Inconsistency handling in multiperspective specifications

A.C.W. Finkelstein, D. Gabbay, A. Hunter, J. Kramer, B. Nuseibeh
1994 IEEE Transactions on Software Engineering  
This paper presents our technique for inconsistency handling in the ViewPoints framework by using simple examples.  ...  Indeed since the real-world forces us to work with inconsistencies, we should formalise some of the usually informal or extra-logical ways of responding to them.  ...  The problem of inconsistency handling in the ViewPoints framework can then be viewed as being equivalent to inconsistency handling in distributed logical databases.  ...

Introduction to Inconsistency Tolerance [chapter]

Leopoldo Bertossi, Anthony Hunter, Torsten Schaub
2005 Lecture Notes in Computer Science  
To address this, inconsistency tolerance is being built on foundational technologies for identifying and analysing inconsistency in information, for representing and reasoning with inconsistent information  ...  Whether inconsistency is unwanted or useful, there is a need to develop tolerance to inconsistency in application technologies such as databases, knowledgebases, and software systems.  ...  The idea, as opposed to traditional approaches to inconsistency handling, is to live with an inconsistent database, but obtaining only consistent information (with respect to given integrity constraints  ...

Managing inconsistent specifications: reasoning, analysis, and action

Anthony Hunter, Bashar Nuseibeh
1998 ACM Transactions on Software Engineering and Methodology  
T o support this, we h a ve used classical logic to represent partial speci cations and to identify inconsistencies between them.  ...  Finally, w e discuss further the notion of acting in the presence of inconsistency, and examine the use of meta-level inconsistency handling rules to support such action.  ...  This work was partially funded by the UK EPSRC as part of the Voila project (GR J15483), the CEC as part of the Basic Research Actions Promoter and Drums II, and the ISI project (ECAUS003).  ...

2014 International Journal of Computer Science and Informatics  
In this paper, we develop an approach that can handle data inconsistencies and identify a number of issues with compensation-based transaction protocols and describe another transaction protocol that addresses  ...  Such applications often involve distributed databases that have developed independently and therefore may exhibit incompatibility, heterogeneity, and data inconsistency.  ...  Aggregate views of Distributed Databases.  ...

The process of inconsistency management: a framework for understanding

B. Nuseibeh, S. Easterbrook
1999 Proceedings. Tenth International Workshop on Database and Expert Systems Applications. DEXA 99  
These are supported by the processes of measuring inconsistency, and analyzing the impact and risk associated with different inconsistency handling options.  ...  The process of managing inconsistency is a fundamental activity that permeates a large part of the systems development process.  ...  We have outlined some of the activities that are involved in inconsistency management, and highlighted inconsistency handling strategies that allow living with inconsistency.  ...

Data Consistency Enforcement on Business Process Transactions [chapter]

As measured in Section 3.2, it actually takes only 315ms to actively resolve the inconsistencies. In the third experiment, we evaluate ACM for its consistency adaptability.  ...  As a result, it is almost impossible to compare the guarantees provided by each system. 132 Copyright ⓒ 2015 SERSC the ACM active inconsistency resolution and the "system average" curve is the average  ...  For instance, a partial system failure of an ACID system might reject write operations, forcing the application to handle the data to be written somehow.  ...
