Abstract: Facing with the ever-growing demand for managing unstructured data, this paper proposes a free-table data model and a reference framework BUD (bank of unstructured data), and further implements a prototype platform MyBUD based on the free-table and BUD. It also proposes a novel method to adaptively select a storage sub-system in MyBUD, which manipulates the specific type of unstructured data more efficiently according to its features. In experiment, the paper sets up a TPCC benchmark and a large volume of unstructured video data to evaluate its performance while managing different co-existing categories of data. The experimental results show that the proposed algorithm provides efficient storage service and establishes foundation for further research on unified management of structured and unstructured data in the database approach.
