We formalize and study business process systems that are centered around" business
artifacts", or simply" artifacts". Artifacts are used to represent (real or conceptual) key …

We study the static verification problem for data-centric business processes, specified in a
variant of IBM's “business artifact” model. Artifacts are records of variables that correspond to …

We present an overview of results on verification of temporal properties of infinite-state
transition systems arising from processes that carry and manipulate unbounded data. The …

We describe a novel approach to verification of software systems centered around an
underlying database. Instead of applying general-purpose techniques with only partial …

Software systems centered around a database are pervasive in numerous applications.
They are encountered in areas as diverse as electronic commerce, e-government, scientific …

We introduce a new decidable logic for reasoning about infinite arrays of integers. The logic
is in the ∃^*∀^* first-order fragment and allows (1) Presburger constraints on existentially …

Recent years have witnessed the evolution of business process specification frameworks
from the traditional process-centric approach towards data-awareness. Process-centric …

In this paper we work over linearly ordered data domains equipped with finitely many unary
predicates and constants. We consider nondeterministic automata processing words and …

We introduce a uniform framework for reasoning about infinite-state systems with
unbounded control structures and unbounded data domains. Our framework is based on …

We study complexity issues related to the model-checking problem for LTL with registers
(aka freeze LTL) over one-counter automata. We consider several classes of one-counter …
