Research On The Construction Of Network Knowledge Base Of Ferrous Materials

The standard of ferrous materials is an important technical system to regulate the development of economy and society. It’s played an important role in ensuring product quality, promoting the circulation of goods and so on. The producer uses the ferrous material standard in the production. The output conforms to the standard. However, the current manufacturers using the ferrous materials standard may select standard through the print editions of handbook. When using the print editions of handbook to select standard, it highlights the inefficiencies and data expiration and other issues. With the development of computer technology, the paper books are no longer the only carrier of data. Data information can be used as a carrier of the computer. The networked material knowledge base can be more convenient to share and update data in a timely manner.The material knowledge base is constructed through system development and standard data input. The main research contents of this paper as follows:(1) According to the classification of categories, the each category of black metal materials standards is found. The classification results of ferrous materials is determined. The current standard is downloaded through the network. It takes a lot of time to export as the text file from data of standards files.(2) The analysis and design of knowledge base system. Be analyzed from the functional requirements, the network needs, the demands of data. It describes the differences between browser/server mode and client/server model. Finally, the structure and function of the system are designed.(3) The analysis and selection of database. Finally, the MySQL database is selected, the Tomcat server is selected, it describes the operation of the database language SQL.(4) The knowledge base has been designed through conceptual design, logical design, physical design. The properties of standard of ferrous materials are designed and the user attributes are designed. Then the field tables of MySQL are designed. Finally, data were entered into a database table.(5) Building the page and the function of the knowledge base system. Including the login page, the knowledge base system home page and the function of adding, the function of revision and the function of deletion. It also describes the rights of the users. Through the javaBean technology, the database access and operation is convenient.
