Zachmanフレームワーク
The framework comes with a set of rules:
Rule 1 The columns have no order : The columns are interchangeable but cannot be reduced or created
Rule 2 Each column has a simple generic model : Every column can have its own meta-model
Rule 3 The basic model of each column must be unique : The basic model of each column, the relationship objects and the structure of it is unique. Each relationship object is interdependent but the representation objective is unique.
Rule 4 Each row describes a distinct, unique perspective : Each row describes the view of a particular business group and is unique to it.
Eventually the cells with the detailed representation give Rules detail for (Why); Process detail for (How); Data detail for (What); Role detail for (Who); Location detail for (Where); and Event detail for (When).
There is a sixth row in the current Zachman framework, but it is not used for enterprise architecture — while the enterprise is described by rows one to six, enterprise architecture uses only rows one to five, thus only five rows are shown here.
Since the product development (i.e., architectural artifact) in each cell or the problem solution embodied by the cell is the answer to a question from a perspective, typically, the models or descriptions are higher-level depictions or the surface answers of the cell.
