Astronomical data resources have features of long-term accumulation, high volume, distributed storage, and managed by diverse database software. One of the important goals in Virtual Observatory (VO) is to provide a uniform way to access these distributed and heterogeneous data resources for astronomers. A grid solution (Virtual Observatory Data Access Service, VO-DAS) is designed in this paper. Astronomical catalogue data, image data and spectroscopy data, which have different metadata, are wrapped by Open Grid Service Architecture - Database Access and Integration [OGSA-DAI] (DataNode). VO-DAS implements automatic discovery of DataNodes and supports federation data access upon them. This makes it possible for multi-band cross matching of astronomical objects. VO-DAS supports related specifications published by International Virtual Observatory Alliance (IVOA) so that interoperability is achieved. A series of simple and efficient application interfaces are designed for developing versatile high-level applications based on VO-DAS. Two science cases based on VO-DAS confirm its feasibility.
