You can use the Setup workspace in Reference Data Center to create a data strategy by specifying information about the data strategy, including the name, general description, securities to process, fields to composite, data sources to use, and the enrichments and validations to apply during the securities compositing process. You can also audit the historical changes to data strategies.

Default Data Strategy

Once you create a data strategy, you can set it as the default data strategy. Each data category can have their own default data strategy. When a category has a default strategy set up, any securities that do not meet any other data strategy criteria are picked up and processed by the d default data strategy. This enables you to identify the securities that are not classified and to reclassify the securities appropriately.

Define the Data Strategy

You can define a data strategy that governs a specific subset of securities, including source hierarchy rules and other information about compositing data for these securities.

To define a new data strategy:

1. In the Setup workspace, in the left navigation, click Data Strategies.
   You see the Data Strategy workspace with the list of available data strategies. Values include:
   - Analytics
   - Exchange Rate
   - Issuer

   - Issuer Ratings
   - Prepayment Time Series
   - Price
   - Ratings

   - Variable Rates
2. Click Create New and select the data type from the drop-down list.
