Program Analysis and Transformation for Data-Intensive System Evolution

Author: Anthony Cleve

Date: 2009

Abstract

Data-intensive software systems are generally made of a database (sometimes in the form of a set of files) and a collection of application programs in strong interaction with the former. They constitute critical assets in most enterprises, since they support business activities in all production and management domains. Data-intensive systems form most of the so-called legacy systems: they typically are one or more decade old, they are very large, heterogeneous and highly complex. Many of them significantly resist modifications and change due to the lack of documentation, to the use of aging technologies and to inflexible architectures. Therefore, the evolution of data-intensive systems clearly calls for automated support. This thesis particularly explores the use of automated program analysis and transformation techniques in support to the evolution of the database component of the system. The program analysis techniques aim to ease the database evolution process, by helping the developers to understand the data structures that are to be changed, despite the lack of precise and up-to-date documentation. The objective of the program transformation techniques is to support the adaptation of the application programs to the new database. This adaptation process is studied in the context of two realistic database evolution scenarios, namely database platform migration and database schema refactoring.

Database engineering process modelling

Author: Didier Roland

Date: 2002

Abstract

An important research subject in Software engineering is concerned with modelling the development process of huge software in order to bring some help to engineers when designing and maintaining an application. In general, every design process is seen a rational application of transformation operators to one or more products (mainly specifications) in order to produce new products that satisfy some given criteria: O=f(I). I and O being sets of products compliant with formalisable models, f is a transformation composition whose specifications are the properties of I and O. This modelling is a sound basis for a methodological guidance. Indeed, at each step of the process, the set of pertinent activities and types of products are proposed to the designer, without any other.

This guidance can be reinforced with some help. Furthermore, this modelling allows to document the process with its history, i.e. with a representation of performed activities. This history is itself the basis of maintenance activities.

The thesis holds in four phases:

• elaboration of a general model of design processes, a method specification language (MDL), and a history representation
• basic methodological recommendation proposals for the elaboration of engineering methods according to the defined model
• development and integration of some methodological control functions in the DB-MAIN CASE tool, including an extension of the repository, the definition of the interface of the methodological functions, the development of the methodological engine and the development of history processors (recording, replay, analysis,...)
• evaluation of this model with case studies using classical methods.
