Enterprise resource planning
Data migration is the process of moving, copying, and restructuring data from an existing system to the ERP system. Migration is critical to implementation success and requires significant planning. Unfortunately, since migration is one of the final activities before the production phase, it often receives insufficient attention. The following steps can structure migration planning:Often, data migration is incomplete because some of the data in the existing system is either incompatible or not needed in the new system. As such, the existing system may need to be kept as an archived database to refer back to once the new ERP system is in place.
High frequency data
"Data Management" refers to the process of selecting a specific time-series of interest within a set of ultra-high frequency data to be pulled and organized for the purpose of an analysis. Various transactions may be reported at the same time and at different price levels, and econometric models generally require one observation at each time stamp, necessitating some form of data aggregation for proper analysis. Data management efforts can be effective to remedy ultra-high frequency data characteristics including irregular spacing, bid-ask bounce, and market opening and closing.
