We propose a theory for describing, reasoning about, and simulating transaction models that relax some of the ACID properties of classical transactions. Such models have been proposed for database applications involving long-lived, endless, and cooperative activities. Our approach appeals to non-Markovian theories, in which one may refer to past states other than the previous one. We illustrate...

We develop a unified framework for dealing with constructibility and absoluteness in set theory, decidability of relations in effective structures (like the natural numbers), and domain independence of queries in database theory. Our framework and results suggest that domain-independence and absoluteness might be the key notions in a general theory of constructibility, predicativity, and comput...

With the advent of XML and its use as a database language, dependency and normal form theory has attracted novel research interest. Several approaches to build up a dependency and normal form theory for XML databases have been published, mainly concentrating on functional dependencies and keys. XMLlike database structures can be modelled by rational trees using constructors for lists and disjoi...

As an increasing amount of data is gathered nowadays and stored in databases, the question arises of how to protect the privacy of individual records in a database even while providing accurate answers to queries on the database. Differential Privacy (DP) has gained acceptance as a framework to quantify vulnerability of algorithms to privacy breaches. We consider the problem of how to sanitize ...

introduction: consumers have referred to the web to learn how they can improve their health, prevent disease and learn details about specific diseases. while efforts are being made to monitor information found on the web especially with the emergence of her: electronic health record in iran, they are not enough to cover every web site with health information. as a result, it was decided to eval...

This book contains valuable information and commonsense ideas for anyone who is involved with the upbringing of children. It is clearly written and very readable. Dr. de Kok has the happy knack of being able to translate highly complicated psychological theories into everyday language. Here is a book written by an expert which the average parent can read easily without the "mumbo jumbo" of psyc...

Protection of privacy in databases has become of increasing importance. While a number of techniques have been proposed to query databases while preserving privacy of individual records in the database, very little is done to define a measure on how much privacy is lost after statistical releases. We suggest a definition based on information theory. Intuitively, the privacy loss is proportional...
