刚开始的时候一个非常简单的基于LAMP网站(Linux+Apache+MySQL+PHP).LAMP是开源的技术,建站速度快,开发成本低.要做的是装修O2O,业务特点是线下业务复杂、流程长、变化快,业务和产品都需要不断试错,技术要快速支撑.简单去看,架构主要分成3层:代理层、Web层和数据层.代理层主要做的是负载均衡,Web层负责对请求进行处理交给PHP进行页面渲染,PHP做了数据访问、业务逻辑和页面展现3件事.数据层也做一些数据库高可用.比如MySQL的双master多slave的架构,运维成本非常高.  相似文献

Analysis of interactivity in Web sites is an important extension of a long tradition of analyzing content of media messages. But both interactivity and online analysis of content and features offer unique challenges to researchers. This study develops and tests a tool for measuring interactivity in the context of health‐related Web sites. The tool was flexible enough to distinguish among multiple types of interactivity and powerful enough to show differences in interactivity based on domain type. Thus, it should have a relatively long life as a multifaceted tool for the tough job of measuring interactivity online.  相似文献

We developed an interdisciplinary model to examine how online consumers' perceived interactivity, perceived Web assurance and disposition to trust affect their initial online trust. Perceived interactivity is theorized as an interpersonal‐based antecedent, disposition to trust as a personality‐based antecedent, and perceived Web assurance as an institution‐based antecedent to initial online trust. Results indicate that both consumers' perceived interactivity and perceived Web assurance positively influence their initial online trust. Therefore, it is of importance that e‐vendors make efforts to enhance online consumers' perceived interactivity of their Web sites as well as addressing consumers' major trust concerns by adopting third‐party Web assurance seals.  相似文献

There are indications that interactivity could benefit the effectiveness of mobile advertisements. But there are few guidelines on how to design interactive mobile advertisements. This study investigated the influences of various design features of mobile advertisements on perceived interactivity and the relationship between perceived interactivity and attitude toward mobile advertisements. An experiment consisting of 2 sessions was conducted to test 5 proposed hypotheses with 40 participants. Results showed that the number of user control options and the customizability of advertisements have significant influences on users' perception of interactivity. The more options a message advertisement provides, the more interactive the participants perceive the advertisement; a customizable game advertisement is perceived as more interactive than an uncustomizable game advertisement. But no significant effects of presenting instructional information of mobile Web advertisements and including humorous elements were found. Finally, perceived interactivity was found a strong predictor of attitude toward mobile advertisement.  相似文献

Two major attributes influence a project aimed at developing educational software: user interactivity and graphic design. These two attributes are not easily found within the same development tool. Moreover, sometimes the development tool is either very expensive to acquire or too difficult to use. This article aims to present a solution to the creation of educational development tools which emphasize the conjunction between interactivity and graphic design. The authors propose a methodology based on Web technology and an association between the Java programming language and the authoring tool Flash. In addition to fostering interactivity, Java offers development packages at no cost. The authoring software Flash is inexpensive and allows the creation of finely crafted Web pages with graphic animations and sound editing. This article describes the methodology that enables the association between Java and Flash components. This methodology was conceived during the development of a structural analysis educational software product specially geared to undergraduate engineering students. In order to ensure the understanding of our proposal, a specific example was created, along with sample pages that illustrate this methodology.  相似文献

The emergence of Web 2.0 technology provides more opportunities to foster online communication and sharing in an e-learning environment. The purpose of this study was to develop a Web 2.0 annotation system, MyNote, based on the Web 2.0 core concepts which emphasize ease of access and active sharing and then to gain an understanding about people’s perceptions of MyNote from a usability perspective. MyNote was employed on multimedia learning objects in a Learning Management System (LMS), and out of the LMS as well in this study. The evaluation results showed that, with factor analysis, interactivity, usefulness, helpfulness, and willingness for future use were categorized to represent the perceptions of MyNote. It was also found that the factors of interactivity and helpfulness were statistically significant to predict the future use of MyNote. Lastly, the habit of taking notes also affected learners’ perceptions of using MyNote.  相似文献

A steadily growing trend in Web applications is the development of user interfaces through rich Internet applications. Among other capabilities, RIAs offer high interactivity and native multimedia support, giving them a major advantage over standard HTML To update existing HTML Web applications, the authors propose the RUX-Model, which facilitates the user interface adaptation of existing Web 1.0 applications to Web 2.0. Their proposal focuses on new RIA capacities that exploit the data and business logic already provided in legacy Web models.  相似文献

The phenomenal interest and growth of the World Wide Web as an application server has pushed the Web model to its limits. Specifically, the Web offers limited interactivity and versatility as a platform for networked applications. One major challenge for the HCI community is to determine how to improve the human-computer interface for Web-based applications. This paper focuses on a significant Web deficiency — supporting truly interactive and dynamic form-based input. We propose a well-worked form interaction abstraction that alleviates this Web deficiency. We describe how the abstraction is seamlessly integrated into the Web framework by leveraging on the virtues of the Web and fitting within the interaction and usage model of the Web.  相似文献
