Modern business applications predominantly rely on web technology, enabling software vendors to efficiently provide them as a service, removing some of the complexity of the traditional release and update process. To increasing web application accuracy and speed user process crawler model. Cutting edge business applications transcendently depend on web innovation, empowering programming sellers to give proficiently them as an administration, uprooting a portion of the multifaceted nature of the customary discharge and overhaul process. While this encourages shorter, more productive and successive discharge cycles, it obliges persistent testing. Having knowledge into application conduct through unequivocal models can to a great extent bolster improvement, testing and support. Model-based testing permits effective test creation taking into account a depiction of the states the application can be in and the moves between these states. As determining conduct models that are sufficiently exact to be executable by a test computerization device is a hard assignment, an option is to concentrate them from running applications.
现代商业应用程序主要依赖于web技术,使软件供应商能够有效地将其作为服务提供,从而消除了传统发布和更新过程的一些复杂性。以提高web应用程序的准确性和用户处理爬虫模型的速度。尖端的商业应用程序完全依赖于网络创新,使编程销售商能够像管理一样熟练地提供这些应用程序,从而在一定程度上消除了传统的开发和检修过程的多面性。虽然这鼓励更短,更高效和连续的放电周期,但它强制持续测试。通过明确的模型了解应用程序的行为可以在很大程度上加强改进、测试和支持。基于模型的测试允许有效地创建测试,同时考虑到应用程序可能处于的状态的描述以及这些状态之间的移动。由于确定足够精确的行为模型以由测试计算机化设备执行是一项困难的任务,一种选择是将它们从运行的应用程序中集中起来。

A Survey on Various Online Payment and Billing Techniques 关于各种在线支付和计费技术的调查
Pub Date : 1900-01-01 DOI: 10.34293/sijash.v7i3.1374

Over the past few decades, Internet technology has shaped almost everybody's life. Business banks set up internet workstations and provide customer information requirements, internet payment fund diversion financial services, credit, investment, etc. An online payment system is a means for conducting economic transactions based on the Internet.This allows a seller to accept payments over the web or other internet connections, such as direct network connections between retail stores and their suppliers— a common way of keeping inventories just in time. Online payment systems are greatly expanding a company's scope and selling potential.Usually, online payment services are operated by third-party firms like PayPal, Google or Click2Pay. Such companies make a profit by taking a small portion of each transaction, or by signing contracts with institutions that require a large number of transactions. Without the ability to make online payments, a large Internet retailer, like Amazon.com, could not exist. Online payment systems have expanded the playing field between big and small companies, as each of them can adopt the same payment methods when they sign up with third party payment processors.
在过去的几十年里,互联网技术几乎改变了每个人的生活。商业银行设立互联网工作站,提供客户信息需求、互联网支付资金分流、金融服务、信贷、投资等。在线支付系统是一种基于互联网进行经济交易的手段。这允许卖家通过网络或其他互联网连接接受付款,例如零售商店与其供应商之间的直接网络连接——这是一种及时保持库存的常用方法。在线支付系统极大地扩展了公司的业务范围和销售潜力。通常,在线支付服务由第三方公司运营,如贝宝、谷歌或Click2Pay。这些公司通过从每笔交易中抽取一小部分,或者与需要大量交易的机构签订合同来盈利。如果没有在线支付的能力,像亚马逊这样的大型互联网零售商就不可能存在。在线支付系统扩大了大公司和小公司之间的竞争环境,因为每个公司在与第三方支付处理器签约时都可以采用相同的支付方式。

Data Mining Concepts and Techniques 数据挖掘的概念和技术
Pub Date : 1900-01-01 DOI: 10.5860/choice.49-3305

Understand the need for analyses of large, complex, information-rich data sets. Identify the goals and primary tasks of the data-mining process. Describe the roots of data-mining technology. Recognize the iterative character of a data-mining process and specify its basic steps. Explain the influence of data quality on a data-mining process. Establish the relation between data warehousing and data mining. Data mining is an iterative process within which progress is defined by discovery, through either automatic or manual methods. Data mining is most useful in an exploratory analysis scenario in which there are no predetermined notions about what will constitute an "interesting" outcome. Data mining is the search for new, valuable, and nontrivial information in large volumes of data. It is a cooperative effort of humans and computers. Best results are achieved by balancing the knowledge of human experts in describing problems and goals with the search capabilities of computers. In practice, the two primary goals of data mining tend to be prediction and description. Prediction involves using some variables or fields in the data set to predict unknown or future values of other variables of interest. Description, on the other hand, focuses on finding patterns describing the data that can be interpreted by humans. Therefore, it is possible to put data-mining activities into one of two categories: Predictive data mining, which produces the model of the system described by the given data set, or Descriptive data mining, which produces new, nontrivial information based on the available data set.
了解对大型、复杂、信息丰富的数据集进行分析的需求。确定数据挖掘过程的目标和主要任务。描述数据挖掘技术的根源。认识到数据挖掘过程的迭代特征,并指定其基本步骤。解释数据质量对数据挖掘过程的影响。建立数据仓库和数据挖掘之间的关系。数据挖掘是一个迭代过程,在这个过程中,通过自动或手动方法,进度由发现来定义。数据挖掘在探索性分析场景中最有用,在这种场景中,对于什么将构成“有趣”的结果没有预先确定的概念。数据挖掘是在大量数据中搜索新的、有价值的和重要的信息。这是人类和计算机共同努力的结果。通过平衡人类专家在描述问题和目标方面的知识与计算机的搜索能力,可以获得最佳结果。在实践中,数据挖掘的两个主要目标往往是预测和描述。预测包括使用数据集中的一些变量或字段来预测其他感兴趣的变量的未知值或未来值。另一方面,描述侧重于寻找描述可由人类解释的数据的模式。因此,可以将数据挖掘活动分为两类:预测性数据挖掘,它产生由给定数据集描述的系统模型;描述性数据挖掘,它产生基于可用数据集的新的、重要的信息。
