# Single Realm Architecture

### DataJet Object Structure

The following outlines the basic Object Architecture of a single DataJet Server installation, showing the relationships between:

- Home folder
- Mongo Database (used to store Object details, including database objects, reports, templates etc)
- DataSources (the location of raw data files, definition files, decode files etc)
- Repository (the folder containing all realms)
- Realm (the folder containing all project and processing data for the realm)
- Output (location of shared data exports for the realm)
- MyOutput (user's individual export folder)
- Project Folder (each project folder contains all the datafiles and indexes for the project)
