Abstract: A method for migrating data from a legacy system is provided. The method comprises providing a legacy database having metadata describing one or more legacy data fields in the legacy database and creating a legacy value table in the legacy database that corresponds to a recipient value table in the recipient database. Further, the method comprises updating a translation table in the legacy database that defines one or more recipient data elements in the recipient database based upon the metadata of the legacy database, and translating legacy data elements in the legacy database to correspond to the one or more recipient data elements in the recipient database by utilizing the translation table. Furthermore, the method comprises populating a legacy interface table using the translation table and remotely extracting the data from the legacy interface table to the recipient database.

Abstract: A method for updating data in a database is provided. The method comprises initiating a plurality of tasks adapted to update data in the database, wherein the plurality of tasks run substantially contemporaneously. The method further comprises automating a collection of statistics associated with and subsequent to completing a first batch of the plurality of tasks running to completion, wherein the collection of statistics optimize performance of any remaining batches of the plurality of tasks running to completion. Further, the method comprises automatically submitting a next task of the plurality of tasks when a task of the plurality of tasks has been processed, until each of the plurality of tasks has been processed for updating the data in the database. Additionally, the method comprises generating a log file summarizing an outcome for each of the tasks subsequent to completion of all tasks of the plurality of tasks.

Abstract: A method of compensating for carrier frequency and phase errors of a received multi-carrier modulated signal. The received multi-carrier signal including modulated carriers for transmitting known data and unmodulated carriers for error correction, comprising, time domain down converting the received multi-carrier signal to base-band to provide a down-converted signal, the down-converted signal including a plurality of modulated carriers for transmitting known data and unmodulated carriers for error correction. Sampling an unmodulated carrier of the down-converted signal to provide received data samples. Providing a reference signal derived from the unmodulated carrier of the down-converted signal. And, estimating phase errors from a phase difference between the ummodulated carrier and the reference signal derived from the unmodulated carrier of the down-converted signal to provide a plurality of received sample phase error estimates for each modulated carrier.
