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.

The action workflow approach to workflow management technology
Proceedings of the 1992 ACM conference on Computer-supported cooperative work - CSCW '92, 1992Abstract This paper describes the ActionWorkflow™ approach to workflow management technology: a design methodology and associated computer software for the support of work in organizations. The approach is based on theories of communicative activity as language/action, developed in a series of systems for coordination among users of networked computers.

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.

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.

This chapter describes lightweight workflow as a possible approach to counter many of the issues related to the introduction and sustained use of operational workflow management systems. Aside from a description of the essential features of lightweight workflow, this chapter also provides a reflection on the application of lightweight workflow in ...

Conventional workflow functionality like task sequencing, split parallelism, join synchronization and iteration have proven effective for business process automation and have widespread support in current workflow products. However, newer requirements for workflows are encountered in practice, opening grave uncertainties about the extensions for ...

Summary: Serializability as an isolation criterion, though well suitable for traditional transactions, would overly restrict the concurrency of long lasting activities such as workflows. By using semantic information it is possible to weaken, or give up altogether, the serializability criterion and yet ensure workflow execution correctness. The problem,
