Query: Abstracting spreadsheet data flow through hypergraph redrawing   We believe the error prone nature of traditional spreadsheets is due to their
low level of abstraction. End user programmers are forced to construct their
data models from low level cells which we define as "a data container or
manipulator linked by user-intent to model their world and positioned to
reflect its structure". Spreadsheet cells are limited in what they may contain
(scalar values) and the links between them are inherently hidden. This paper
proposes a method of raising the level of abstraction of spreadsheets by
"redrawing the boundary" of the cell. To expose the hidden linkage structure we
transform spreadsheets into fine-grained graphs with operators and values as
nodes. "cells" are then represented as hypergraph edges by drawing a boundary
"wall" around a set of operator/data nodes. To extend what cells may contain
and to create a higher level model of the spreadsheet we propose that
researchers should seek techniques to redraw these boundaries to create higher
level "cells" which will more faithfully represent the end-user's real
world/mental model. We illustrate this approach via common sub-expression
identification and the application of sub-tree isomorphisms for the detection
of vector (array) operations.
