Parallel rating using DTOs

Parallel rating using data transfer objects (DTOs) offers even more performance improvement than parallel rating (using entities). Rating using entities saves and retrieves the entity instances in the database. Rating using DTOs offers improved performance because DTOs eliminate the overhead of accessing the database.

Note: Parallel rating using DTOs requires Guidewire Rating Management.

In the base configuration, parallel rating using DTOs is implemented in the commercial property line of business. There are some steps you must take to configure parallel rating using DTOs for commercial property.

You can extend parallel rating using DTOs to other lines of business.

Sample data

When parallel rating using DTOs is enabled, the small sample data set includes rate books and rate routines for DTO rating. These include DTO in their name or dto in their code. For example: the CP RTM Demo Rating DTO rate book and the BaseRate rate table definition with the code cp_coverage_base_rate_dto.

In Studio, the code that creates the sample data is in the gw.rating.flow.scenario.CPDTORateflowScenario class. This class creates the set of rate books and rate routines that uses DTO objects rather than entities in calculations and parameters. These rate books and rate routines provide same functionality as the sample data for commercial property that does not use DTOs.
