Definition: Immutable Database Manager ABB is a Technology Service that enables the procedure to manage data that cannot be (or shouldn't be) deleted or modified. Source: ODBMS Source reference: https://www.odbms.org/2015/10/the-rise-of-immutable-data-stores/ Example: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): immubd is a database written in Go, but unlike other databases, it is immutable: history is preserved and can't be changed without clients noticing. immudb can be used both as a key-value store, or as a relational database (SQL). immudb can be run as full database server with replicas or easily embedded as a lightweight database into application. https://docs.immudb.io/master/ eira:iopDimension: Structural IoP LOST view: TVI-Trust Infrastructure Enablers [Motivation] eira:iopSaliency: Immutable Database Manager ABB is salient for technical interoperability because it establishes the mechanism to store information and also, manages that the stored information is cannot be deleted or modified.
