The present invention discusses a computerized method for managing a communication network through processing data used in a Capacity Management System (CMS) associated with the communication network. A configurable grammar, such as an XML grammar with regular expressions, is used to implement various aspects of network management. Data management includes pre-processing data (transferring data, decompressing data, parsing data), loading data into a relational database, and data analysis. Results of data analysis can be used to determine a network condition, and thereby to enable network management.
