The following statement, already requesting cite is probably outdated, but regardless may not contribute to the overall value of this article:

"An alternative approach is point-to-point data updates, but these become exponentially more expensive to maintain as the number of systems increases, and this approach is increasingly out of favour as an IT architecture."

With the advent of Semantic Web Technology and it's general adoption as an emerging trend, it is actually probably not true. Regardless, I recommend the deletion of this line as it is both un-cited and expresses opinion - without adding significant value to an otherwise fine article.

The first reference, "IBM Smarter Planet - Operational risk management for financial services" is a broken link (http://www.ibm.com/smarterplanet/za/en/banking_technology/nextsteps/solution/Z017038Z16405R75.html). Does someone know what article was referenced and how to find it? — Preceding unsigned comment added by Twelve12pm (talk • contribs) 21:42, 4 October 2017 (UTC)[reply]

This part of the article, and the associated reference, appears to have been inserted as an ad/promoting commercial content:

Data Access and Field Productivity Adoption of a single source of truth execution model is on the rise in the energy sector, where the technological advancements brought about by Industry 4.0 have enabled operators to improve field productivity. With an accessible SSOT for an industrial asset, owners are able to maximize worker efficiency by providing wireless mobility that enables on-demand access to verifiable field data, engineering drawings and inventory and communications with centralized operations experts.[5]
