If you want to see the data available from a specific source: * Select the source name from the list (e.g., Amazon Vendor Central).\ data_catalog_001.png\ The most frequently used tables for that source appear. * Select a visible table to see the data it contains, or select **See all** to browse a full list of tables for that source.\\ data_catalog_002.png 2. If you want to filter the data catalog by specific criteria, select a filter (e.g., E-commerce) from one of the following filter types:\\ data_catalog_003.png * **Categories** : Focus on specific types of data, such as e-commerce or DC inventory, to help you answer targeted analytics questions. * **Data Refresh Frequency** : See data based on how often Crisp checks for new data from the source. **Note** : The source data may be updated at a different frequency from the frequency with which Crisp checks for new data. For example, a report may be updated weekly from the source, but Crisp may check for data updates on a daily basis. * **Data Preparation Type** : Choose one of the following options to filter by the level of processing applied to the data: * Source— Tables that reflect the source system's structures as much as possible.\ **Note** : Crisp often has to do some transformations of source data, like column transposition and normalization, in order to provide tabular data. * Normalized— Tables cleaned and normalized by Crisp. * Denormalized— Tables cleaned, normalized, and then denormalized by Crisp. * Harmonized— Tables with data from multiple sources harmonized by Crisp to give you a unified analytics feed. For more information, see [Crisp harmonized data feed](/docs/support/articles-Data-catalog). * **Show Deprecated** (toggle): Choose whether or not to show data tables that have been deprecated.\ Once you select a filter, the list on the right side of the screen updates based on your selection. 3.
