master file includes descriptive data, such as the name and the address, in

Transaction files also serve as audit trails and history for the organization.
There can be many more fields depending on the organization. The account number
is usually the primary key, but name may also be used as a primary key. The

File Merging: File merging
also called file integration) is a fundamental operation that reconciles
multiple changes made to a collection of files. Most often, it is necessary
when a file is modified by two people on two different computers at the same
time, the two files are merged into a single collection of files that contains
both sets of changes.
