# System builds

The **System Builds** screen is where you turn your mapped data into an Orbit system.

From here you can:

- **Define a system**: Choose the tables to include and the relationships between them. See [Defining a system](<https://help.apteco.com/en/orbit/connect/system-builds/defining-a-system/index.md>).
- **Set table options**: Nominate people, contact, and response tables to make your system campaign ready. See [Table options](<https://help.apteco.com/en/orbit/connect/system-builds/table-options/index.md>).
- **Add lookup data**: Join extra data, such as geodemographic data, using one-to-one and many-to-one relationships. See [Additional relationship types](<https://help.apteco.com/en/orbit/connect/system-builds/additional-relationship-types/index.md>).
- **Organise folders and variables**: Arrange how your variables appear once the system is built. See [Folder structure](<https://help.apteco.com/en/orbit/connect/system-builds/folder-structure/index.md>).
- **Build a system**: Get your system ready to deploy, and review the results. See [Building a system](<https://help.apteco.com/en/orbit/connect/system-builds/building-a-system/index.md>).
- **Schedule builds**: Rebuild and optionally deploy your system automatically. See [Scheduling a system build](<https://help.apteco.com/en/orbit/connect/system-builds/scheduling-a-system-build/index.md>).
- **Deploy a system**: Make your system available for dashboards, analysis, and campaigning in Orbit. See [Deploying a system](<https://help.apteco.com/en/orbit/connect/system-builds/deploying-a-system/index.md>).
