## What is Directus?

::: tip Directus

Directus ([duh REKT iss](http://audio.pronouncekiwi.com/Salli/Directus)) is Latin for: _laid straight, arranged in
lines_.\
The broadest goal of our platform is to present data in a simple, orderly, and intuitive way.

**Directus is an Open Data Platform built to democratize the database.**\
This platform provides everyone on your team, _regardless of technical skill_, equal access to data and digital file asset
management, for any data model or project. First, link Directus to your desired SQL database and file storage adapter. After
that, Directus enables you to perform CRUD operations, create users, assign roles with fully configurable permissions, build
complex and granular queries, configure event-driven webhooks and task automation... _the list goes on!_

**Database Introspection & Abstraction**\
SQL flavors all come with slightly different data types and idiosyncrasies. Directus uses [Database Introspection](#how-it-works)
to read your database structure and create an abstraction layer to handle all the nitty-gritty details behind the scenes.
This technique works seamlessly with any major SQL database. It also lets you link Directus to your new or pre-existing database
or remove it anytime, with no impact on your existing data model. That means you'll never encounter vendor lock-in.

**The App and APIs**\
Once your database is introspected and abstracted, Directus dynamically generates REST and GraphQL API endpoints to manage
your data with granular control. You also get CLI tools for file management and a complete Javascript SDK.

The API and CLI power the no-code App. In other words, the App is just a GUI that provides no-code access to the API.
This architecture is how Directus democratizes the database and provides control to [the whole team](#who-s-it-for).

**Open-Source, Modular, Extensible, Scalable**\
At the highest level, Directus organizes its features and functionality into Modules. Each Module allows you to interact
with data in some specific way, such as data and content management, digital file asset management, drag and drop analytics
dashboard creation, or whatever. If you find Directus is missing something that your project needs, no problem!

Built entirely in Typescript, primarily on [Node.js](https://nodejs.dev) and [Vue.js](https://vuejs.org), Directus is
100% open-source, modular and extensible, ensuring your project never hits a hard feature ceiling. The platform scales
without issue, _and some Projects have hundreds of millions of users._

You can use it with any _(or many)_ stacks or frontend frameworks.

**Custom Configuration Options**\
Extensive configuration options are also available as global variables in the codebase. Developers can custom configure SSO
authentication method, caching details, default file storage location (local, S3, google, etc.) for digital assets, emails,
_and much more._

## How It Works

**Directus is installed as a _layer_ on top of your new or existing SQL database.**

The App and API dynamically _"mirror"_ your actual schema and content in real-time. This is similar to how technical
database clients (like _phpMyAdmin_) work. However, Database Introspection has many unique advantages:

- Absolute control over your pure SQL database schema.
- Complete transparency, portability, and security for your data.
- Allows importing existing databases, unaltered and without migrations.
- Direct database access and the full power of raw, complex SQL queries.
- Significant performance improvements through optimizations and indexing.

In contrast, other platforms typically use a predefined or proprietary _one-size-fits-all_ data model to store content .
That is not the case with Directus. Directus gives you direct access to your pure and unaltered data. That means you
have the option to bypass the Directus middleware (API, SDK, App) and connect to your data with proper SQL queries. This
effectively removes all bottlenecks, latency overhead, and proprietary access limitations.

## Who's It For?

**Directus lets the whole team work together and access data in one place.**

**Developers**\
Developers get a complete data connection toolkit with REST and GraphQL APIs, a JavaScript SDK, access to global variables
to customize configuration options, and direct command-line access to digital assets.

**Power Users**\
Data analysts and data scientists have in-app tools to query data, build out in-app analytics dashboards, and extract or
upload data in file format. Additionally, these users are still free to link other services and run raw SQL queries directly
on the database.

**Business Users**\
The no-code app is safe and intuitive enough to make data accessible to everyone, even the most non-technical users. Administrators
can create fully granular permissions for roles as well as individual users.

:::tip Directus Vocabulary

In order keep things simpler, _especially for the no-code users_, Directus uses friendlier names for many database terms
and technical concepts, including [Project](/getting-started/glossary/#projects) (database),
[Collection](/getting-started/glossary/#collections) (table), [Field](/getting-started/glossary/#fields) (column),
[Item](/getting-started/glossary/#items) (record), and [Type](/getting-started/glossary/#types) (datatype).

## When to Use It

**Directus can power any data-driven project and can be linked or removed at any time.**

Build, monitor or manage any data model or app you desire: IoT fleets, e-commerce, SaaS, business data analytics,
multi-channel content, _or anything else!_ If it involves SQL and digital files, you can link up Directus. With this in
mind, four broad use cases do emerge:

**Backend as a Service**\
An end-to-end data solution. Efficiently connects data, auto-generates exhaustive APIs for projects that scale, and provides
webhooks and task automation. Completely detached from the database, you're free to link and remove Directus anytime or use
any other service in tandem.

**Headless CMS**\
Remember, _content_ is just data from a database! Manage any omnichannel digital experience. Deliver file assets and data
across websites, apps, kiosks, digital signage... _the sky's the limit!_

**Internal Tool Builder**\
The whole team can build custom apps! Ditch the spreadsheet and quickly build back-office apps and admin panels for customers,
inventory, projects, marketing, _or anything else._

**Data Management and Analytics**\
Establish _a single source of truth_ for all data. Build no-code analytics dashboards to gain insights into company KPIs
and other metrics. Coalesce previously siloed department data.

## Why Use It?

**Directus is a simple, data-first solution to complex problems with no downsides.**

Directus was created in 2004 and has been slowly, iteratively improved on for a long time. The core team has carefully
thought through the app, beginning to end, and strives to make this platform is an all-benefit and no downside
experience. It is also plug-and-play, so you're free to link or remove it anytime, with zero impact on your data. You
have no vendor lock-in whatsoever, _your data is yours_. There are no artificial data limits _(e.g. limits on users or
roles)_.

Consider competing platforms in the four general use cases [mentioned above](#when-to-use-it). Due diligence to select a
viable solution from one of these categories can easily take six months to ensure the feature list, pricing,
scalability, migration options, etc.. all match the project in question. However, with Directus, that's not the case!
You can test it immediately on an existing database or build a new data model from scratch, _with no impact on your data
and no long-term commitments._

The following core principles guide this platform:

- **Pure** — No predefined or proprietary schema, with all system metadata stored separately.
- **Open** — Directus Core is public and open source, with no obfuscated or cloud-only code.
- **Portable** — The database can be exported or migrated anytime, so there's no vendor lock-in.
- **Limitless** — No artificial limits or paywalls on users, roles, languages,
  [Collections](/getting-started/glossary/#collections), or [Items](/getting-started/glossary/#items).
- **Extensible** — Every aspect of this platform is modular to avoid any hard feature ceiling.
- **Unopinionated** — Choose the stack, database, and architecture as you wish.
