On data dependencies in dataspaces
2011 IEEE 27th International Conference on Data Engineering, 2011To study data dependencies over heterogeneous data in dataspaces, we define a general dependency form, namely comparable dependencies (CDs), which specifies constraints on comparable attributes. It covers the semantics of a broad class of dependencies in databases, including functional dependencies (FDs), metric functional dependencies (MFDs), and ...

If you can't make your data dependable, then you can't make your computing dependable, either. The good news is that the list of data protection techniques is long, and growing. The bad news is that the choices they offer are getting more complicated: how many copies of data to keep? whether to use full or partial redundancy?

Conversion of control dependence to data dependence
Proceedings of the 10th ACM SIGACT-SIGPLAN symposium on Principles of programming languages - POPL '83, 1983Program analysis methods, especially those which support automatic vectorization, are based on the concept of interstatement dependence where a dependence holds between two statements when one of the statements computes values needed by the other. Powerful program transformation systems that convert sequential programs to a form more suitable for ...

Fragmentation in Presence of Data Dependencies
IEEE Transactions on Dependable and Secure Computing, 2014Fragmentation has been recently proposed as a promising approach to protect the confidentiality of sensitive associations whenever data need to undergo external release or storage. By splitting attributes among different fragments, fragmentation guarantees confidentiality of the associations among these attributes under the assumption that such ...

A Proof Procedure for Data Dependencies
Journal of the ACM, 1984A class of dependencies, tuple and equality generating dependencies, is defined, and the chase process is generalized to deal with these dependencies. For total dependencies the chase is an exponential time decision procedure for the implication problem, and in some restricted cases it can be modified to run in polynomial time.

Summary: We consider the partial least squares algorithm for dependent data and study the consequences of ignoring the dependence both theoretically and numerically. Ignoring nonstationary dependence struc-tures can lead to inconsistent estimation, but a

Contexts and Data Dependencies: A Synthesis
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1983Two data-organization devices that have come out of AI re-search are data pools (``contexts'') and data dependencies. The latter are more flexible than the former, and have supplanted them. Data pools offer certain advantages of efficiency, however, so it is worth trying to make the two mechanisms compatible.

Effects of pointers on data dependences
Proceedings 9th International Workshop on Program Comprehension. IWPC 2001, 2002This paper presents a technique for computing and classifying data dependences that takes into account the complexities introduced by specific language constructs, such as pointers, arrays and structures. The classification is finer-grained than previously proposed classifications.
