Client Cache Management in a Distributed Object Database Client Cache Management in a Distributed Object Database

A distributed object database stores objects persistently at servers. Applications run on client machines, fetching objects into a client-side cache of objects. If fetching and cache management are done in terms of objects, rather than xed-size units such as pages, three problems must be solved: 1. which objects to prefetch, 2. how to translate, or swizzle, inter-object references when they are...

Trends in Distributed and Cooperative Database Management

PC/workstation DBMS provide a set of data management functions in a stand-alone fashion as a single-user system on a personal computer or workstation. There is no real data exchange between a PC/workstation DBMS and other data management systems, remote users, or DBMS at another place. Some PC/workstation DBMS provide limited functions to extract data as a "snapshot" from a remote database to p...

Building a Distributed Database with Device-Served Leases

This paper describes a method for constructing a distributed database from a set of compute-nodes, a local area network, and a set of object-disks. We assume object-disks do not fail; nodes can fail or go to sleep for long periods. In order for a node to access an object inside an object-disk a valid lease is required. There are two issues that need resolving (1) how to build a database on top ...
