Wrapper-based evolution of legacy information systems

Philippe Thiran, Jean-Luc Hainaut, Geert-Jan Houben, Djamal Benslimane
2006 ACM Transactions on Software Engineering and Methodology  
For instance, incorporating a new program in a legacy database application can create an integrity mismatch, since the database model and the program data view can be quite different (e.g. standard file  ...  In addition, neither the legacy DBMS (too weak to address integrity issues correctly) nor the new program (that relies on data server responsibility) correctly cope with data integrity management.  ...  Transformations can be used to transform a schema from one model to another one, requiring specific operators for this couple of models. In , we define a set of transformations valid for GER schemas.  ...

ModifRoundtrip: A Model-Based tool to reuse legacy transformations

Paola Vallejo, Jean-Philippe Babau, Mickaël Kerboeuf
2016 ACM/IEEE International Conference on Model Driven Engineering Languages and Systems  
In this approach, the data conforming to the reuse context coevolve into data conforming to the legacy transformation context.  ...  Nevertheless, in many cases, have to be rewritten in order to make them apply to semantically equivalent but structurally incompatible data.  ...  However, even if legacy transformations are available, reusing them within the scope of a given DSML raises two problems: the adaptation of DSML data structures (user oriented) into legacy transformation  ...

Leveraging legacy system dollars for e-business

L. Erlikh
2000 IT Professional Magazine  
Understanding a legacy system's structure and operations is critical to transforming it intelligently to the new architecture.  ...  How a healthcare provider used RescueWare to transform its claims processing system to e-components. The legacy system consisted of a Cobol batch system that collected data from 20 outside agencies.  ...

Reengineering Legacy to Modern System with One Time Checker for Information System Evolution

Sudhakar
2012 American Journal of Applied Sciences  
This approach was developed to impose the dynamic program slicing as a method, which was basically used for simplifying programs by focusing on selected aspects of semantics.  ...  Approach: In this respect to improve efficiency and decrease complexity, we propose a Reengineering model namely Reengineering Legacy to Modern (RL2M) system.  ...  Legacy systems can be used on various models ranging from standard file structures to relational and data models.  ...

Legacy System Integration using a Grammar-Based Transformation System

Guido Menkhaus, Urs Frei
2004 Journal of Computing and Information Technology  
These legacy systems produce structured or semi-structured data that add to the vast amounts of data a company generates every day.  ...  This article presents a transformation system that uses a grammar-based approach to provide direct integration of applications and systems at the data level.  ...  Each command consists of a set of views and of a controller. The controller connects to the model and decides which view renders data from the model.  ...

Using high-level algebraic models allows describing program transformations in a more concise manner. Performance measurements demonstrate high efficiency of obtained parallel programs.  ...  Our approach is to use rewriting rules technique in order to automate the transformation process.  ...  Further research directions include development of the same approach for transforming legacy Fortran applications to target distributed-memory systems and GPUs.  ...
