Integrity constraints in the information source tracking method 总被引:1,自引:0,他引:1
We study the issue of integrity constraints in the Information Source Tracking (IST) method. The IST method is an approach to the management of uncertain data in database systems. The main idea behind IST is that database information is supplied, or confirmed, by information sources. The accuracy of data is modeled by the reliability of the contributing information sources. In practice, information sources that are generally quite reliable may supply conflicting data at times. A database system based on IST must accept such data, and be capable of functioning correctly despite the inconsistency. We concentrate on cases where conflicting data is in violation of “key constraints”, a special form of functional dependencies resulting from the imposition of a key for each relation in the database. We present an approach, based on the adjustment of conflicting information source reliabilities, to handle data in violation of key constraints 相似文献

Input Shaping Technique (IST) and Time Delay Control (TDC), a robust feedback control law, were combined to achieve fast and precise point-to-point motion of a chip mounter. TDC was used as a feedback control to overcome disturbances and parameter variations, an IST was used to suppress the residual vibration induced in the closed loop system. TDC was designed first for the machine, and a discrete version of IST was designed on the basis of the closed-loop dynamics. In the design of TDC, a better set of gains was available thanks to the use of IST than TDC alone; in the design of IST, too, a better design was possible than IST alone. As the result of the concurrent design and synergy of the two methods, point-to-point motion could be achieved with no overshoot, the settling time of about 0.05 s and few steady-state errors to position commands of 1.5 mm. This result is far better than a conventional PID control or TDC alone could achieve, thereby showing the effectiveness of the concurrent design. 相似文献

This paper presents a study of the Portuguese financial sector during the period 1994–1999. The research, based on previous studies about the productivity paradox of information systems and technology (IST) investments, examines the ‘services sector’ and includes the ‘human subsystem’ of an organisation, clients and employees, as variables of analysis. The conclusion from this research indicates a complementary effect (not substitution effect) between IST and labour, the strategic impact of IST in several organisation areas, and the need to design new functions, other than the traditional Cobb‐Douglas function, to evaluate the impact of IST on organisations. 相似文献

Information source tracking method: efficiency issues 总被引:1,自引:0,他引:1
This paper is devoted to the study and analysis of query processing efficiency in the information source tracking (IST) technique, an approach to the representation and manipulation of uncertain and inaccurate data. We show that the efficiency depends on the average number of information sources confirming the same data in the database. If this number is close to unity, then the efficiency of query processing for the IST model is comparable to conventional relational database systems. For the case where multiple information sources confirm the same data in the database, we present a variation of IST, called the Dual IST method, which provides efficient query processing. Extended relational algebra operations are presented for Dual IST, and proven to be correct under the “alternate worlds” semantics interpretation. The complexity of reliability calculation in IST and Dual IST methods is also studied 相似文献
