This paper conducts an investigation in the domestic vehicle management standards and proposes an improved design of vehicle management system based on RFID technology. The system improves vehicle management systems in the domain of system security, data acquisition, statistical analysis, remote computer monitoring and hand-held card reader applications by integrating RFID technology with network...
By using the running control idea based on agile knowledge rules, the paper researches a general framework of agile scheduling decision support system (ASDSS), and also further researches the database system, the model base and method base in the ASDSS. The paper uses a hierarchical design way to design the database system, and proposes a vehicle optimization model VOM for the model base and a “dichotomic...
Many web databases can be seen as providing partial and overlapping information about entities in the world. To answer queries effectively, we need to integrate the information about the individual entities that are fragmented over multiple sources. At first blush this is just the inverse of traditional database normalization problem - rather than go from a universal relation to normalized tables,...
As the facts of the management in the freight forwarding agency enterprises nowadays, aiming at the "one document to the end" activities, we developed and realized the software of management information system for the freight forwarding agency business of mini-enterprise based on VB6.0. The system adopted the C/S (customer/server) and access database on the basis of the need of the export...
In this paper, the vehicle-track system of city track traffic is being studied as a whole. The links between tools used by different engineering disciplines in the city track traffic field is investigated. A database of tool shares been set up and is being used to establish links between tools and, more importantly, gaps where tools are not interfacing as they could. The structure of the database...
Recent developments in portable device and growing wireless communication networks have evolved embedded database during the last few years. The embedded database store data that technician and others can access to monitor, diagnose, and otherwise work with the machine. Based on vehicle management requirements, the characteristics and actual demand of remote supervisory system are analyzed in this...
Aiming at the deficiency of being difficult to investigating and analyzing the traffic data by the toll data of freeway, utilizing the information storage technology of PDF417 two-dimensional (PDF417-2D) bar code, this paper sets up an integrated system of freeway toll and traffic data investigation, makes the encoding rules and content of record information which on the PDF417-2D bar code, and presents...
With the advancement of their information technology, many enterprises have accumulated a large amount of business data. We hope to analyze these data on a higher level in order to use then better. The current database systems are unable to find the association rules in data, and cannot predict the developing trend and lack method mining information and knowledge hidden behind the data information...
A variety of Urban Rail Transit (URT) systems have been operating in Korea and they have different technology bases, causing a lot of difficulties in taking measures against trouble, training, upgrading, interoperability and so on. As such, a standardization project has been carried out to solve the problems by setting up the national standards for the systems. The main role of the project is to support...
Uncertain data are inherent in many important applications. Recently, considerable research efforts have been put into the field of managing uncertain data. In this paper, we summarize existing techniques to query and model uncertain data and systems that effectively manage uncertain data, mainly from a probabilistic point of view.
Large numbers of moving objects and continuous queries characterize moving object environments. Efficient evaluation of these queries in response to the movement of the objects is important for supporting acceptable response times. In such environments, the traditional approaches suffer from the need for frequent updates and thereby results in poor performance. In this paper we present a novel approach...
In this environment each mobile peer has a local database that stores and manages a collection of reports (where each report is a product record, or a coupon), and all the local databases maintained by the mobile peers form a mobile e-commerce (or, more generally, a mobile P2P) database. Queries on this database are posed by potential customers, and they search for coupons and products pertaining...
