There are several lower level tools that manage and provide access to distributed databases and file systems. However, these tools offer only low level interfaces, or limited to browsing and transferring the data between Grid sites. This paper describes how data can be fed into and utilised in data driven computational workflows. The workflow engine of the P-GRADE Grid portal is used as an implementation platform to be integrated with different Grid data solutions. As an example, the paper describes how the portal and the workflow engine have been integrated with the SDSC Storage Resource Broker (SRB) in order to utilise SRB data resources as both inputs and outputs of workflow components. The solution automates data interaction in computational workflows allowing users to seamlessly access and process data stored in SRB resources.
