Manufacture Columns

A column is the joining together of an Table and a Data Element. The Table provides the overall policy-context within the scope of the Schema for the Columns which, in turn, acts as a data-based property descriptor for the Table.

There are four classes of data-based properties, that is, Columns, that can be assigned to Tables. The classes are:

  • Uniqueness -- the value of one or more data-based properties that when used as a selector retrieves one and only one instance.
  • Audit -- the data-based properties that enable knowing the metadata surrounding the Who, What, When, Where, Why, and How of a created or updated instance.
  • Relationship -- the data-based property that is subsequently employed in a different Table to enable a value-based relationship between the "parent" Table and the "child" Table.
  • Content -- the data-based properties that inform the policy-based content that is to be represented by an instance.

For the Implemented Data Model, the Column required classes are Uniqueness, Audit, Relationship and Content.

The process to manufacturing Columns includes:

  • Start the Implemented Database Model Metabase System Module
  • Select the DBMS
  • Enter User Name and Password
  • Select the Menu Item, Columns
  • If the task is to create one Columns across many Tables, select the subordinate menu item, Create One Column Many Tables
    • Select a Business Domain
    • Tag one Data Element
    • Select the first Tale
    • Select and tag one or more Tables within that Schema
    • Press the Build button
  • If the task is to create many Columns within one Table, select the subordinate menu item, Create Many Columns One Table
    • Select a Schema
    • Tag one Table
    • Select an appropriate Business Domain
