ACID ([Atomicity](#atomicity), [Consistency](#consistency), [Isolation](#isolation), [Durability](#durability)) are properties of database transactions that are generally considered desirable for many applications.

Subdocuments can be deleted using the `delete_document` keyword, but it's important to also delete the triple that links the subdocument from the parent document. Here we resolve the parent document in the variable `v:parentdoc`.
Let's combine creating and deleting a document into a single query to update the subdocument.

Subdocuments can't be updated in place using the `update_document` keyword which exists only for top level documents. You can update a subdocument by deleting the old subdocument and creating a new one with the updated content, including the `@linked-by` property, and updating the triple that links the subdocument.

This in place operation is only possible using random keyed identifiers on the subdocument. The alternative is to update the top level document.
The parent document is resolved for the specific predicate, the old document gets deleted and a new document is created, linked to the parent document and the triple that links from the parent document is updated.

The old and new subdocuments are provided in the returned bindings via the selections of variables to return.

TerminusDB exposes a _filter_ object, which can be used to select specific documents. See here for basic [Filtering](/docs/filter-with-graphql/)
This example shows how `<FrameViewier/>` appears for a document `ArrayExamplePerson` with array fields in Create/ Edit or View mode. If a field is described as array it means the field can have more than one value to it in an ordered fashion. The field can also be considered as an optional field meaning it can be empty or filled.
