A practical structure for a very large time sequential data base

ABSTRACT

This paper discusses the practical aspects of incorporating an indexed sequential file structure into a large time sequential data base, which includes the sequence of intervals between heartbeats measured from the electrocardiogram (ECG). First, the paper describes the time sequential data base. Secondly, the paper presents uses made of the time sequential file. Finally, the paper describes the indexed sequential data structure developed to support this application.
