Quick Reference for Basic SBVR Terminology (5)
| The Semantics of Business Vocabulary andBusiness Rules (SBVR) uses thefollowing designations, with informal meanings as indicated. Terms new this article are in blue. |
- notation
- a language used to represent semantics or, more precisely, abstract syntax
[Notations can be verbal, graphical, or any combination thereof. Other words for 'notation' are 'grammar', 'syntax', and 'concrete surface syntax'. Notation is nonnormative in the SBVR standard, although three notations are discussed in informative annexes of the standard.]
- SBVR Structured English
- the particular way of using English that maps mechanically to SBVR concepts, as described in Annex A of the SBVR specification
[SBVR Structured English is not meant to offer all of the variety of common English, but rather, it uses a small number of English structures and common words to provide a simple and straightforward mapping.]
- RuleSpeak®
- the business rule notation developed by Business Rule Solutions, LLC (BRS)
[RuleSpeak has been used with business people in actual practice in large-scale projects since the second half of the 1990s.]
- prefixed rule keyword style
- a style of rule statement that prefixes the statement with a keyword that conveys the rule's modality
- embedded rule keyword style
- a style of rule statement that uses modality-conveying keywords embedded in the statement (usually in front of the verb)
- modality
- a way (or mode) of considering some proposition; a classification (category) of propositions with respect to characteristics as being necessarily true, possibly true, obligatory, permissible, etc.
[In SBVR, the two main modalities are: alethic modality — the modality of necessity (also including possibility, etc.) and deontic modality — the modality of obligation (also including permission, etc.). Alethic modality aligns with SBVR definitional (or 'structural') rule; deontic modality aligns with SBVR behavioral (or 'operative') business rule.]
- alethic modality
- a way (or mode) in which a given proposition might be true or false: necessity, possibility, and impossibility
In contrast to deontic modal logic, alethic modal logic deals with people's estimate(s) of the possible truth of some proposition.
[Note: 'contingency' — one of the historical modes — is not considered business-relevant and thus ignored by SBVR.]
- deontic modality
- a way (or mode) in which one might think of the social desirability of a certain other person(s)'s making true some proposition, that is, the social desirability that the act(s) be performed, by a certain other person(s), that would make the proposition true; viz., permission, obligation, and their respective negations: nonpermission (forbidden/prohibition) and non-obligation
In contrast to alethic modal logic, deontic modal logic deals with people's estimate(s) of the social desirability of some particular party's making some proposition true.
- modal operation
- a logic operation used in the formulation of business rules, having a representation in business rule statements by a specified key word or phrase, or by a special symbol that means the operation
[E.g., the meaning represented by the modal operators: 'it is necessary', 'must', ▢ )
- EU-Rent
- the (fictitious) car rental company
[This popular case study was contributed to the SBVR effort by Model Systems and appears in detail as Annex G of the SBVR document.]
- behavioral business rule (or operative business rule)
- a business rule that obligates a given state of affairs
(informally) a business rule that is intended to shape the behavior of people — even when that behavior is automated; a prescribed guide for conduct or action [MWCD 'rule']
- behavioral business rule statement
- a rule statement that expresses a behavioral business rule
- body of shared meanings
- a set of concepts and elements of guidance for which there is a shared understanding in a given semantic community
- business policy
- an element of guidance that is not directly enforceable, whose purpose is to guide an enterprise
Compared to a business rule, a business policy is not directly enforceable and tends to be less structured, less discrete (not atomic), and less carefully expressed in terms of a standard vocabulary.
- business rule
- a rule that is practicable and that is under business jurisdiction
- Business Rules 'Mantra'
- an approximation that provides a simplified explanation of the business rules approach for business people and others new to approach
(simple form) "Rules are based on facts, and facts are based on terms."
(more precise form) "Rules build on facts, and facts build on concepts as expressed by terms. Terms express business concepts; facts make assertions about these concepts; rules constrain and support these facts."
- Business Rules Team (BRT)
- the multi-national consortium, formed expressly to respond to the OMG's "Business Semantics of Business Rules" RFP
After the BRT's RFP submission was selected, BRT members, along with other individuals, then worked as the SBVR Finalization Task Force, the group that brought SBVR 1.0 to completion in December 2007.
- business vocabulary
- a vocabulary (structured set of terms and other symbols together with their meanings and relationships among them) that is under business jurisdiction
- business vocabulary+rules
- a business vocabulary plus a set of business rules specified in terms of that business vocabulary
- community
- a group of people having a particular unifying characteristic in common
- concept
- a unit of knowledge created by a unique combination of characteristics
- concept model
- a set of concepts within a body of shared meanings, structured according to the relations among them
- definitional business rule (or structural business rule)
- a definitional rule that is a business rule
- definitional rule (or structural rule)
- a rule that necessitates a given state of affairs
(informally, a rule that is intended as a definitional criterion)
- definitional rule statement
- a rule statement that expresses a definitional rule
- designation
- a representation of a concept by a sign which denotes it
- element of guidance
- a means that guides, defines, or constrains some aspect of an enterprise
- enforcement level
- a position in a graded or ordered scale of values that specifies the severity of action imposed in order to put or keep a behavioral business rule in force
- expression
- something that expresses or communicates, but [is] independent of its interpretation
- extension
- the totality of objects [every thing] to which a concept corresponds
- impossibility statement
- a definitional rule statement that is worded as the state of affairs being impossible or beingnever the case
- ISO terminology standards
- • ISO 1087-1 (2000) "Terminology work — Vocabulary — Theory and application"
• ISO 704 (2000) "Terminology work — Principles and methods"
• ISO 860 (1996) "Terminology work — Harmonization of concepts and terms"
- logical formulation
- a semantic formulation that formulates a proposition
(informally) the SBVR conceptualization of formal logic
- meaning
- what is meant by a word, sign, statement, or description; what someone intends to express or what someone understands
(informally, how we think about things)
- necessity statement
- a definitional rule statement that is worded as the state of affairs being necessary or being always the case
- Object Management Group (OMG)
- an international, open membership, not-for-profit computer industry consortium whose members develop enterprise integration standards for a wide range of technologies
Numerous standards organizations and other consortia maintain liaison relationships with the OMG.
- obligation statement
- a behavioral business rule statement that is worded as the state of affairs being obligated
- prohibition statement
- a behavioral business rule statement that is worded as the state of affairs being prohibited
- representation

- a behavioral business rule statement that is worded as the state of affairs being permitted only if a given condition is met
- restricted possibility statement
- a definitional rule statement that is is worded as the state of affairs being possible only if agiven condition is met or being possibly the case only if a given condition is met
- rule
- a proposition that is a claim of obligation or of necessity
The two fundamental categories of 'rule' are:
• behavioral rule (obligations), also known as 'operative rule'
• definitional rule (necessities), also known as 'structural rule'
- rule statement
- a guidance statement that expresses a behavioral business rule or a definitional rule
