Page Comparison

When you create a data strategy, you select the options that control the types of reference data to release, the vendors to use, and the validations to apply for each gold copy composited security. You can define a series of data strategies for each reference data type, such as security, analytics, and so forth; however, you must not set up two data strategies that process the same security for the same reference data type. You can import Eagle default data strategies when you migrate security data strategies.

You can set up data strategies in Reference Data Center in the Data Strategy wizard. Here you can define the data strategy, specify the security criteria, select the field groups, define data sources to use, apply enrichments and select validation rules.
