데이터 웨어하우징(Data Warehousing, DW) 개념이 탄생한 1970년대는 미국 유통 대기업 월마트가 폭증한 데이터베이스를 좀 더 효율적으로 보고자 했던 시기와 맞닿아 있다. 그러나 지금까지 월마트의 데이터 관리에 관한 논의는 대부분 생산관리, 재고관리 등 운영 측면이 강조되어 왔고 데이터 자체에 대한 관심은 상대적으로 적었다고 할 수 있다. 본 연구는 데이터베이스에 관한 기술적인 개념을 먼저 아우른 뒤 월마트의 데이터 웨어하우징 프로젝트 사례를 구축 전(준비)-구축(실행)-구축 후(평가) 단계로 나누어 분석하였다. 본 연구는 월마트가 데이터 웨어하우징을 진행하면서 조직에서 지속적으로 발생하는 문제를 어떻게 해결하였는지, 그리고 데이터 관리를 통해 어떻게 전사적인 공헌을 이룩하였는지에 초점이 맞추어져 있다. 산업을 막론하고 전 세계적으로 가장 큰 데이터베이스를 가지고 있는 월마트의 사례를 현재의 관점에서 다시 살펴봄으로써 최근 재조명되고 있는 (빅)데이터 이슈와도 연결점을 찾을 수 있을 것이라 기대한다.

Purpose - Our Research is a study on the competition structure between retailers in traditional markets. Specifically, this study examined the effects of SSM, commodity supply store, Hanaro mart, food mart and other mart in traditional markets on retail stores of small businesses. The purpose of this study is to provide a solution to the market encroachment of large retailers in traditional markets. Research design, data, and methodology - This study is based on the data of 'Market Survey of Traditional Market·Shopping Mall and Store Management in 2016' and 'Current status of SSM(Super SuperMarket), commodity supply store, Hanaro mart, food mart and other mart in the traditional market in 2017' conducted by Small Enterprise and Market Service. In this study, a multiple regression equation was constructed using the number of SSM, commodity supply store, Hanaro mart, food mart and other mart as an independent variable and sales, number of customers as a dependent variable for analysis. Results - The increase of SSM and commodity supply stores in the traditional market affects the sales decrease of the surrounding small merchants in the traditional market. This means that the SSM and commodity supply stores can lead to the decline of the traditional market. However, it has been found that the penetration of these companies in traditional markets does not affect the number of visitors. Second, Hanaro mart's entry into the traditional market has a negative impact on the sales and visitor numbers of the surrounding small-scale merchants. The increase in the number of food mart has a significant effect on the sales and the number of visitors to the small stores. The results of this study indicate that the food mart can contribute to the revitalization of traditional markets. Lastly, other mart with more than medium size were found to affect the sales of small stores, the number of visitors. Conclusions - We examines the competitive structure among retailers in traditional markets. The penetration of large retailers in traditional markets has a negative impact on traditional markets, particularly Hanaro mart has a greater impact than SSM. We provide practical and theoretical implications for the retail competition structure in traditional markets.

Purpose - In general, large companies have larger organizations, funds, and systems to provide more effective and efficient services in the market. However, development needs to support the livelihood of ordinary citizens who work for small businesses as well. This research suggests that a new distribution channel, called a "foothold style Kosa mart," that cooperates jointly with a distribution center and a large discount mart can provide direct solutions to small and mid-size distributors. This new distribution channel can achieve a limited type of "Nadle shop (small supermarket) foster project" related to building a joint distribution center and improvement in wholesale supply. Research design, data, and methodology - Data about the Korea distribution situation, the Nadle stores, and the logistics centers were collected from literature, Statistics Korea, journals, and reports. Specifically, we investigated information about Kosa Mart and Nadle stores. We focused on the redesign of the distribution center for the Nadle store. Results - The Kosa Mart distribution center now includes 18 warehouses, and has been handling 2000-3000 items. Most of the warehouses have been simply designed and items loaded and stored without refrigeration; thus, it is possible to store only products of certain manufactured goods. The current logistics center has no wholesale function because it failed to resolve the joint purchasing and product supply issues of competitively priced products. Conclusions - This study aimed to identify ways to strengthen the competitiveness of small- and medium-sized retailers. A Kosa Mart redesign aims to unifying the logistics center, stores, and customers. First, the joint wholesale logistics system, equipped with an integrated ordering system, needs to process customer orders and store orders at the same time. Second, excellent small business product development has to connect with production. Third, the store composition needs to support a shipping hub. Fourth, the Mart differentiates itself from convenience store goods by supplying regional and specialized products to customers. Fifth, a service buying agent and direct transactions between producers and consumers need to be established, and exhibits and displays of goods need to be improved.

Purpose - This study aimed to analyze the strategy of late domestic entrants into the Chinese retail market, focusing on the case of Lotte-Mart, given that there are few studies on market entry strategies of domestic retail companies in China. Research Design, data, methodology - The methodology of this paper is a case study approach, focusing on literature reviews and a few interviews. We conducted a survey by disseminating questionnaires and conducting interviews focusing on the Chinese retail market, and analyzed Lotte-Mart's market entry strategy in China. Results - Lotte-Mart chose M&A as the mode of entry, pursuing quick market entry and rapid expansion. It chose small to medium size cities with relatively less competition. Subsequently, Lotte-Mart devoted significant effort towards localization, attempting to organize stores and assorting products to fit the Chinese consumers' preferences. It operated CSR programs to increase its brand awareness and to create a favorable brand image. Conclusions - Lotte-Mart now needs to devise alternative corporate strategies for business expansion and growth. An understanding of the Chinese retail market and the case study analysis of Lotte-Mart's market entry strategy offers significant insights for domestic retail companies looking to expand into China.

This study is to explore the airline network patterns of Incheon and Narita International Airports using passenger flight departure and arrival data of the two airports. The so-called Origin-Destination data is collected from the airports' websites and some of the important data items are flight number, city of origin, destination city, departure/arrival time, number of flights, and delay time. A snowflake schema dimensional model is proposed and implemented. Tableau Public, a well-known visual analytic tool, is used to connect the dimensional model and played an important role in navigating the data space to find interesting and visual patterns among corresponding airports and airlines. For the efficiency of analyzing this spacious data mart, data visualization method was used. Four types of visualization method proposed by Yau was used; visualizing patterns over time, visualizing proportions, visualizing relationships, and visualizing spatial relationships. The strength of connectivity of each flight segments is calculated to evaluate the degree of globalization of Seoul and Tokyo. We anticipate that various patterns and new findings produced by the data mart would provide airline managers, airport authorities, and policy makers in the field of travel and transportation with insightful information.
