Description

Data source is a third-party information system, data from which is subsequently used by Unidata platform as input. Each data source has its own level of trust (weight) which affects the priority of some data over others when you load data, process duplicate data, etc.

How to Create/Delete

To create a data source:

  1. Click the Create button at the bottom of the list of data sources.
  2. The action will create a new data source. The data source properties will be displayed in the main working area of the screen.
  3. Fill in the data source properties:
    • Name. This is a logical name. Once saved, the name cannot be changed.
    • Description: An arbitrary description of the data source.
    • Weight: Source weights affect the automatic consolidation of duplicates, whereby versions obtained from sources with higher weight become reference records. Depending on the quality and level of trust, the source can be assigned a weight from 0 to 100. The weight of the data source can be overridden for a specific entity or entity attribute.
    • Custom properties. A list of parameters (the “name” – “value” pair) that contain additional text information. Parameters can be referenced by custom extensions, and parameters can also contain non-standard information from external systems.
  4. Save changes, if necessary. Click “Save” in the upper-right corner of the screen. If filling errors are detected during saving, a corresponding message will be displayed on the screen.

To edit a data source:

  • Select the required data source from the list of sources.
  • Make the required changes. The “Name” field is not editable.
  • Save the changes. Click “Save” in the upper-right corner of the screen.

To delete a data source:

  • Click the Delete button located in the upper right corner of the screen.
  • Confirm the changes.
