The model attribute name consists of two parts: a column name, and a subcolumn name.
column_name[.subcolumn_name]
The column_name component is the name of the data attribute. It is present in all model attribute names. Nested attributes and text attributes also have a subcolumn_name component as shown in Example 3-2.
