<p>Provided is a data retrieval system wherein a user can perform an arbitrary search which meets his/her purpose, using various data collected in an industrial plant, and the retrieval result can be displayed in a desired display format with respect to each product. In the data retrieval system, a data collection device (3) collects product data with respect to each product produced in a rolling line of an industrial plant, and the product data is accumulated in a data accumulation device (4). The data collection device (3) also collects control data continuously generated in the industrial plant, and accumulates the data in the data accumulation device (4). A data retrieval device (6) performs a search using both the product data and the control data accumulated in the data accumulation device (4), on the basis retrieval conditions and an output method designated by the user, with reference to rolling area definition information in a storage device, and outputs the retrieval result for each product.</p> |
