We show how model extensibility of object-oriented data management systems can be achieved through the combination of a highlevel core object data model and an architecture designe...
The supercomputer center, digital library, and archival storage communities have common persistent archival storage requirements. Each of these communities is building software in...
The objective of this paper is to describe the use of a probabilistic approach to Web effort estimation by means of a Bayesian Network. A Bayesian Network is a model that embodies ...
imizer Communication using Abstract Plans in Sybase ASE Query optimizers are error prone, due to both their nature and the increased search space that modern query processing requ...
Currently the key problems of query optimization are extensibility imposed by object-relational technology, as well as query complexity caused by forthcoming applications, such as...
