Systems and methods for collecting, correlating, and storing telecom data as call detail records (CDRs) are described. A computer system collects real-time call data from a plurality of sources and stores the data in different memory locations. A real-time buffer is used to correlate the data into a CDR. A separate process collects reference data from one or more third-party sources to supplement each CDR and stores this data in different memory locations. A reference data buffer is then used to correlate the reference data into existing CDRs. A data manager layer then inserts each enhanced CDR into a plurality of distributed database systems. CDRs may be separated among multiple database systems, may be inserted into more than one database depending on application use, and may be partitioned to optimize access and retrieval.
