Storage system architectures for continuous media data
changes in the form of requests and responses at the application-database and database-OS interfaces
new kinds of abstractions and data independence that data mangement systems will need to supply, such as quality-of-service requests and mapping of domain events to OS events
effects of CLSA demands on query optimization, planning and evaluation, including the need for accurate resource estimates and detailed schedules
new information requirements for the database system, such as better characterizations of storage subsystem performance and application patterns.
We illustrate the problems and new demands of continuous media access with application requirements of an all-digital television production studio of the future. We conclude by presenting a storage architecture we are pursuing that we believe will support “scripted” CLSA to shared data.
