One advantage of using a data repository instead of the original database in the host application or
device is that longitudinal studies are possible because all data in the host application are mirrored
and stored in the repository. For example, because of storage limitations, or because the local
database is always in use, it may be virtually impossible for a researcher to compare data from
multiple runs of a sequencing machine. Another advantage of using a data repository instead of the
original database is that it offloads the query functions that are available through native applications
to the database management system that enables efficient control and management of the data
repository.
Next up the hierarchy of complexity and capability is the data mart, a searchable database system,
