Data intensive domains are commonly overwhelmed with the vast and increasing amount of information available. Advanced studies in biomedicine or earth observation, for example, often require a considerable amount of effort to achieve data access to a critical mass of information to analyze the problem at hand. In this context we propose a novel application of QoS mechanisms previously used with computing services and now applied to data services. The proposed approach supports negotiable guarantees with respect to data quantity and quality for data access in advance of the actual data retrieval. Therefore, new data-related service level objectives (SLOs) are introduced and an according QoS management model is presented. This model resolves the complex process of the service level agreement (SLA) generation within data access and data mediation services. The benefits of this approach are materialized in the context of the data acquired in large biomedical project, an initial experimental evaluation demonstrates promising performance improvements in a real world scenario.
