Suppose we define the similarity and merge functions by: i. Records are similar if in all fields, or in all but one field, either both records have the same value or one has NULL. ii. Merge records by letting each field have the common value if both records agree in that field or have value NULL if the records disagree in that field. Note that NULL disagrees with any non null value. Show that these similarity and merge functions have the ICAR properties.
