One of the problems arising upon the evolution of a database schema is that some queries
and views defined on the previous schema version might no longer work properly. Thus …

Current antigenic targets for influenza vaccine development are either highly immunogenic
epitopes of high variability or conserved epitopes of low immunogenicity. This requires …

Rewriting is a versatile and powerful technique used in many domains. Strategic rewriting
allows programmers to control the application of rewrite rules by composing individual …

This paper proposes and validates a model-driven software engineering technique for
spreadsheets. The technique that we envision builds on the embedding of spreadsheet …

Spreadsheets are notoriously error-prone. To help avoid the introduction of errors when
changing spreadsheets, models that capture the structure and interdependencies of …

Coupled transformation occurs when multiple software artifacts must be transformed in such
a way that they remain consistent with each other. For instance, when a database schema is …

This paper addresses the foundations of data-model transformation. A catalog of data
mappings is presented which includes abstraction and representation relations and …

Spreadsheets can be viewed as programming languages for non-professional
programmers. These so-called “end-user” programmers vastly outnumber professional …

These tutorial notes present a methodology for spreadsheet engineering. First, we present
data mining and database techniques to reason about spreadsheet data. These techniques …

Traversal strategies à la Stratego (also à la Strafunski and 'Scrap Your Boilerplate') provide
an exceptionally versatile and uniform means of querying and transforming deeply nested …
