# 文書変更(Document Change) 
>• Improved the clean up and the version handling during update
• Removed local handling of minimumSustainedSize
• Removed constraints regarding storage sync
• Formal description of dependencies to other Functional Clusters
# 用語(terms)

|Term| Description|
|:--|:--|
|FS| File Storage|
|KVS| Key-Value Storage
|Adaptive Application| Refers to the Adaptive Application defined in [1].
|Adaptive Platform| Refers to the AUTOSAR Adaptive Platform defined in [1].
|Adaptive Platform Foundation| Refers to the Adaptive Platform Foundation defined in [1].
|Element| Refers to either a key-value pair of a Key-Value Storage or a file of a File Storage. Used in the specification where something applies to all kinds of storage elements.
|Execution Manifest| Refers to the Execution Manifest defined in [1].
|File| A binary or text file to be stored in a File Storage.
|File Name| The file name uniquely identifies a file within a File Storage.
|File Storage| A set of files that are stored persistently.
|Functional Cluster| Refers to the Functional Cluster defined in [1].
|Integrity| Persistency distinguishes data integrity, which is ensured by the configured redundancy, from structural integrity, i.e. the readability of the structure of a Key-Value Storage or File Storage.
|Key| The key uniquely identifies a key-value pair within a Key- -Value Storage.
|Key-Value Pair| A key with an associated value, to be stored in a Key-Value Storage together with the type of the value.
|Key-Value Storage| A set of key-value pairs that are stored persistently.
|Persistency| The functional cluster described in this document, which handles persistent data of AUTOSAR Adaptive Applications and other functional clusters in File Storages and Key-Value Storages.
|Persistent Data| Data that is stored in the persistent memory that can be accessed by one Process. Persistency supports different mechanisms to access data in persistent memory. Concurrent access to the data by several Processes is not supported as the data is owned exclusively by one Process.
|Redundancy| Redundancy is used by Persistency to ensure the integrity of stored data. It can be configured to use replication of stored data, CRCs, or Hashes. Typically, only replication will allow to repair corrupted data.
|Service Interface| Refers to the Service Interface defined in [1].
|Software Package| Refers to the Software Package defined in [1].
|Storage| Refers to either a Key-Value Storage or a File Storage. Used in the specification where something applies to all kinds of storages.
|Value| A value of a key-value pair stored in a Key-Value Storage.|
