At that time was down sizing to an open system, the system had been replaced mainly the retail industry. There, the Oracle database system design done on Unix, the development of back-end data processing program, many of the problems was solved performance issue of RDBMS.Next, Windows NT came. On the Windows NT version 3.0 platform, I was performed "service" programming, "system / device driver (later WDM)" programming, COM (Active X) programming through versions 3.1 and 3.5, 3.51, 4.0 in various challenging experiences.Interest has shifted to the GUI desktop application, mainly development of IDE, development of CAD application, etc.In the world of front-end Web development I felt pain to be late, but I can say with confidence that the advantage in server side development has not been compromised.Currently I am earnestly acquiring GUI application development on iOS to be able to design and estimate with the same precision as "it" on Windows platform.

I was immersed in computer science. However, I also wanted to challenge other possibilities. The days when I was doing diving guides were shining, but I did not think that it will be longed forever. Although it was a good age, But I decided to return to computer science after all.

Personal computers were said to be "toys". However, there were people who understood the possibility of "toy" in the age of host computer. That is this era. I was absorbed in this industry.
