AUTOMATIC METHOD FOR GENERATING ESS NMS DATABASE LOADER WHICH STORES DATA OUTPUT FROM TELEPHONE EXCHANGE INTO DATABASE

摘要

PURPOSE: A method for automatically generating exchanger operation and management database loader is provided to reduce human power and time by automatically developing a database loader. CONSTITUTION: Data for operating and managing an exchanger is received(21). A lexical rule to the data is automatically generated and stored in a file(22). A token generator is generated by compiling the corrected source code by using lex(23). A token and parser.y are generated by supplementing parser.y by inserting action code extracting symbol value of an item(24). Parser.1 of a syntax analyzer is generated by using the inserted lexical rule and symbol value extracting code by token list(25). A database loader is generated by compiling the generated syntax analysis rule and parser.1 and linking DB input routine(26).
