About Changing the Database Schema in a Development Environment
The first step in deploying Siebel database schema changes is to make the schema changes in a development environment, using Siebel Tools. For information about this step, see Configuring Siebel Business Applications.
Keep track of whether your changes include creation or modification of views or applets. This information will affect later steps in the deployment.
Test the changes in the development environment before proceeding to the next part of the process. For links to other steps in this process, see Process of Updating a Siebel Database Schema.
