Zachman Framework for Enterprise Architecture
In 2003, John Zachman updated his Zachman Framework for Information Systems to classify descriptive representations contributing to an enterprise architecture. This framework is also represented by a matrix.
Each of the six columns contains a basic interrogative and what it represents in a functioning enterprise:
What - Data; |
Who - People; |
How - Function; |
When - Time; |
Where - Network; |
Why - Motivation. |
Each of the five rows represent a perspective:
Planner - Scope (Contextual); |
Builder - Technology Model (Physical); |
Owner - Business Model (Conceptual); |
Sub-Contractor - Detailed Representation |
Designer - System Model (Logical); |
(Out-of-Context). |
The sixth row represents the Functioning Enterprise itself and the actual physical manifestation of the end product. In addition, each of the thirty cells within the matrix has a name.
Zachman Framework for Information Systems Architecture
A two-dimensional framework for classifying design artifacts contributing to an enterprise information systems architecture. A grid model based on 6 basic questions (What, How, Where, Who, When, Why) asked of 6 stakeholder groups (Planner, Owner, Designer, Builder, Subcontractor, System) to give an holistic view of the enterprise. Conceived by John Zachman in the 1980s.
zero-or-one-to-one (0..1:1)
The characteristic of a relationship in which a member of population A may be related to only one member of population B, and a member of population B may not be related to a member of population A. For example, a person (B) and a date of death (A). SEE ALSO cardinality.
zero-or-one-to-one-or-Many (0..1:1..M)
The characteristic of a relationship in which a member of population A may be related to one or more members of population B, and a member of population B may not be related to a member of population A, or may only be related to one member of population A. SEE ALSO cardinality.
zero-or-one-to-zero-or-Many (0..1:0..M)
The characteristic of a relationship in which a member of population A may be related to none, one, or multiple members of population B, and a member of population B may not be related to a member of population A, or may only be related to one member of population A. For example, a person (B) and a doctor (A). A person may not have a doctor, and a doctor may have zero, one or more people as patients. SEE ALSO cardinality.
zero-to-Many (0:M)
SEE zero-or-one-to-one-or-Many; zero-or-one-to-zero-or-Many.
