Feature-Oriented Programming (FOP) is both a design methodology and supporting tools for program synthesis. The goal is to specify a target program in terms of the features that it offers, and to synthesize an efficient program that meets these specifications. FOP has been used successfully to develop product lines in widely varying real-world domains, including compilers for extensible Java dialects, fire support simulators for the U.S. Army, network protocols, and program verification tools.

AHEAD is a simple mathematical model of FOP that is based on step-wise refinement, a methodology for building programs by adding one feature at a time. The incremental units of implementation/design are refinements that encapsulate the implementation of an individual feature. AHEAD models of product lines treat base programs as constants and program refinements as functions (that add a specified feature to the input program). Application designs are thus equations--compositions of functions and constants--that are amenable to optimization and analysis.

This tutorial reviews basic results on FOP, including general models and tools for synthesizing a consistent set of code and non-code artifacts by composing refinements (cross-cuts), automatic algorithms for validating refinement compositions, synthesizing product-lines of product-families (e.g., tool suites), and automatic algorithms for optimizing application designs (equations).

Presenter

Don Batory holds the David Bruton Centennial Professorship at The University of Texas at Austin. He received a B.S. (1975) and M.Sc. (1977) degrees from Case Institute of Technology, and a Ph.D. (1980) from the University of Toronto. He was a faculty member at the University of Florida in 1981 before he joined the Department of Computer Sciences at the University of Texas in 1983.

He was an Associate Editor of IEEE Transactions on Software Engineering (1999-2002), Associate Editor of ACM Transactions on Database Systems (1986-1992), a member of the ACM Software Systems Award Committee (1989-1993; Committee Chairman in 1992), Program Co-Chair for the 2002 Generative Programming and Component Engineering Conference, the Program Chair for the 1995 International Conference on Software Reuse, and the 1999 Workshop on Software Reuse. He has given numerous lectures and tutorials on product-line architectures, generators, and reuse, and is an industry consultant on product lines.
