Reconstruction of Large Systems Based on Business Data Model Reconstruction of Large Systems Based on Business Data Model V Shoichi Okugawa (Manuscript received March 28, 2006) Some of our customers have large mainframe systems that have become oversized and hard to maintain, and these customers now want to structurally reform these sys- tems. However, it has been difficult for them to learn how to make this reform. This situation prompted Fujitsu to develop the FUTURITY solution, which is based on the experience we gained in the structural reform of KDDI Corp.’s system and involves work processes, development methodologies, and tools. FUTURITY is composed of four solutions: FUTURITY-TB, which is used to abstract a customer’s business into a business data model and develop To-Be data models; FUTURITY-AI, which is used to abstract the data structure of a customer’s current system and develop As-Is data models; FUTURITY-MP, which is used to compare To-Be data models with As-Is data models and develop reconstruction plans; and FUTURITY-SI, which provides methods and tools for efficiently developing a system designed on the basis of business mod- els. This paper describes the basic system development philosophy and other details of FUTURITY. 1.

  • Fujitsu's Approaches to Developing Smartphones
    Fujitsu’s Approaches to Developing Smartphones Katsumi Takada Amid a paradigm shift from feature phones to smartphones, Fujitsu acquired the top market share in Japan as a vendor of mobile phones with its quick deployment of 11 smartphones for NTT DOCOMO, INC. and KDDI CORPORATION in 2011. While maintaining this strong domestic market position, Fujitsu is aiming to enter global markets in earnest with Raku-Raku SMART PHONEs in 2012. Fujitsu smartphones are founded on two of the company’s strengths. The first is the company’s technologies—its phones have the best features in the industry because they adopt the latest and fastest platform, they have leading radio technology, and they use Fujitsu’s unique technologies that it has cultivated so far, such as human perception technolo- gies for good visibility of displays, good audibility of phone calls, and comfortable touchscreen controls. The other is the company’s excellence in manufacturing within factories that are lo- cated in Japan. Furthermore, Fujitsu keeps improving its software development ability to use open-source technology which is necessary for smartphone platforms such as Android OS. This paper introduces Fujitsu’s smartphone strategy that utilizes these strengths and also its ap- proach to developing new markets. 1.

The dedication ceremony for IEEE milestone was held on December 18, 2019 at Empire Hotel Tokyo. Dr. Toshio Fukuda, IEEE President-Elect, Professor of Meijo University, presented the plaque to Dr. Hirotaka Hara, CEO and Representative Director of Fujitsu Laboratories Ltd. The HEMT was the 35th IEEE milestone in Japan. Achievement on the plaque is as follows. ・High Electron Mobility Transistor, HEMT, 1979 “The HEMT, invented in 1979, was the first transistor to incorporate an interface between two semiconductor materials with different energy gaps. HEMT proved superior to previous transistor technologies due to high mobility of channel carriers, resulting in high speed and high frequency performance. HEMTs have been widely used in radio telescopes, satellite broadcasting receivers and cellular base stations, giving rise to a fundamental technology supporting the information and communication society.” A presentation ceremony hosted by IEEE Tokyo Section was held at Hikari-no-ma, Imperial Hotel Tokyo. There were 66 attendees. The master of ceremonies was D r. Yasuhiro Takishima, Secretary of IEEE Tokyo Section, Executive Director of KDDI Research, Inc. First on the agenda, Dr. Hideyuki Tokuda, Chair of IEEE Tokyo Section, President of National Institute of Information and Communications Technology, gave a speech as an organizer, followed by Dr. Toshio Fukuda.
