  • Patent number: 11138173
    Abstract: 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.

  • Patent number: 10489428
    Abstract: The present invention has an object to analyze, regarding an existing system without a source code, the relationship between input items and internal system processing with respect to output items and present the analysis results to a user. An existing system processing specification extractor is an apparatus for making an existing system operate and analogizing input items of the existing system and internal system processing patterns without performing analysis of implementation and includes: an output data change information acquisition unit that classifies changes of output data associated with input to the existing system on the basis of types of changes of each output element; and an internal system processing specifying unit that combines the classifications obtained by making different input to the existing system and specifies a type of processing based on a usage pattern of an input item value.

  • Publication number: 20170140309
    Abstract: 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.

  • Patent number: 9178189
    Abstract: Disclosed is a sheet-type secondary battery having: a laminated sheath (2) including an inner layer (2a) made of a thermoplastic resin and a metal layer (2b); and electrode terminals (3), each of which is connected electrically to an internal electrode pair (1) and passes through a heat seal portion (20) of the laminated sheath (2) in a hermetic manner so as to be led out externally. The sheath (2) and electrode terminal (3) are bonded with a bonding resin (5) at portion (20) in which terminal (3) is interposed. The inner layer (2a) of the sheath (2) opposed to the terminal (3) has an excess resin receiving portion (20a) formed thereon for receiving an excess resin in a heat sealing process. The portion (20a) is not formed in a heat seal portion (20P) at which the inner layers (2a) of the laminated sheaths (2) are bonded.

  • Publication number: 20060236241
    Abstract: 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.
