Specifying a Database System to Itself
نویسنده
چکیده
Query processors have long been monolithic pieces of software that resist extension. Query capabilities are needed in many applications of persistent object bases, but object models and storage managers are evolving so rapidly that matching a monolithic query processor to each of them is infeasible. The EREQ project seeks to structure object query processors into well-defined software components that can be independently modified, extended and exchanged. This paper sets forth our initial ideas on what the major components will be and how we will specify the interfaces to each.

An Authorization Framework for Database Systems
Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...
متن کاملPath Query
DEFINITION Given a semi-structured data set D, a path query identifies nodes of interest by specifying the path lead to the nodes and the predicates associated with nodes along the path. The path is identified by specifying the labels of the nodes to be navigated and structural relationship (parent-child or ancestor-descendant) among the nodes. A predicate can be a path query itself, relative t...
متن کاملImprovement of diagnostic accuracy of Parkinson's disease on I-123-ioflupane single photon emission computed tomography (123I FP-CIT SPECT) using new Japanese normal database
Objective(s): I-123-ioflupane single photon emission computed tomography (FP-CIT-SPECT) has been used to assess dopamine transporter (DAT) loss in Parkinson's disease. The specific binding ratio (SBR), a quantitative parameter of DAT density in the striatum, may be affected by differences in age, sex, and SPECT system. The purpose of this study was to evaluate the util...

متن کاملRole of Heuristic Methods with variable Lengths In ANFIS Networks Optimum Design and Training
ANFIS systems have been much considered due to their acceptable performance in terms of creation of fuzzy classifier and training. One main challenge in designing an ANFIS system is to achieve an efficient method with high accuracy and appropriate interpreting capability. Undoubtedly, type and location of membership functions and the way an ANFIS network is trained are of considerable effect on...
