Techopedia Explains Information Management System (IMS)
Unlike DB2 (IBM’s relational database software), an IMS database uses segments, or data blocks, as building blocks of the hierarchical model. Within each segment are multiple data pieces, which are known as fields. At the top of the hierarchy, the segment is known as the root segment. Segments of a specific segment are known as child segments. The child segment order represents the order in which each entry is entered in a database.
