基于JSP的网络数据库连接技术

目前,数据库在Web服务中得到广泛应用。文中简要论述了网络数据库的三层结构及各层功能,对JSP技术进行了简单的论述。通过两个实例,详细论述了在JSP页面中利用JDBC API连接Access数据库和MySQL数据库的具体步骤及特点,证明了采用JDBC技术连接和操作各种数据库更加简便。     

Web页面两种模型对照研究

Web技术可实现Internet上跨平台超文本和超媒体的链接,使得信息查询和发布方便快捷,于是Web页面的相关技术有了深入的发展,出现了静态和动态两种页面模型。对这两种模型页面的模型及其原理、页面制作、信息（数据）传送方式、数据库的连接与访问技术等四个方面进行了对照研究。

基于JavaBean的数据库访问技术

介绍了JSP和JavaBean组件技术及在访问数据库工种机制,并给出实例介绍如何在JSP页面中利用JavaBean连接MySQL数据库.     

在ASP.NET中如何使用web.config文件配置数据库连接

开发网站时,经常要用到的操作就是数据库操作,在web.config文件中对连接数据库的代码进行配置是经常使用的操作,优点是当需要改变连接数据库的代码的时候,不用对每个页面中的连接数据库的代码进行修改,只修改web.config文件中的连接数据库的代码就可以了。

基于聚类分析的事件语义模式获取

为非结构化的Web页面标注事件语义信息,可以丰富Web页面结构化信息,加深对Web页面内容的理解。选取新闻类型的Web页面,遵照事件语义标注规范对选取的未标注Web页面进行事件语义标注。对标注了事件语义的语料实例进行抽象得到事件语义结构模式;利用层次聚类算法,将所得的事件语义结构模式进行聚类分析,得到不同类别的事件语义模式。实验结果表明,在已标注事件语义的语料实例的基础上,利用聚类算法进行分析,获取各种类别的事件语义模式,对Web页面内容分析与理解是非常必要的。     

性能测试

无论使用LAN连接还是调制解调器(Modem)连接方式,Netscape Navigator翻译HTML页面的速度都要比Internet Explorer快。在浏览一些实境(read-world)页面时,你能注意到这种差异。     

基于JDBC-ODBC的数据库访问方法的设计与实现

首先介绍了JDBC、ODBC以及JDBC-ODBC桥的相关概念,并阐明了JDBC-ODBC桥的新功能,然后分析了基于JDBC-ODBC连接数据库的原理,并用实例实现了数据库的连接。本文利用JavaBean将数据库的连接封装起来,当多个页面都需要连接数据库时,可以直接调用相应的Bean,使得开发高性能的数据库应用变得相对容易。     

基于WAMP的智能终端用户信息分析系统设计

本文提出一种智能终端上使用的用户信息收集系统。系统采用B/S结构,将从客户端浏览器收集到的用户信息回传服务器并利用图形化工具进行分析,根据分析结果显示出的用户上网习惯与喜好等对其进行分群,从而为进行群组化定向营销和广告推送提供可能。系统实现过程是首先架设WAMP服务器,然后设计数据库并编写服务器端PHP程序进行连接,同时编写客户端HTML5标准页面,最后进行PC、iPad和Android手机端的访问测试。本系统的特色在于服务器端页面对于多种智能终端不同屏幕大小的显示自适应。     

Assessing Ideational and Evaluative Skills and Creative Styles and Attitudes

This article describes the rationale for the multiphase creative problem solving process, and reports the findings from an empirical investigation conducted to facilitate the problem solving of managers. The ideational skills of the managers were assessed before and after training in a complete process of creative problem solving, along with their ideational attitudes, creative problem solving style (i.e., generator, conceptualizer, optimizer, or implementor), and evaluative skill (i.e., ability to recognize original ideas). The most important findings indicated that the training had a significant impact on the evaluative accuracy of the managers. They were significantly more accurate in their judgments about original ideas after training, both in their identification of original ideas and their recognition of unoriginal ideas. After training, the managers also gave more solutions and more original solutions to problems. Finally, several variables (e.g., the “preference for active divergence” attitude, and the conceptualizer process style) seemed to moderate the impact of training. Training was therefore effective, with specific effects that can be predicted from pre-training individual differences in attitudes and process style.

Rank and select revisited and extended

The deep connection between the Burrows–Wheeler transform (BWT) and the so-called rank and select data structures for symbol sequences is the basis of most successful approaches to compressed text indexing. Rank of a symbol at a given position equals the number of times the symbol appears in the corresponding prefix of the sequence. Select is the inverse, retrieving the positions of the symbol occurrences. It has been shown that improvements to rank/select algorithms, in combination with the BWT, turn into improved compressed text indexes.     

Semantics and verification of monitors and systems of monitors and processes

In this paper we present a sound and complete semantics for the monitor concept of C.A.R. Hoare. First a method for specification of monitors, introduced by O.-J. Dahl, is reviewed. This method is based on the relation between the historic sequence of monitor procedure calls and the historic sequence of monitor procedure exits. Based on such specifications and our new monitor semantics we present a method by which it is possible to prove that a concrete monitor is an implementation of an abstract one. In the last part of the paper an axiomatic semantics for systems of concurrent processes and monitors is introduced. The method supports verification by separation of concerns: Properties of the communication to and from each process are proven in isolation by a usual Hoare style axiomatic semantics, while abstract monitors are also specified in isolation by the method reviewed in the first part of the paper. These properties of the components of the system are then used in a new proof rule to conclude properties of the complete system. Stein Gjessing received a Ph.D. (actually a Dr. philos.) from the University of Oslo (Norway) in 1985. Presently he is an Associate Professor at the Institute of informatics, University of Oslo, Norway. Dr. Gjessings research interests are in the area of concurrent and distributed programming, operating systems, formal specification and verification and programming languages.
