The book of "Odakyu diagram table in 2016" arrives a little time ago, I ordered yesterday.

I need the basic data and parameters for my train diagram simulator I told you yesterday.

At any rate, I think,

If the data of the diagram data has been opened on the Web site, it will help me very well absolutely.

On the other hand, I also think that it cannot be helped.

-----

Firstly, the train diagram is very valuable data, so some people can buy the data for a high price.

Secondly, few people wants to use the data for their own interest only. (It might be me only, I think)

Finally, if the data like the above, becomes opened, I am afraid that a lot of annoyed troubles will happen (some armatures claims the design of diagram, or abused by terrorist)

I think that train diagram data is one of the typical "big data", so called.

The one of the reasons I always say "Big data, it must die" is

"there are a lot of idiots who want to talk about "big data business", even they don't know it is very hard to get the "big data". It is really a rare case.
