Practices of Using Blockchain Technology in ICT under the Digitalization of the World Economy

Abstract. Pursuing the purpose of effective functioning in today's conditions, the business is forced to transform rapidly, to modernize at all levels. The world is changing, erasing the limits of its certainty. Companies need quality transformations and strategies that are effective in the face of rapid change towards "deep" digitization. Massive corporate management systems increasingly need the flexibility to keep pace with change. And companies with an innovative culture are more in need of creative tasks than implementing detailed regulations. In the post-industrial time of digital economy, issues related to the development of the information sphere, the media and communications, the usage of modern information systems to develop the economy and stabilize social development as a whole, come first. The basic principles of practical application of Blockchain are investigated in the work. The stages of development of Blockchain technology, the stages of development of Blockchain technologies by time, the application of distributed registry technology in Blockchain applications, the principles of construction and operation of Blockchain have been specified. The benefits of using NEM for business are substantiated and the components of Proxima X technology, protocols and service layers, on-line and off-line protocols, decentralized applications are exposed

Electronic Commerce on Business Application

For some time now, Whole size business enterprises have used electronic commerce to conduct their business activities. The On-Line store is one of a number of popular web applications. This thesis focuses on one of the emerging On-Line store technologies which is known as Server-Side Java Application. In early 1960, private networks were dedicated for the use of electronic data interchange (EDI) and electronic funds transfer (EFT) in banking business. Recently, however, with the increased awareness and popularity of the Internet, electronic commerce has come to encompass individual consumers as well as businesses of all size. For most people, electronic commerce is defined as the buying and selling of products and services over the Internet, but there are many more aspects. We will discuss different definitions of electronic commerce in this paper. The most popular Web applications are the On-Line Stores. Most of such applications involve functions as searching for product information, ordering products, paying for goods and services, and for providing online customer service. A Web server, running continuously, accepts user’s connection; gets user requests and forward requests to business procedure; retrieves data (answers to user requests) from business procedure and sends it back to the user. An on-line store system is different from a traditional web publishing. It needs a customer’s interactive communication and frequent data update. The traditional HTML page does not satisfy the customer’s needs because all it does is simply publish static contents. More complex technologies are required in order to produce dynamic contents. There are a few technologies that can be used for implementing the on-line stores. Common Gateway Interface (CGI), Microsoft Active Server Page (ASP) and Serverside Java application are the most popular technologies. Introducing the Server-Side Java application is one of the latest and most exciting trends in Java programming. The Server-side Java application has many advantages over the other technologies

A Case Study of Software Product Line for Business Applications Changeability Prediction

The changeability, a sub-characteristic of maintainability, refers to the level of effort which is required to do modifications to a software product line (SPL) application component. Assuming dependencies between SPL application components and reference architecture implementation (a platform), this paper empirically investigates the relationship between 7 design metrics and changeability of 46 server components of a product line for business applications. In addition, we investigated the usefulness of Platform Responsibility (PR) metric as an indicator of product line component changeability. The results show that most of the design metrics are strongly related to the changeability of server component and also indicate statistically significant correlation between Maintainability Index (MI) and PR metric. The assessment is based on a case study of the implementation of the product line for business applications in a financial institution. The results show that PR metric can be used as good predictor of changeability in the software product line environment

XWeB: the XML Warehouse Benchmark

With the emergence of XML as a standard for representing business data, new decision support applications are being developed. These XML data warehouses aim at supporting On-Line Analytical Processing (OLAP) operations that manipulate irregular XML data. To ensure feasibility of these new tools, important performance issues must be addressed. Performance is customarily assessed with the help of benchmarks. However, decision support benchmarks do not currently support XML features. In this paper, we introduce the XML Warehouse Benchmark (XWeB), which aims at filling this gap. XWeB derives from the relational decision support benchmark TPC-H. It is mainly composed of a test data warehouse that is based on a unified reference model for XML warehouses and that features XML-specific structures, and its associate XQuery decision support workload. XWeB's usage is illustrated by experiments on several XML database management systems

On-Line Analytical Processing Accounting: Potentials, Application, and Design Methodology

Most software vendors and business consultants agree that On-Line Analytical Processing (OLAP) tools are needed to derive useful decision support from accounting transaction data. But business solutions can not be created just by installing and integrating some tool(s). To support a selection from the growing number of tools, potentials and applications of OLAP for accounting must be clarified. Moreover, a methodology for designing OLAP applications is needed. Being aware that all research in this brand-new field is still in progress, we address these problems in this paper

Merging an e-Business Solution Framework with CIS Curriculum

Since corporations first started conducting business on the Internet in 1993, it has moved quickly from being a curious spectacle to a matter of survival for most businesses. To achieve successful results in this on-line business environment on a consistent basis, companies need to rely on two critical success factors. First, a robust framework to guide the design and implementation of e-Business strategy is crucial. Second, if companies are interested in e-Business applications that are robust, flexible, scalable, maintainable, and platform-independent then the development environment used to design, implement, and deploy such applications is more critical than ever before. These characteristics will gain importance as corporations begin migrating e-Business applications from the traditional Web-based environment to a wireless, mobile, hand-held, and pervasive computing paradigm. A consequence of such ongoing changes in the information technology field will require Computer Information Systems (CIS) departments to regularly update curriculum to ensure that students are imparted with the conceptual knowledge and technical skills expected by the IT industry. This paper describes an e-Business solution framework, and analyzes the impact of the technological and e-business evolution on an existing CIS curriculum in the College of Business at a university in the state of Texas. It discusses the new curriculum developed and implemented in response to these technology changes. Finally, the paper also describes some of the challenges of implementing the new model and the resultant impact

Unified Approach in the DSS Development Process

The structure of today's decision support environment become very complex due to new generation of Business Intelligence applications and technologies like Data Warehouse, OLAP (On Line Analytical Processing) and Data Mining. In this respect DSS development process are not simple and needs an adequate methodology or framework able to manage different tools and platforms to achieve manager's requirements. The DSS development process must be view like a unified and iterative set of activities and operations. The new techniques based on Unified Process (UP) methodology and UML (Unified Modeling Language) it seems to be appropriate for DSS development using prototyping and RAD (Rapid Application Development) techniques. In this paper we present a conceptual framework for development and integrate Decision Support Systems using Unified Process Methodology and UML.Decision Support Systems, Unified Process, UML, Prototyping, DSS Tools

Using A Web-Based Supply Chain Management Simulation As An Experiential Learning Tool Across The Business Curriculum

A web based version of the common “Beer Distribution Game” that facilitates experiential learning was developed and tested for use across the business curriculum. While the fundamental elements of the original paper based game were preserved, the web-based on-line multiplayer version offers refinements to game play, administration and debriefing that allow more focus on the learning experience and open possible applications beyond the traditional one-time demonstration of the bullwhip effect. The web-based supply chain management simulation was tested and refined in Strategic Management courses and Integrated Business Curriculum courses at two widely separated universities. Students responded favorably to the on-line simulation and were very willing to reflect on what they learned about how they made decisions, how worked under conditions of uncertainty, how they treated information and how they worked in the supply chain environment. The simulation can be used to demonstrate systems thinking and various other concepts throughout the business school curriculum including courses in Operations Management, Strategy, Information Systems, and Marketing
