Entity Parent Class

Where can i find reference of different Parent class in the studio e.g. BaseUuidEntity, CategorizedEntity, StandardEntity, BaseReportEntity etc.?

You can find some information and recommendations on choosing base classes here: https://doc.cuba-platform.com/manual-6.1/base_entity_classes.html

Thanks. But I didn’t fine the info about CategorizedEntity or BaseReportEntity in the documentation. what is the specificity of those class?

CategorizedEntity is a base class for entities which can be separated by categories and hence have several sets of dynamic attributes.

BaseReportEntity is used internally in the Reporting base projects, do not use it as a base class for your entities.
