The Data Layer

This layer provides data-specific software clustered in ‘Data Access’ and ‘Data Storage’ elements. The distinction between these two clusters is based around the separation of responsibilities and of functionality (i.e. access is provided, but only for the storage of Master data). The notice of different data types for storage is essential on enterprise level. Different data types may also need different technology for data access.

The basis of all, your data

Introduction

We are thriving on data. We come from a time where data only belonged to one application, but now data-combinations of any sort within and outside the enterprise are possible. Without data and accompanying good data management enterprises would be lost. The data layer has been separated in the CORA model because of its importance for the enterprise. The data layer within the CORA model contains two main clusters, Data Access and Data storage. The distinction between these two clusters is based around the separation of responsibilities and of functionality.
