Unstructured Data, Non-modifiable
Data is stored as discrete files with no specific organization or relationships between the files. Non-modifiable data is generally images, video stream files, music stream files, etc. They are written and stored but not modified or edited after writing. Often the data is storage and managed by an application. Non-modifiable unstructured data can also include data types that would normally be modifiable but are being kept for data retention purposes so modification is prohibited by policy.
