~~~Add my own data type to ArcMap~~~

Discussion created by bluemaple on Mar 12, 2011
Hello, everyone!
I have some data which datatype was defined by myself store in Oracle. Now, I want to add them into ArcMap application, and save the document as *.mxd. Finally, publish this document by ArcGIS Server.

How can I do? Is the way to extend FeaturelayerClass effective??
I am working on .Net.
