Abstract:
1. A computer-implemented method for modifying database construction information for a database system having a plurality of databases and meta information including database metadata relating to schema definition of the database, wherein the database construction is modified by changing the schema definition, comprising the steps of: providing job metadata including item mapping for defining correspondence relation between databases and jobs for defining data transformation between databases in said meta information; holding modification pattern information comprising a plurality of modification patterns wherein a modification to a system is designated by a variable and said modification pattern information further comprising management information for identifying a location to be influenced by said variable; prompting a user to select a variable to designate relevant modification from a plurality of modification patterns; detecting modification influence ranges of said schema definition and said data transformation between the databases on the basis of said meta information in accordance with the selected variable, and performing modification range detecting operation to output the influence range of said meta information as influence range information; and executing system construction information modifying operation to generate system construction information for setting and execution of a middleware by modifying the schema definition held in said meta information, the data transformation and at-runtime reference information.
