چکیده
Traditional modular redundancy based upon software fault tolerance techniques, such as N-version programming and recovery blocks, is now widely known and its use is on the increase. By contrast, data fault tolerance techniques have been largely ignored. The most likely reason for this omission is the perception that implementations are highly complex. Fortunately this situation has been greatly improved by object oriented systems which supply many of the required facilities. These allow data fault tolerance techniques to take their place alongside software design diversity techniques. Currently the areas of software fault tolerance and object-oriented techniques have been developed separately. This paper describes an approach to merge these two areas, providing a framework to utilise object-oriented approaches to achieve software fault tolerance incorporating both design and data diversity techniques.

Fault Proneness of Classes in Object-oriented Systems
Predicting fault proneness of classes in object oriented systems (OOS) is one of the fault management activities and may be considered as one of the cost effective ways to deal with faults. Prediction of faults needs identification and measurement of various factors that affects fault proneness of classes in OOS. In this paper, several design oriented factors have been identified that help in c...
متن کاملTroubleshooting Microprocessor Based System using An Object Oriented Expert System
The paper presents an object oriented fault diagnostic expert system framework which analyses observations from the unit under test when fault occurs and infers the causes of failures. The frame work is characterized by two basic features. The first includes a fault diagnostic strategy which utilizes the fault classification and checks knowledge about unit under test. The fault classification k...
متن کاملToward an Object-Oriented Approach to Software Fault Tolerance
Software fault tolerance is often necessary, but can itself be dangerously error-prone because of the additional effort that must be involved in the programming process. The additional redundancy may increase size and complexity and thus adversely affect software reliability. Object-oriented programming provides an appropriate framework for controlling complexity and enforcing reliability. Howe...
متن کاملA hybrid approach for the prediction of fault proneness in object oriented design using fuzzy logic
Empirical studies conducted by the researchers on object-oriented design metrics are useful for forecasting the fault-proneness of classes in object-oriented design. In this study, we propose an integrated hybrid model to empirically investigate the fault-proneness of object-oriented design. We will use a subset of the Chidamber and Kemerer suite and all of the MOOD metrics to predict fault-pro...
متن کاملAdding Group Communication and Fault-Tolerance to CORBA
Groupware and fault-tolerant distributed systems stimulate the need for structuring activities around objectgroups and reliablemulticast communication. The objectgroup abstraction permits to treat a collection of networkobjects as if they were a single object; clients can invoke operations on object-groups without needing to know the exact membership of the group. Object-groups mainly serve to ...
