DATAVERSITY™ recently interviewed Yoshihiko Hoshi, a Data Architect at Hitachi Solutions East Japan. Yoshihiko will be giving a session at the Enterprise Data World 2014 Conference in Austin, Texas from April 27 – May 1, 2014. His session is titled “Implementing Theoretical Data Warehouse Model in Real Business Field – A Case Study: Practical Approach of Data Warehousing” and will be co-presented with Hiroshi Yagishita, a System Modeler at Future Modeling Technologies.

The Speaker Spotlight Column (and its parallel venture the Sponsor Spotlight Column) is an ongoing project that focuses on highlighting several of the central issues represented at the many Data Management conferences produced by DATAVERSITY.

The primary emphasis of the interview was to question Yoshihiko on his work and history within the industry, with particular importance on his presentation at the upcoming conference:

DATAVERSITY (DV): What are you going to discuss during your session at EDW14, and what will the audience gain from attending your talk? (Please be specific about one or two issues you’ll be addressing and the benefits the audience will obtain).

Yoshihiko Hoshi (YH):

  1. The importance of ODS (Operational Data Store). ODS is the key success component for Data Warehousing.
  2. The effectiveness of SCD (Slowly Changing Dimension).  To grasp the lineage of slowly changing data, it’s very important to maintain ODS in daily operation.

I think the necessity of the ODS is not yet so popular. The audience will realize the value and validity of ODS and SCD.

DV: What is really important about such a topic in terms of the current state of Data Management and / or how the industry going to transform moving into the future?

YH: Whatever the future technology will change, the basic concepts and methodologies will not so dramatically change. So we need to grasp the core concept of those methodologies.

DV: Please tell us a little about yourself and your history in the industry, past work experience, and how you got started in the data profession?

YH: I am born to be a data modeler. I experienced various kinds of application developments over several industries and many businesses. Then finally I realized data is the core asset of any enterprises. So I started this data profession.

DV: What is the biggest challenge happening in your particular area of Data Management at this time?

YH: How we address our business not to stray off our customers’ core competence in such vogue movement like “Big Data”.

DV: How is such a change influencing your job?

YH: Although various new tools or technologies are emerging, I believe conceptual modeling is not so easily changeable. So it is very important that we never lose the mission, vision and goals of enterprises, and lead the enterprises’ conceptual model technologically independent and construct the firm data model as an infrastructure of the enterprises.

DV: How have your job, and / or the work you are doing at your organization, altered in the past 12 months? How do you expect it will change in the next 1-2 years?

YH: Nevertheless we must handle huge volume of data hereafter; we must catch up the technology as soon as possible.

DV: Are there any other emerging technologies you predict will affect your job function in the future?

YH: I think Artificial Intelligence technologies like deep machine learning etc. will penetrate into our business area. Data analytics will be affected dramatically.

DV: What’s your favorite “Data” or “Data Management” quote?

YH: “Before normalizing data, normalize your business.”

DV: How do you explain what you do for work, at a cocktail party, or to your grandparents?

YH: I’m playing building blocks of data.
