Abstract

The purpose of this research is to extend the functionality of MIDAS-III, the storage system of the BADA DBMS developed at ETRI, in order to support multimedia stream data. Currently, MIDAS-III supports only non-continuous data types such as ordinary data files, BLOB and CLOB. We present a new storage structure designed to improve I/O performance for the new continuous data type. Also we present a new two-level disk scheduler that uses prefetching of multimedia stream data to reduce the number of disk seeks. By using prefetching it does not need to provide high priority to stream data requests, and thus it can process more disk access requests in a given time period.
