+ 
+== Overview ==
+
+The purpose of this RFC is to enhance the !FdoClassDefinition class by adding new methods !GetIsViewBased() and !SetIsViewBased().
+
+
+== Motivation ==
+
+Existing FdoClassDefinition does not contain any information that would allow to determine a type of the base RDBMS object.
+There are cases when view-based classes should be distinguished from table-based classes to be able to handle behavioral differences:
+
+* Editing schema. View definition cannot be changed and therefore class schema cannot be changed.
+
+* Editing property values. Class data may not be editable.
+
+
+== Proposed Solution ==
+
+The following shows the proposed changes to !FdoClassDefinition:
+
+{{{
+     class FdoClassDefinition : public FdoSchemaElement
+     {
+        ...
+        public:
+            ...
+            /// \brief
+            /// Gets the value of m_IsViewBased. It is true if a class is based on view; otherwise is false.
+            /// 
+            /// \return
+            /// Returns bool
+            /// 
+                FDO_API bool GetIsViewBased();
+
+            /// \brief
+            /// Sets the value of m_IsViewBased. It is true if a class is based on view; otherwise is false.
+            /// This is an internal method that can only be called by providers. Application should not use this method.
+            /// 
+            /// \return
+            /// Returns nothing
+            /// 
+                FDO_API void SetIsViewBased( bool value );
+            ...
+        
+         private:
+            ...
+            FdoBoolean  m_isViewBased;
+            ...
+       }
+
+}}}
+== Implications ==
+
+This change will not cause any functional or performance side effects.
+
+== Test Plan ==
+
+Exisitng unit tests will be enhanced.
