Form transformer -a formalism for office form manipulation-
The nested table data model (NTD) is proposed as a powerful office data modeling tool, and basic aspects of data handling in NTD are discussed. Nested tables are introduced as straightforward and uniform office data representation forms, and four form transformer operators are defined for manipulating nested tables. Then, reversibility and commutability of the form transformer operators are examined.
