Abstract:
Development of composite workflow applications in science and engineering is troublesome and costly due to
high heterogeneity of data representations and data access interfaces of the underlying individual components.
As an effective solution we present a generic toolkit enabling domain experts to develop data models and
automatically generate a self-contained data access service. We defined a custom metamodel based on Ecore
which can be readily used to create domain-specific data models. Using the generated data access service,
instances of the modeled data residing on heterogeneous and distributed resources, such as databases and
cloud data stores, are accessible from the individual application components via a language-independent Web
service interface. We discuss the framework architecture, the toolkit implementation, the deployment process,
as well as the performance of the data access service. Workflow designers as target users would benefit from
the toolkit by using it for rap
id and cost-efficient application integration.
