A compositional framework for complex queries over uncertain data
The ability to flexibly compose confidence computation with the operations of relational algebra is an important feature of probabilistic database query languages. Computing confi...

Spreadsheets in RDBMS for OLAP
One of the critical deficiencies of SQL is lack of support for ndimensional array-based computations which are frequent in OLAP environments. Relational OLAP (ROLAP) applications ...

Shape Analysis for Composite Data Structures
We propose a shape analysis that adapts to some of the complex composite data structures found in industrial systems-level programs. Examples of such data structures include “cyc...

Enumeration of Context-Free Languages and Related Structures
In this paper, we consider the enumeration of context-free languages. In particular, for any reasonable descriptional complexity measure for context-free grammars, we demonstrate ...
