The following sections explain how to get the best use of Object Types information:

• Conventions used in the object type descriptions. Read Conventions.
• Properties that appear in many object types are described in Properties with Consistent Meanings.
• Oracle's Siebel Tools provides many object types that developers can modify. There are also internal object types that you should not modify. These are listed in Nonconfigurable Object Types.
• Several object types and properties are no longer visible in Siebel applications. These are listed in Hidden Object Types and Properties.
