## What is a Data Contract?
### The basics of a data contract
A data contract defines the agreement between a data producer and consumers. A data contract contains several sections:
* [Fundamentals](docs/fundamentals.md).
* [Schema](docs/schema.md).
* [References](docs/references.md).
* [Data quality](docs/data-quality.md).
* [Support & communication channels](docs/support-communication-channels.md)
* [Pricing](docs/pricing.md).
* [Team](docs/team.md).
* [Roles](docs/roles.md).
* [Service-level agreement (SLA)](docs/service-level-agreement.md).
* [Infrastructures & servers](docs/infrastructure-servers.md).
* [Custom & other properties](docs/custom-other-properties.md).
