Type-safe Computation with Heterogeneous Data

Huang, Freeman Yufei 14 September 2007 (has links)
Computation with large-scale heterogeneous data typically requires universal traversal to search for all occurrences of a substructure that matches a possibly complex search pattern, whose context may be different in different places within the data. Both aspects cause difficulty for existing general-purpose programming languages, because these languages are designed for homogeneous data and have problems typing the different substructures in heterogeneous data, and the complex patterns to match with the substructures. Programmers either have to hard-code the structures and search patterns, preventing programs from being reusable and scalable, or have to use low-level untyped programming or programming with special-purpose query languages, opening the door to type mismatches that cause a high risk of program correctness and security problems. This thesis invents the concept of pattern structures, and proposes a general solution to the above problems - a programming technique using pattern structures. In this solution, well-typed pattern structures are defined to represent complex search patterns, and pattern searching over heterogeneous data is programmed with pattern parameters, in a statically-typed language that supports first-class typing of structures and patterns. The resulting programs are statically-typed, highly reusable for different data structures and different patterns, and highly scalable in terms of the complexity of data structures and patterns. Adding new kinds of patterns for an application no longer requires changing the language in use or creating new ones, but is only a programming task. The thesis demonstrates the application of this approach to, and its advantages in, two important examples of computation with heterogeneous data, i.e., XML data processing and Java bytecode analysis. / Thesis (Ph.D, Computing) -- Queen's University, 2007-08-27 09:43:38.888

Safe Template Processing of XML Documents

Hartmann, Falk 01 July 2011 (has links)
Templates sind eine etablierte Technik zur Zusammenführung verschiedener Datenquellen, welche zum Zwecke der Separation of Concerns getrennt gehalten werden sollen. Bei der Benutzung bestehender Ansätze tritt das Problem auf, dass zur Zeit der Erstellung eines Templates keine Aussagen über die Ergebnisse der Ausprägung des Templates gemacht werden können. Die Arbeit konzipiert einen alternativen Template-Ansatz und setzt diesen für XML-basierte Zielsprachen um. Die dadurch ermöglichte sichere templategestützte Verarbeitung von XML-Dokumenten zeichnet sich durch dadurch aus, das bereits zur Erstellungszeit eines Templates Aussagen über das Ergebnis der Template-Ausprägung getroffen werden können. Darüber hinaus adressiert der neue Ansatz weitere Fehlerquellen, welche typischerweise bei der Ausprägung von Templates auftreten.
