This research developed the MySQL Sandbox, a secured environment for processing SQL queries. It was implemented as a RESTful web service having three services - sandbox database creation, SQL statement processing and sandbox database resetting. It supports the simultaneous processing of multiple SQL statements from multiple users in multiple databases. It uses question identification (ID) and student...
The users need identity authentication before entering virtual lab and that needs to respectively set up users information management mechanism, this paper analyzes and designs uniform identity authentication and concentrating information management. Then, we analyze functional requirement of virtual laboratory platform, discusses uniform identity authentication module of virtual laboratory in detail...
The new technology supports new business scenarios or new implementations for the existing ones. The paper describes an implementation of B2B scenario. The Google cloud platform as service makes possible a digital broker system between businesses linked by interests. Architecture of this digital broker consists of common Cloud SQL database, hosted on Google platform, and a Google App Engine application...
Building Information Model (BIM) is an IT methodology to construct a facility virtually in details. The digital format representation is essential to facilitate information sharing and exchange among multiple contractors. Industry Foundation Classes (IFC) is utilized to embed the shared data in an XML standard structure to improve the interoperability among all interrelated participants within the...
Characterizing latent software faults is crucial to address dependability issues of current three-tier systems. A client should not have a misconception that a transaction succeeded, when in reality, it failed due to a silent error. We present a fault injection-based evaluation to characterize silent and non-silent software failures in a representative three-tier web service, one that mimics a day...
With the rapid development of the network scale and complexity, it is significant to find a new efficient and effective work of network management. This paper proposed a web-based distributed network management system which is implemented by J2EE platform. This architecture synthesizes the technologies such as Web, Ajax, Spring, JavaBean and so on to implement an open, scalable, heterogeneous, distributed...
A novel SQL Tunnelling system to allow communication with an SQL database is developed by utilising the standard Internet protocol HTTP. The communication with the database is allowed by a client interacting with a Web Service running on a standard off-the-shelf HTTP Server. With this tunnelling system, access to a database can be provided without providing access to the database native communication...
Online travel and ticket booking is one of the top E-Commerce industries. As they present a mix of products: flights, hotels, tickets, restaurants, activities and vacational packages, they rely on a wide range of technologies to support them: Javascript, AJAX, XML, B2B Web services, Caching, Search Algorithms and Affiliation; resulting in a very rich and heterogeneous workload. Moreover, visits to...
Recently more and more public biological pathway databases support at least one standard pathway format, e.g. PSI-MI, BioPAX and SBML, accessible from either FTP downloads or HTTP downloads. These standard pathway formats are machine readable and are often used for pathway integration and aggregation as well as visualization, analysis, but they are not well-suited for unassisted comprehension and...
Along with the proliferation of Web-delivered services and the wide adoption of popular Web technologies, it has been an emerging development style that composes services into Rich Internet Applications in the client-side runtimes, i.e. web browser. These service-oriented rich clients (SoRC) have to access and process client-side data for rich user experiences. Though server-side data access has become...
This paper describes an e-banking system designed for both mobile handhelds and regular computers. This system demonstrates how to bring together and generalize online services, such as e-banking, e-auctions and e-shopping. That is why the system exposes its services over HTTP in both HTML, targeting common web browsers, and XML (i.e. web services), targeting mainly, but not only, mobile devices....
With rapid development of urban construction, there are more and more urban construction archives, more and more types of construction archives. The traditional ways for submitting the urban construction archives, such as paper-based submission, disk-based submission and email-based submission, can't meet the much more complex demands. The shortage of paper-based way is that it can't be in time and...
The response of the traditional web is not so efficient that it can not satisfy the interface-friendly demand of the users because of huge amount data in distribution network management system and large access amount of the database. In order to adapt the requirements, this paper presents that web application framework combined the Ajax (asynchronous JavaScript and XML) and Web services is applied...
On the basis of analyzing the technical features of GWT, the integration principle of GWT and Berkeley DB Java Edition (BDJE) is researched firstly in this paper. Then a hierarchical and extensible solution of Network Teaching System (NTS) is put forwarded based on GWT. The experimental results show that the client-side of NTS is provided with widget by GWT based on Ajax, and the persistent data is...
Nowadays, alien species have become a threat to human existence and social sustainable development. An effective way to prevent them from spreading is Inspection and Quarantine. Focusing on this subject, we design and implement a digital integrated service platform which serves the Inspection and Quarantine Bureau. Based upon the web services, the system realizes information exchange and sharing of...
The public participation GIS for intelligent transportation plays an important role in urban transportation planning and decision-making. This paper presents an infrastructure for constructing the web based public participation GIS service for collecting intelligent transportation information. The system uses a multi-tiered J2EE architecture. The geographical interface is constructed by a java GIS...
The Web Service has been extended to the back-end database. In this paper, we propose a novel method of user behavior analysis in semantic network. We use the weight value to analyze and record user behavior and then check user behavior record with the signatures which are generated by the Intrusion Detection System (IDS). If a user record matches with signatures, the system will pass the record to...
