Abstract: A system and method for storing and retrieving performance and topology information of a telecommunications network. A network performance data parser receives network performance data messages in real time, parses the messages according to parsing rules, reformats the messages according to the parsing rules, and writes out the reformatted messages to a performance data file. A network performance data loader retrieves the reformatted messages from the performance data file and loads them into an open database management system. A topology data loader retrieves weekly network topology data from a topology data file and loads it into the open database management system. A SONET data loader retrieves daily network SONET data from a SONET data file and loads it into the open database management system. The open database is easily accessible via any SQL interface.
