On Transactional Workflows. [PDF]
IEEE Data Eng. Bull., 1993 The basic transaction model has evolved over time to incorporate more complex transactions structures and to take the advantage of semantics of higher-level operations that cannot be seen at the level of page reads and writes. Well known examples of such extended transaction models include nested and multi-level transactions.

Scientific workflow management systems and workflow patterns
International Journal of Business Process Integration and Management, 2010Scientific workflow management systems primarily consist of data flow oriented execution models, and consequently, these systems provide a limited number of control flow constructs that are represented in dissimilar ways across different scientific workflow systems.

Workflow ART: a framework for multidimensional workflow analysis
Enterprise Information Systems, 2013Business processes are obliged to follow numerous constraints, such as compliance regulations, service level agreements, security regulations and budget constraints. To be able to understand relations between different constraint types and their impact on the business, a common constraint specification framework is required.

Timing constraint workflow nets for workflow analysis
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2003The analysis of the correctness and rationality of a workflow model plays an important role in the research of workflow techniques and successful implementation of workflow management. This paper points out the relevant problems in the verification and analysis of a workflow model.

Workflow Testing and Workflow Engineering
2009When there is too much work and too few personnel, there are two main options: hire more staff or improve the efficiency of the existing employees. Generally, it is much cheaper and more satisfying to improve efficiency by identifying and removing workflow bottlenecks.

Dynamic workflow management: a framework for modeling workflows
Proceedings of the Thirtieth Hawaii International Conference on System Sciences, 2002Current workflow management systems do not provide adequate support for workflow modeling. Real life work processes are much richer in variations and more dynamic than is expressed in a typical workflow model. Users need to be able to adjust workloads and modify workflow models on-the-fly.

Dynamic workflow schema evolution based on workflow type versioning and workflow migration
Proceedings Fourth IFCIS International Conference on Cooperative Information Systems. CoopIS 99 (Cat. No.PR00384), 1999An important yet open problem in workflow management is the evolution of workflow schemas, i.e., the creation, deletion and modification of workflow types in such a way that the schema remains correct. This problem is aggravated when instances of modified workflow types are active at the time of modification because any workflow instance has to conform

Conceptual modeling of workflows
1995Workflow management is emerging as a challenging area for databases, stressing database technology beyond its current capabilities. Workflow management systems need to be more integrated with data management technology, in particular as it concerns the access to external databases.
