ArcSDE & Geodatabase Interaction

[MartinKunert]

Hi,

I am creating a web application using ArcGIS Viewer for Flex.

My web application will include drawing a route on a map. My requirement is to capture the details from the Client and update the captured information into a Geodatabase[PostgreSQL].

I am exploring to use ArcSDE to achieve Geodatabase interaction.

Is my approach correct? Is there any examples/samples capturing the above work flow.

Hi Martin,

Yes, what you are proposing is possible. You would simply publish a map document that contains the feature class (in your PostgreSQL geodatabase) you want to add your route onto, as a map service with the feature service property enabled. Make sure that you've defined a template for that feature class. Then simply reference the feature service in the Edit Widget of the ArcGIS Viewer for Flex.

Some resources:

• Editing in Web applications


• About feature templates


• Using feature services


• Edit Widget in the ArcGIS Viewer for Flex

Hope this helps,

Hello Derek,

Thanks for your answer.

I am able to get your explanation.

But I am still wondering how it works out in the larger picture. When ArcObjects comes into picture? What role ArcSDE plays here? How does ArcGIS server supports the above work flow?

Thanks..

Hi Martin,

When ArcObjects comes into picture?

A1. ArcObjects is the developer technology that was used to develop ArcGIS Desktop (the map authoring application), the geodatabase data model, and some parts of ArcGIS Server.

What role ArcSDE plays here?

A2. ArcSDE technology is used behind-the-scenes to set-up and enable the ArcSDE geodatabase on the PostgreSQL DBMS platform. The data model where you store your GIS data.

How does ArcGIS server supports the above work flow?

A3. ArcGIS Server is the software that enables you to publish and share your GIS resources onto the internet/intranet. In this case, your map becomes a map service with an associated feature service.

Please review the help documentation for more information.
Hope this helps,

Hello Derek,

I am trying to create a feature class.I have ArcCatalog installed and created a database connection for postgreSQL.I have created a feature dataset and a feature class with line features.

I am trying to understand how to create a feature template and how should I refer it to a map, so that I can create a feature service and use it in my web clients.Do I need ArcMap to refer a map and enable the feature class?

Regards,
Vimal

Hi there,

... I am trying to understand how to create a feature template and how should I refer it to a map, so that I can create a feature service and use it in my web clients. Do I need ArcMap to refer a map and enable the feature class?

Yes, you will need ArcMap to set-up and enable feature templates on your editable data layers in your map document. Then publish your map with the feature service property enabled.

Please review the documentation that I referenced in my previous posts.

Hope this helps,
