web application to display sensor values on a map

Question

Hello,

I am a developer with j2ee background and do not know what approach to take to develop a web application where we want to query data in an Oracle DB (sensor measured values) and then to display appropriate graphics for the selected sensor on a map. We want to use ArcGIS online if that will help and we have bought ArcGIS server and desktop. So basically when the user selects a sensor location on the map he/she should see a graphic (eventually in a pop-up but not mandatory) with the last n measurements of that sensor for a specific chemical property (such as pH or Turbidity, etc). These values are stored in an Oracle DB.
What is the most straightforward approach for this?
Please provide detailed instructions (step by step).

Thanks is advance 
Best regards,
Sorin

Hi Mark,

Thank you for your response

You could configure your own application via ArcGIS Online.

Or you could consider one of the configurable viewer applications which allow you to build and deploy applications which in the background use the Flex or Silverlight.  For a lot of simple applications  this is a really quick way of getting an application up and running.

Good luck with your web application!

The configurable applications from ArcGIS online did not offer the capability to connect to a RDBMS like Oracle to query data and render them in a popup on a ArcGIS map.
For the same reasons enumerated above the viewer applications did not offer what we were searching for so I assume that only writting our applications with one of the ESRI's web API reamins.

Hi

Having looked at what you are trying to achieve, I believe it will be really easy.  The title of your post however suggests that you are wanting to write an application which resides in an internet browser.  This forum is about writing native applications so I'll try to point you in the right direction.

You have a few options, you can either write your own browser application using one of the web APIs available from ESRI:

- Flex API https://developers.arcgis.com/en/flex/ for browsers which support Flash based applications
 - JavaScript API https://developers.arcgis.com/en/javascript/ for wider browser support
 - Silverlight API https://developers.arcgis.com/en/silverlight/ for a non Java alternative

You could configure your own application via ArcGIS Online.

Or you could consider one of the configurable viewer applications which allow you to build and deploy applications which in the background use the Flex or Silverlight.  For a lot of simple applications  this is a really quick way of getting an application up and running.

Good luck with your web application!
