dc.description.abstract | This paper presents a scheme using the virtual machine concept for-creating:
1) An environment for increasing the effectiveness of researchers who
use analytical, modeling systems and have complex data management needs.
2) A mechanism for multi-user coordination of access and update to a
central data base.
3) A mechanism for creating an environment where several different
modeling facilities can access the same data base.
4) A mechanism for creating an environment where several different and
potentially incompatible data management systems can all be accessed by
the same user models or facilities'.
5) A mechanism for reducing the transport cost of integrating existing
analytical packages and applications programs under a single unified
system..
6) A mechanism for enhancing the data management capabilities of
existing modeling and anlaytical languages.
Also presented is a theoretical analysis of the performance
implications of this scheme specifically directed at the question of response
time degradation as a function of number of virtual machines, of locked
time of the data base machine, and of query rate of the modeling machine.
A discussion of the practical implications of this analysis is given. | en |
