Get started with Ditto's Edge Sync Platform, a mobile database with built-in edge device connectivity and resiliency

Quickstart

Ditto is the only mobile database with built-in edge device connectivity and resiliency, enabling apps to synchronize without relying on a central server or constant cloud connectivity. Through the use of CRDTs and P2P mesh replication, Ditto allows you to build collaborative, resilient applications where data is always available and up-to-date for every user. This allows you to keep mission-critical systems online when it matters most.

What is Ditto?

Ditto stores data records as documents (specifically JSON-like documents) which are gathered together in collections. An application stores one or more collections of documents.

Apps and Collections

Ditto stores data records as JSON-like documents. Internally these documents are CRDTs, which are a binary representation of JSON documents designed for automatic conflict resolution.

Document Model

Learn how to access data in Ditto, including creating, reading, updating, and removing data.

Accessing Data

Ditto automatically synchronizes data between devices in your mesh. Devices are able to express which data they would like to synchronize using subscription queries.

Syncing Data

Ditto provides a flexible identity system to control which devices can participate in data synchronization, who they identify as (authentication), and what they can do (authorization). 
Ditto provides 3 authentication mechanisms: Online Playground, Online with Authentication, and Offline Shared Key.

Authentication and Authorization

The _mesh_ is an underlay for data sync within Ditto, operating independently of your queries and sync subscriptions. Data updates propagate through the mesh automatically to devices with matching subscriptions.

Ditto Query Language (DQL) is a powerful, flexible query language designed specifically for use with the Ditto platform. It allows you to perform complex data operations with ease, enabling real-time synchronization and efficient data management.

Overview

Ditto Query Language Overview

The `SELECT` operation, once executed, retrieves documents from a collection and uses clauses like `WHERE` to specify conditions for filtering the documents to return.

SELECT

INSERT

The `UPDATE` operation modifies the content of existing documents in a collection.

UPDATE

DQL language syntax for deleting documents

DELETE

DQL language syntax for evicting documents locally

EVICT

Ditto Query Language (DQL) offers a set of *data types* designed to accommodate any edge sync scenario.

Types and Definitions

IDs, Paths, Strings, and Keywords

Operators perform a specific operation on the input values or expressions.

Operator expressions

In a typical single-server setup, timestamps remain consistent; however, in a Ditto mesh where there are multiple Small Peer devices distributed across the network, each device may operate on its own time. This can lead to discrepancies where a document's timestamp may seem ahead or documents created simultaneously have different timestamps.

Timestamps

This document outlines functionality in the DQL language that is in active development. This is not an exhaustive list of the features and functionality the Ditto team is tracking concerning DQL and aims to address larger functionality gaps.

DQL Roadmap

In a distributed environment, data structures, schemas, and documents organically undergo changes over time, which can lead to data inconsistencies.

Schema Versioning

When managing complex data structures, choosing the right pattern can significantly impact the efficiency and effectiveness of your app.

Data Modeling Tips

Available in v4.11 and later, strict mode helps Ditto enforce structure and type safety in your collections.

Strict Mode

This article provides a high-level overview of the `ALTER SYSTEM` Ditto Query Language (DQL) statement, as well as instructions on how to use it, once offered, to set, reset, and query peer-to-peer system settings.

Ditto Cloud refers to the trusted cloud deployment of Ditto Server and the associated services that facilitate advanced platform capabilities.

Cloud Platform Overview

browser

A Ditto account provides seamless access to manage your Ditto tenants and utilize Ditto’s cloud capabilities.

Creating a Ditto Account

An App ID in Ditto functions like a tenant in the traditional cloud sense. It serves as a unique identifier for each distinct application environment, isolating data, and configurations within that specific context.

Creating a New App

Getting SDK Connection Details

Ditto's Data Browser and DQL Editor are graphical interfaces you can use to monitor, write, validate, and interact with your queries in a streamlined way.

Data Browser and Editor

Control access to your Ditto apps in the portal with role-based access control (RBAC).

Role-Based Access Control

The Portal Device Dashboard provides insights into devices that have been deployed with an application embedded with the Ditto SDK.  With the Device Dashboard, you can gather and store peer-to-peer sync and network details automatically rather than needing to continuously query Ditto for this data.

Using the Device Dashboard

Ditto offers an HTTP API to programmatically interact with transactional data generated in the mesh network and stored within Ditto Server.

Getting Started

The HTTP API is protected by an API key, passed in as an Authorization header. A number of other parameters are also permitted for each request.

Auth and Parameters

Execute a Ditto Query Language (DQL) statement against your data store. DQL is a powerful query language that supports complex queries, updates, and data manipulation. This endpoint serves as the primary interface for running DQL operations. See the comprehensive DQL guide for detailed syntax and examples.

A document consists of sets of fields that self-describe the data it encodes.

Fields

Ditto syncs and queries documents through a combination of collection names and document identifiers (`_id`). A collection is a grouping of documents, like *tables* in a relational database system but far simpler and more flexible.

Collections

Every document has an identifier field `_id`. The identifier field serves as the primary key for the document and can be either auto-generated or custom-assigned.

Identifiers

Relationships in Ditto are used to link related data items and organize them for easy lookup.

Relationships

The `REGISTER` type is the core building block of every app built on Ditto.

Register

An alternative approach to using a JSON object as a `REGISTER` to represent and organize data in a hierarchical structure within a document is to use a `MAP`.

This article provides conceptual information for the `ATTACHMENT` data type. For instructions on how to work with an `ATTACHMENT`, see *CRUD Operations* > [CREATE](../crud/create), [READ](../crud/read), [UPDATE](../crud/update), and [DELETE](../crud/delete).

Attachment

DQL Roadmap Functionality

At a high-level, queries operate on collections rather than individual documents. Filter, search, and retrieve specific information based on various criteria using Boolean operators, equal and unequal operators, comparison operators, and match operators.

Query Syntax (Legacy)

Ditto is a NoSQL database that organizes JSON-like documents into collections. Unlike JSON, with Ditto you can apply updates directly to the document, ensuring sync across all connected peers.

Documents and IDs (Legacy)

This article covers example mappings from Legacy Query APIs to DQL for basic CRUD operations as well as syncing data with the SDK.

Legacy-to-DQL Reference

Recently released, the Ditto SDK version 4.5 introduces the Ditto Query Language (DQL) — a simple SQL-like query language designed specifically for the features and capabilities of the Ditto platform.
