The Wolfram Language provides streamlined mechanisms for persistent storage between sessions, both locally and in the cloud.

Local Storage »

LocalObject — a handle to a persistent expression or other content stored locally

LocalSymbol — a symbol whose value is persistently stored locally

LocalCache — cache cloud objects and URLs in local objects

Cloud Storage »

CloudObject — a handle to an expression or other content stored in the cloud

CloudExpression — a handle to an expression whose parts can be manipulated directly

CloudSymbol — a symbol whose value is stored in the cloud

Basic Operations for Local & Cloud Storage

Put  ▪  Save  ▪  Get  ▪  Export  ▪  Import

CloudDeploy — deploy active content in the cloud

CreateCloudExpression  ▪  CreateDatabin

DeleteObject — delete a cloud object, local object, etc.

CopyFile — copy between cloud objects, local objects, etc.

Utilities

CreateUUID — create a universal unique identifier

URLShorten — create a shortened version of a URL

Structured Persistent Storage

ResourceObject — a structured resource to be deployed or published in the cloud

Databin — storage for incrementally added data in Wolfram Data Drop

Blockchain Storage »

BlockchainData — data on public and private blockchains

BlockchainPut  ▪  BlockchainGet

System Credential Storage

SystemCredential — store passwords in your operating system's secure credential store

$SystemCredentialStore — the currently active credential store

SystemCredentialData  ▪  SystemCredentialKeys  ▪  SystemCredentialKey

$DefaultSystemCredentialStore  ▪  SystemCredentialStoreObject

General Persistent Objects »

PersistentSymbol — settable persistent value for session, user, installation, etc.

PersistentObject  ▪  PersistenceLocation

Initialization »

InitializationValue — settable initialization value for session, user, installation, etc.

$Initialization  ▪  $PreInitialization  ▪  InitializationObjects

User Interface Preferences

$FrontEnd — symbolic representation for the Wolfram System front end

SetOptions — programmatically set persistent preferences
