Tableau: Tell us more about DARTSLIVE. Mr. Tomoyuki Okawa, General Manager, Business Analysis Department, Corporate Planning Division: DARTSLIVE performs planning, manufacturing, and sales for online dart machines, and places them at a number of shops and dart bars. We also perform business by focusing on darts such as event planning and conducting, and management for dart bars, etc. Tableau: What kinds of data do you work with? Mr. Okawa: Millions of play results in dart games are coming in per day. We utilize Tableau by storing the data as raw data, and aggregating and re-using it by using the data warehouse for easy analysis, then, putting it in Tableau. The data is stored in the relational database, and a data warehouse is used in order to analyze the data. One of them, Yahoo! Big Data Insight, is used to store service data, sales data, and the related promotion data, etc. Then, the multiple data are divided from there and re-combined on Tableau with the data placed in a columnar-type database. Tableau: Was there a particular problem you were facing? Mr. Okawa: Absolutely, the files collecting the data were scattered around, and it was totally difficult to pull them together. Therefore, we try to solve the problems by using Tableau Online at the same time in order to collect the files of Tableau in one place. Tableau: What are the most important benefits of Tableau Online? Mr. Okawa: One of the major reasons for adopting Tableau Online is that the server and the infrastructure are provided without our preparation. I was also very attracted to being able to start from one license. Since it is easy to start it without significant costs, promoting this introduction is a big benefit now by decreasing the personnel cost in the infrastructure area and the in-house cost.
