficult to manage if that was unique to each customer. I want to look at all options to see if it even can be done, and of course the best method.

However, you'd also have to turn off the same-source security restrictions in the browser that would prevent an EWB application loaded from X from accessing a dataset from Y. IOW, it's pretty much a non-starter in terms of browser security. If you have any other questions, please let me know. Tim Young Elevate Software www.elevatesoft.com |
