# Data Factory

> Manage all form data sources of the current app in one place, including Datasets, View Tables, Cross-app Data Retrieval, Data Sources, Data Cards, Data Services, and Data Preparation.

The following table describes each data source management capability in detail:

| **Name**                                           | **Purpose**                                                                                                                                                                                                                                                                             |
| -------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [**Datasets**](/yida/app-admin/roe3o1)             | Manage all single-table data sources, view tables (multi-table associations), data preparation (big-data offline solutions), and cross-app (form) data sources of the current app in one place. Datasets serve as YiDA's standard data control unit for data interconnection scenarios. |
| [**View Tables**](/yida/app-admin/oim554)          | View tables preprocess existing form data through single-table or multi-table associations, and also support intermediate table mode to strengthen data processing. Scenarios such as report visualization and form linkage can call data from view tables directly.                    |
| [**Cross-app**](/yida/app-admin/btrtnt)            | Also known as cross-app data retrieval. Call form data from other YiDA apps within the current app to enable data interconnection across YiDA apps.                                                                                                                                     |
| [**Data Source**](/yida/app-admin/duy0wi)          | A data source describes where data comes from. YiDA supports managing and maintaining data sources such as files and databases.                                                                                                                                                         |
| [**Data Cards**](/yida/app-admin/cpkmxvpgchx339qq) | A new data visualization carrier. Unlike reports with a complete analytical pipeline, data cards quickly combine fragmented, scenario-based charts for use in YiDA portals. Cards also come with built-in broadcast capabilities that sync data to groups as snapshots.                 |
| [**Data Services**](/yida/app-admin/fw9qtv)        | Data services process datasets by selecting specific fields and converting them into API services. They can currently only be consumed within Card nodes of the integration & automation / workflow designer.                                                                           |
| [**Data Preparation**](/yida/app-admin/ykemo6)     | Before analysis and use, clean, merge, and transform raw data to aggregate scattered data into standardized datasets, supporting visual analysis and data-driven decision-making.                                                                                                       |
