Patent number: 11138173Abstract: A table relation analysis assisting apparatus analyzes a relation between pieces of data in a certain column (external key) astride tables in a relational database. The apparatus analyzes a relation between tables and holds inter-table relation analysis information in which tables, pieces of data in the tables being in a one to one relation or a plural to one relation, are defined as one table group. In the apparatus, an analysis result display unit provides a display in such a form that one or more tables in a relational database are contracted into a table group. The display unit displays table groups in such a form that which of a one to one relation or a plural to one relation a relation between pieces of data included therein is astride tables can be viewed.Type: GrantFiled: September 12, 2018Date of Patent: October 5, 2021Assignee: HITACHI, LTD.Inventors: Yasunari Takai, Keishi Ooshima, Katsumi Kawai, Makoto Kimura, Kiyoshi Yamaguchi

Publication number: 20170140309Abstract: An attribute having influence on a business flow is automatically extracted among one or more attributes associated with the business flow when the business flow is restored based on history data of business performed on a business system. An event sequence variation indicating an order of an attribute name is calculated based on a chronological relation of an attribute value of a date and time from history data of the business configured with an attribute name and an attribute value of business, the number of appearances of each attribute value of each attribute other than a date and time is counted for each event sequence variation, event sequences that are similar in a distribution of the number of appearances are grouped, and business flows generated for respective groups are integrated.Type: ApplicationFiled: November 7, 2016Publication date: May 18, 2017Applicant: HITACHI, LTD.Inventors: Yasunori HASHIMOTO, Ryota MIBE, Hirofumi DANNO, Katsumi KAWAI, Keishi OOSHIMA, Kiyoshi YAMAGUCHI, Makoto KIMURA

Publication number: 20060236241Abstract: The objective of this application is to make it possible to timely acquire the user's evaluation about evaluation-targeted content. A survey window is provided to include a title region, an operation region and a content region. The content region indicates the evaluation-targeted content that the evaluator evaluates. The operation region indicates photographs of agent's faces as help buttons, and feeling input buttons that the evaluator selectively operates according to the emotion experienced when estimating the evaluation-targeted content. The evaluator selectively operates the feeling input buttons when the evaluator experiences an emotion while browsing the evaluation-targeted content to estimate. Thus, the evaluation about the evaluation-targeted content can be more accurately obtained.Type: ApplicationFiled: February 6, 2004Publication date: October 19, 2006Inventors: Etsuko Harada, Takafumi Kawasaki, Hitoshi Yamadera, Yuuki Hara, Ryota Mibe, Nozomi Uchinomiya, Yoshinobu Uchida, Yasuhito Yamaoka, Keiji Minamitani, Katsumi Kawai, Jun Shino, Takahiro Inada, Chiaki Hirai, Kaori Kashimura
