Data Models Across the End-State Architecture

Abstract

One of the essences of data architecture is an overall blueprint of the architecture. The composite architecture combining all data is shown to contain different layers of data. There are interactive data, archival data, integrated data, and other forms of data. The composite data architecture recognizes the life cycle of data within the corporation. Another view of architecture is that of how corporate data interface with big data.

Keywords

Architectural blueprint; The composite architecture; The lifecycle of data; Big data; Textual disambiguation; Repetitive data; Nonrepetitive data

There are different kinds of data models that are found throughout the end-state architecture. ...
