complex data type

Any data that does not fall into the traditional field structure (alpha, numeric, dates) of a relational DBMS. Examples of complex data types are bills of materials, word processing documents, maps, time-series, images and video. In a relational DBMS, complex data types are stored in a LOB, but either the client application or some middleware is required to process the data. In an object DBMS or an object-relational DBMS, complex data types are stored as objects that are integrated into and activated by the DBMS.

What should exist is a "range" or perhaps an "interval" complex data type that consists of a start and a stop date, yet could still be considered a single attribute and could be "matched" directly against an external date to respond positively/negatively saying this "interval" was/wasn't active at that point-in-time Maybe "data type" is an imprecise term, maybe "domain" would be more appropriate, but the terms both have spilled across each other.
