Harnessing Replication In Object Allocation

H. T. Barney, G. C. Low
2008 Zenodo  
For instance object replication has the potential to greatly improve the performance of an object orientated distributed system but can be difficult to use effectively and there are few techniques that  ...  Techniques have been proposed for both the partitioning and allocation process. However these techniques suffer from a number of limitations.  ...  CONCLUSION Several allocation techniques were surveyed from not only the object orientated world but also databases and non-object orientated distributed systems.  ...

HEURISTIC ALGORITHM FOR FRAGMENTATION AND ALLOCATION IN DISTRIBUTED OBJECT ORIENTED DATABASE

Nga Thúy Mai
2016 Journal of Computer Science and Cybernetics  
Class fragmentation and allocation is an important technique to improve the performance of a distributed object oriented database system.  ...  With such characteristics, class fragmentation and allocation in the distributed object oriented database system is more complex than fragmentation technique and design of relational databases.  ...  OODBs were developed in network environments then made up of distributed object-oriented databases (DOODBs).  ...

An Object-Oriented view of fragmented data processing for fault and intrusion tolerance in distributed systems [chapter]

Jean-Charles Fabre, Brian Randell
1992 Lecture Notes in Computer Science  
This paper describes a technique, called Object-Oriented Fragmented Data Processing, for jointly improving the reliability and security with which distributed computing systems process sensitive information  ...  This technique can be applied to application objects and/or to the objects used in the implementation of the basic object-oriented system.  ...  It would provide to an intruder a partial view on the meeting object, similar to the notion of views used in multilevel security in object-oriented database systems [19] .  ...
