files also serve as audit trails and history for the organization. The
following are the kinds of fields that make up a typical transaction record in
an information system. There can be many more fields depending on the
organization. The “key” fields are the ones that are generally

File Merging: File merging
which is sometimes referred to as file integration is a type of file processing
operation that is used to cater for changes that may occur when a files
