# Data Collection Instance

:lock: DataCollectionInstance.**Show**

## Overview

A **Data Collection** is a reusable object that is associated to **Materials** via a **Data Collection Instance (DCI)** object. A **DCI** object holds the context for which the **Data Collection** was opened, along with the data posted during the lifecycle of the **DCI**.

The **DCI** page displays general information on the specific **DCI**. In addition, it enables you to perform all the operations that can be performed on a specific **DCI**.
