Amazon developed several purpose-built persistence solutions, including its own key-value store and single table store.
Resolved true The record shows it happened or was so.
Factual: Statements about the present or the past, checked against the record: did they hold up?
The second judge would not resolve this claim; the verdict shown is the first judge's.
The evidence is the person's or their organisation's own records.
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
Judge as of 2011. True: Amazon technical publications or official descriptions show that Amazon had developed several purpose-built persistence or storage systems by 2011, including its own key-value store (for example Dynamo) and a single-table store (for example SimpleDB or a similar service). Mostly true: it had developed several such systems, but one of the two named types is described a little inaccurately. Mixed: only one of the two named systems existed. Mostly false: Amazon used such stores but did not develop them itself, or only one system existed and is overstated as 'several'. False: Amazon had developed no such systems.

“To meet the reliability and scaling needs, Amazon has developed a number of storage technologies, of which the Amazon Simple Storage Service (also available outside of Amazon and known as Amazon S3), is probably the best known.”

E3 [PDF] Dynamo: Amazon's Highly Available Key-value Store Giuseppe DeCandia, Deniz Hastorun, Madan Jampani, et al. (Amazon.com authors), hosted on allthingsdistributed.com Own record
“This paper presents the design and implementation of Dynamo, a highly available key-value storage system that some of Amazon’s core services use to provide an “always-on” experience.”
Reasoning
The Dynamo paper by Amazon.com authors presents Dynamo as Amazon's own key-value storage system, used by some of its core services (E4). The same paper says Amazon had developed a number of storage technologies, including S3 (E3). The 2010 shareholder letter names SimpleDB, the example of a single-table store given in the criteria, among services built on Amazon's own technologies (E2). Together these Amazon technical and official records support the claim, but none of the sources is independent, and the evidence does not describe SimpleDB's design.
