Dynamic Tree Bitmap for IP Lookup and Update
We propose a data structure–dynamic tree bitmap–for the representation of dynamic IP router tables that must support very high lookup and update rates. In fact, the dynamic tr...

Positional update handling in column stores
In this paper we investigate techniques that allow for on-line updates to columnar databases, leaving intact their high read-only performance. Rather than keeping differential str...

Fast local searches and updates in bounded universes
Given a bounded universe {0, 1, . . . , U-1}, we show how to perform (successor) searches in O(log log ) expected time and updates in O(log log ) expected amortized time, where i...

Tableaux for Reasoning About Atomic Updates
A simple model of dynamic databases is studied from a modal logic perspecitve. A state α of a database is an atomic update of a state β if at most one atomic statement is evaluat...
