It is also discussed how DDBS applications can take advantage of lenient isolation Apotram transactions. Anfindsen, O J. 1995. Parameterized access modes in Apotram. Telektronikk , Vol 91, No 4, 153-162. Parameterized access modes may be thought of as a generalization of the well known concept of isolation levels, and enables dynamic cooperation between database transactions without requiring interaction patterns to be predefined.
Uncommitted data is considered to be a special case of unreliable data.
The quality of uncommitted data is represented by means of reliability indicators. The latter, possibly combined with logic, is used as a language for communication between cooperating transactions. This is an extended and modified version of the the paper Dynamic cooperation between database transactions by means of generalized isolation levels . Special issue on Intelligent Networks. Special issue on Cyberspace.
