Abstract
One of the issues in distributed databases is to maintain the data consistency when a database is replicated for higher availability. In a real-time database system, availability may be more important than consistency since a result must be produced before a deadline. We propose techniques to increase the availability in a partitioned real-time database. We also suggest that a transaction may execute even when the most up-to-date information is not available or when a serializable execution cannot be guaranteed. As long as data integrity is maintained, serializable execution may not be necessary.Keywords
