The problem of database consistency relative to a set of integrity constraints has been extensively studied since the 1980s, and is still recognized as one of the most important and complex in the field. In recent years, with the proliferation of knowledge repositories (not only databases) in ...
The design and implementation of a repository for the management of spatial data integrity constraints This paper reviews the key features of an environment to support domain users in spatial information system (SIS) development. It presents a full design an... S Cockcroft - 《Geoinformatica》 被...

Inadequate Resources: Insufficient financial or technological resources can impede the successful execution of a strategy. Organizations may face budget constraints, a lack of skilled personnel, or outdated technology that hinders implementation efforts. Poor Communication: Ineffective communication can lead to...
To obtain intermetallic capacitors for removing switching noises that pollute function of a power supplier, by leaving two layers, which can be biased, on one of both metallization levels interposing the intermetallic capacitors as well as on one of the metallization levels on the side of a circui...

Research suggests that institutions affect the levels of corruption in a country. We take these arguments a step further and examine whether it is the pres
In resolution step, SLDresolution is applied until the last resolvents consist of either extensional literals or comparison literals. In post-resolution step, intensional answers are generated and checked against integrity constraints to remove meaningless answers. Our work is an extension to Cholvy and...
Import tables consist of: Import Control Fields Online Data Fields Surrogate Key Fields Because import tables are meant to capture as much data as possible, all fields are nullable and there are no integrity constraints such as primary-key definitions, unique indexes, or foreign-key references. Th...
Autonomous vehicles require efficient self-localisation mechanisms and cameras are the most common sensors due to their low cost and rich input. However, the computational intensity of visual localisation varies depending on the environment and requires
