# Data model overview

In Planet Microbe, we aim to replace 'omic datasets in their borader environmental context. Therefore, any 'omic experiment is linked to one or several water samples. Biological and physio-chemical information may have been collected on these water samples. Larger context can be found exploring the sampling event information (cast, pump event...) and the cruise information.

Additionally, projects in Planet microbe allow to gather samples, sampling event and cruise that are part of the same project and produced by a unique PI.

This data model allows to retrieve any samples and 'omics dataset produced in a specific sampling event or cruise even if these samples were produced by different PIs.
