Share Data

urn:js:virtue:aspire:principle:4.1

TL;DR

Data from the various source systems must be conformed and consolidated (where appropriate) into integrated views which will be shared with all authorised users.

Rational

Data from the various source systems must be conformed and consolidated (where appropriate) into integrated views which will be shared with all authorised users.

Note: When applying this principle due consideration must be given to the legal and regulatory as well as the supplier constraints (see Section 4.3.4).

The key drivers for sharing data from a centralised data store are:

• Single version of the truth – Data from the numerous operational systems (as well as external sources) will be integrated to provide a “single version of the truth” and then made available to the users.
• Eliminate data inconsistencies – Having separate repositories will inherently result in data inconsistencies between them. Having a centralised data store will eliminate such inconsistencies.
• Reduce maintenance costs – Having a centralised data store is less costly to maintain than having separate repositories of duplicated data for the various groups of users as changes are only implemented in one place.

Implications

The potential implications for sharing data from a centralised data store across disparate groups of users are:

• Collaborative approach –The various user groups need to adopt a collaborative approach towards the maintenance and access of the data.
• Enterprise Data Model – Sharing metadata and conforming to an enterprise data model will go a long way towards ensuring the efficacy of the common shared environment.
• Data security – Giving users access to a common shared environment places a greater emphasis on managing data security more rigorously.
