Data mapping

<p>In <a href="/facts/Computing/Kghtm9fX">computing</a> and <a href="/facts/Data_management/Cykeqxc7">data management</a>, data mapping is the process of creating <a href="/facts/Data_element/jtyoAIAd">data element</a> <a href="/facts/Map_(mathematics)/FABF1l2f">mappings</a> between two distinct <a href="/facts/Data_model/j1YyzpJ3">data models</a>. Data mapping is used as a first step for a wide variety of <a href="/facts/Data_integration/BU47JR28">data integration</a> tasks, including:
</p>
<ul><li><a href="/facts/Data_transformation/gjQCKFIa">Data transformation</a> or <a href="/facts/Data_mediation/gjQCKFIa">data mediation</a> between a data source and a destination</li>
<li>Identification of data relationships as part of <a href="/facts/Data_lineage/cKtPUrde">data lineage</a> analysis</li>
<li>Discovery of hidden sensitive data such as the last four digits of a social security number hidden in another user id as part of a data masking or <a href="/facts/De-identification/etokaj8q">de-identification</a> project</li>
<li><a href="/facts/Data_consolidation/Cykeqxc7">Consolidation</a> of multiple databases into a single database and identifying redundant columns of data for consolidation or elimination</li></ul>
<p>For example, a company that would like to transmit and receive purchases and invoices with other companies might use data mapping to create data maps from a company's data to standardized <a href="/facts/ANSI_ASC_X12/yVMzQ1zs">ANSI ASC X12</a> messages for items such as purchase orders and invoices.
