Backup - Incremental

An incremental backup stores only the data that has changed since the previous full or incremental backup.

Backup - Typical

A non-incremental backup without journal archiving. Most of the time when a typical backup is running, all queries and updates proceed as usual. MarkLogic copies stand data from the source directory to the backup target directory, file by file.

Backup with Journal Archiving

The backup/restore operations with journal archiving enabled provide a point-in-time recovery option that enables you to restore database changes to a specific point in time between full backups with the input of a wall clock time.

backward-chaining inference

Semantics. Backward chaining inference is inference done at query time; each query looks at the ontology and expands the query appropriately. Backward chaining inference is more resource intensive at query time, but less costly during ingestion and indexing. See also forward-chaining inference and inference.

bastion host

Cloud. A bastion host is a server that provides access to a private network from an external network.

bearer token

Security. An encoded token that can be used for a specific purpose by any party.

bitemporal

MarkLogic. Bitemporal documents are associated with both a valid time and a system time. Data in a bitemporal format provides the user with a complete history (audit trail) of data in the database. For more information, see Understanding Temporal Documents in Understand Bi-Temporal Concepts. See also non-temporal.

blank node

Semantics. (also known as a bnode or anonymous resource) A subject or object in an RDF graph that has no Internationalized Resource Identifier (IRI) or resource identifier. Typically used to group together other values for a triple. A blank node is represented by a prefixed name with an underscore prefix (_:mytriple). See bnode.

BLOB (Binary Large Object)

Database. Binary data stored as a single entity. Typically BLOBs are images, audio, or other multimedia objects.

BN (Backus Normal Form or Backus–Naur Form)

General. A notation technique for context-free grammars, often used to describe the syntax of languages used in computing.

bnode

Semantics. A node in an RDF graph representing a resource for which an Internationalized Resource Identifier (IRI) or literal is not provided. This term can be used interchangeably with blank node .

Bootstrap Host

MarkLogic. A MarkLogic Server host machine used by a foreign cluster to initiate communication with the local cluster.

built-in

MarkLogic. A built-in function (or main module) is one that can be called without using import module in XQuery or JavaScript. MarkLogic built-ins are accessed through XQuery or JavaScript. See module.
