Describing access paths for database files

An access path describes how records in a database file are retrieved. You can define the access path for a database file in various ways.

Records in a physical or logical file can be retrieved through an arrival sequence access path or a keyed sequence access path. For logical files, you can also select and omit records based on one or more field values in each record. A key field is a field that is used to arrange the records of a particular type within a file member.
