Idinterval

Idinterval is not a widely defined term in standard mathematical or computer science literature. The form idinterval combines the words “id” (often short for identity or identifier) and “interval,” and its meaning is highly context dependent. In practice, the phrase may be encountered in different domains to refer to different concepts.

In computing and data management, an id interval often denotes a contiguous block of identifiers assigned to objects or records. For example, a database or service might designate the range of IDs from 1000 to 1999 as an id interval. Such intervals facilitate efficient indexing, range queries, partitioning, and validation of identifiers within a system.

In mathematical or formal contexts, some writers may use “id interval” informally to describe a subinterval on which a function acts as the identity, or where the identity map is considered as a fixed-point map. This usage is not standard and should be clarified by the author, as it can be ambiguous.

Other uses may simply refer to any interval one uses to identify a range of items or IDs, again defined entirely by the surrounding context. Because there is no universal definition, readers should consult the specific source or field where the term appears to determine the intended meaning.
