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  
The component that can reconciliate these mismatched subsystems is the R/W wrapper, which allows any client program to read, but also to update the legacy data, while controlling the integrity constraints  ...  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.  ...  Updating data through such a wrapper poses the problem of guaranteeing legacy data consistency by rejecting updates that violate all the constraints, whether they are implicit or explicit.  ...

Modularized design for wrappers/monitors in data warehouse systems

Jorng-Tzong Horng, Jye Lu
2000 Journal of Systems and Software  
To simplify the task of constructing wrapper/monitor for the information sources in data warehouse systems, we provide a modularized design method to re-use the code.  ...  By substituting some parts of wrapper modules, we can re-use the wrapper on a dierent information source. For each information source, we also develop a toolkit to generate a corresponding monitor.  ...  In WHIPS architecture, view managers can maintain different degrees of consistency by dierent algorithms .  ...

Don't Scrap It, Wrap It! A Wrapper Architecture for Legacy Data Sources

Mary Tork Roth, Peter M. Schwarz
1997 Very Large Data Bases Conference  
Garlic wrappers model legacy data as objects, participate in query planning, and provide standard interfaces for method invocation and query execution.  ...  To date, we have built wrappers for 10 data sources.  ...  Wrappers for new data sources can be integrated into existing Garlic databases without disturbing legacy applications, other wrappers, or existing Garlic applications. 4.  ...

MEADOW: a middleware for efficient access to multiple geographic databases through OpenGIS wrappers

Sang K. Cha, Kihong Kim, Byung S. Lee, Changbin Song, Sangyong Hwang, Yongsik Kwon
2002 Software, Practice & Experience  
We resolved the complexity problem by automatically generating a major portion of the application code, specifically, wrappers on database servers and client library modules called transparent access providers  ...  Main problems are the complexity of system development and maintenance, and the inefficiency of accessing remote data servers for processing region queries.  ...  ACKNOWLEDGEMENT This work was supported in part by the Brain Korea 21 Program for Information Technology at Seoul National University and the Korean GIS database tool development project carried out through  ...

An Introduction to the e-XML Data Integration Suite [chapter]

Georges Gardarin, Antoine Mensch, Anthony Tomasic
2002 Lecture Notes in Computer Science  
This paper describes the e-XML component suite, a modular product for integrating heterogeneous data sources under an XML schema and querying in real-time the integrated information using XQuery, the emerging  ...  server, and finally through the legacy infrastructure.  ...  The use of a Repository for XML data transmitted throughout the system speeds up performance by storing copies of XML data in a central location managed through a main memory database.  ...

Migration of Legacy Information Systems [chapter]

Jean-Luc Hainaut, Anthony Cleve, Jean Henrard, Jean-Marc Hick
2008 Software Evolution  
The first one is the conversion of the database to a new data management paradigm.  ...  More specifically, it studies the substitution of a modern data management technology for a legacy one. Platform migration raises two major issues.  ...  Wrapper-based migration architecture: a wrapper allows the data managed by a new DMS to be accessed by the legacy programs.  ...

Program analysis and transformation for data-intensive system evolution

Anthony Cleve
2010 2010 IEEE International Conference on Software Maintenance  
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.  ...  The wrapper converts all legacy DMS requests from legacy applications into requests against the new DMS that now manages the data.  ...  The wrapper converts all legacy DMS requests from legacy applications into requests against the new DMS that now manages the data.  ...

An Approach to Resolve Data Model Heterogeneities in Multiple Data Sources

C. Chirathamjaree
2006 TENCON 2006 - 2006 IEEE Region 10 Conference  
This paper presents an approach to resolve data model heterogeneities in databases and legacy systems through mediation and wrapping techniques.  ...  The system is well supported by the Mediated Data Model (MDM), a semantically-rich data model which can describe and represent heterogeneous data schematically and semantically.  ...  In fact, some legacy systems store data to flat files, which are completely different in schematic design from database management systems (DBMSs).  ...

models for architecture-based management systems.  ...  Third, our experience also shows that a meta-data checkpointing capability is best-suited for metadata recovery after failures. We demonstrate the soundness of these findings in several ways.  ...  This is required to manage the mapping with the Legacy layer through the specific management interfaces provided by the legacy elements.  ...

A Responsive Client Architecture with Local Object Behavior Deployment [chapter]

Ana Paula V. Pais, O. B. Bárbara, Carlo E. T. Oliveira, Gilson Tavares
2002 Lecture Notes in Computer Science  
Configuration and version management, added to maintenance cost are major players on this decision. However, heavy traffic loads and network latency impose severe pena1ties on users.  ...  A simpler approach to this case is to rely on the data model underlying the legacy system. In most cases, the data model can be extracted from database metadata information.  ...  The Reverse Stunt Architecture is a modification on SA to make use of existing data models. In most of the times, the only existing documentation in legacy systems is the database design.  ...

2011 ACM Transactions on Autonomous and Adaptive Systems  
The contributions of this article are, (1) to explain how JADE provides autonomic management of a distributed system through an architecture-based approach, (2) to explain how we extended autonomic management  ...  from traditional self behaviors such as repairing or protecting a managed system to self-self behaviors where JADE also fully manages itself as it manages any other distributed system, (3) to report on  ...  , and finally to a database system that persistently stores data.  ...
