Accommodating imprecision in database systems

Amihai Motro
1990 SIGMOD record  
In reality, however, these assumptions are often invalid, and in recent years considerable attention has been given to issues of imprecision in database systems.  ...  Most database systems are designed under assumptions of precision of both the data stored in their databases, and the requests to retrieve data.  ...  Tiffs may have had a chilling impact on further implementations. Another hindrance for database systems with imprecision capabilities may lie in the expectations of users.  ...

1994 Proceedings of the ninth annual conference on Object-oriented programming systems, language, and applications - OOPSLA '94  
Our algorithm extends the analysis in response to discovered imprecisions, guiding the analysis' effort to where it is most productive.  ...  Previous work has shown that constraint-based type inference systems can be used to safely approximate concrete types [15], but their use can be expensive and their results imprecise.  ...  The goal of the Concert System is to develop portable efficient implementations of concurrent object-oriented languages on parallel machines.  ...
