Extending the Data Model
Data for the building blocks is stored in database tables that are defined by Data Shapes in ThingWorx Composer. This data model can be extended to add business-specific data to the model that is not provided out-of-the-box. This is accomplished in the following ways:
• Add custom properties to existing data model entities by updating the <entity>_AP Data Shape associated with the entity. For more information, see Adding Custom Properties to Data Model Entities.
• Add new entities to the data model by creating custom Data Shapes and the managers and services to manage them. For more information, see Adding Custom Entities to the Data Model.
• Create custom managers to manage (create and update) the database tables for your own custom entities. For more information, see Creating a Custom Manager.
