Algorithms for Data Management and Migration

Algorithms for Data Management and Migration

by Samir Khuller - January 23 (2008)

Algorithms for Data Management and Migration - ABSTRACT:
"I will describe some algorithms for addressing some fundamental optimization
problems that arise in the context of data storage and management. In the
first part of the talk we will address the following question: How should
we store data in order to effectively cope with non-uniform demand for
data? How many copies of popular data objects do we need? Where should
we store them for effective load balancing?"
