We review two surveys of large-scale system management, observing common problems across tools and over many years. We also note that filesystem management tools interfere with filesystem integrity checking tools. Radmind, an integrated filesystem management and integrity checking tool, solves many of these problems. Radmind also provides a useful platform upon which to build further large-scal...

Functional dependencies (FDs) are integrity constraints widely studied in the context of data profiling. In this work, we explore the automatic discovery of FDs and describe a method for selecting relevant ones regarding workload semantics. The experimental evaluation shows that the selected dependencies exhibit expressive properties compared to the search space, which demonstrates the effectiv...

A two-step optimization strategy for relational schemas that contains a class of inclusion dependencies is described. Both steps take into account additional information that indicates how to preserve each inclusion dependency in the presence of insertions an‘d deletioy. The first step eliminates inclusion dependencies which are redundant with respect to both the semantics of the data and the b...

background: sperm selection for icsi based on morphology and motility might not be relevant to chromatin integrity. thus sperm selection based on sperm characteristics has been suggested. objective: the aim of this study was to compare the efficiency of zeta method with routine density gradient centrifugation method (dgc) for the selection of sperm with higher dna integrity. materials and metho...

Integrity constraints in databases have been studied extensively since the 1980s, and they are considered essential to guarantee database integrity. In recent years, several authors have studied how the same notion can be adapted to reasoning frameworks, in such a way that they achieve the purpose of guaranteeing a system’s consistency, but are kept separate from the reasoning mechanisms. In th...

Loan servicers today face increasing regulatory and investor pressures to make sure they properly protect and preserve the integrity of their loan records. Data security and data integrity, unfortunately, are two often-overlooked aspects of loan servicing. Failure in either area is a recipe for reputation damage at best, and financial disaster, at worst. The goal of this paper is to provide loa...

Much useful new information (e.g. information in news reports) is often that which is surprising or unexpected. In other words, we harbour many expectations about the world, and when any of these expectations are violated (i.e. made inconsistent) by new information, we have a strong indicator that the information is interesting for us. An expectation can be compared with an integrity constraint...

The core of a model theory for generic schema management is developed. This theory has two distinctive features: it applies to a variety of categories of schemas, and it applies to transformations of both the schema structure and its integrity constraints. A subtle problem of schema integration is considered in its general form, not bound to any particular category of schemas. The proposed solu...
