# Chunk and Index Data Model Objects

When you create a search index configuration, Data 360 creates two additional data model objects: a chunk data model object and an index data model object. These objects store the corresponding data and generated embeddings in Data 360.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: <strong>All Editions</strong> supported by Data 360. See <a href="https://help.salesforce.com/s/articleView?id=data.c360_a_dc_editions.htm&amp;release=264.0.0&amp;type=5" title="Data 360 is available in several supported Salesforce editions. Some Data 360 features also require additional licenses.">Data 360 edition availability</a>.</td></tr></tbody></table>

Each field that you supply a chunking strategy to is stored in the chunk data model object, from which Data 360 references the chunked data.

The generated vector embeddings and a unique identifier for each chunk is stored in the index data model object, from which Data 360 supplies search results.

Both chunk and index DMOs are Semantic type DMOs.

## Chunk and Index Data Lake Objects Data Categories

When you create a search index configuration, Data 360 creates two additional data lake objects: a chunk DLO and an index DLO.

Chunk DLOs are given the Content data category.

Index DLOs are given the Vector Embedding data category.

    The chunk data model object (CDMO) stores chunked content for each field from a chunked object.
