A data model visually organizes the data in your application and displays the relationships among various data elements in a digestible way. The visual representation helps you understand data dependencies and make informed decisions as you expand your application's capabilities.
Professional application design and development relies on clear and comprehensive data models that constantly evolve to adapt to dynamic business requirements. Pega Platform provides the following levels of data model to meet that goal:
- An interactive block diagram that captures all case types and data objects
in your application. Relationships are clearly visible and the navigation is
intuitive. You can open data models for individual case types and data
objects directly from the application data model.
The following figure illustrates an example of an application data model:
- Case type
- A list of fields and references that contribute to a specific case type. The model might include data references, case references, and so on, as seen in the following figure:On the Data model tab, you can add further fields and reference data for use in your case types. You can also switch to the visual data model for your application, with the focus on the case type:
- Data object
- A list of fields that contribute to a specific data object, for example, Address, as seen in the following figure:On the Data model tab, you can add further fields to associate with the data object. You can also switch to the visual data model for your application, with the focus on the data object:
- Basic concepts in data modeling
Understanding the key components of the Pega Platform data model helps you define, manage, and reuse high quality data assets in your applications.
- Configuring a basic data object
Speed up application development by creating data objects that collect related information into reusable entities. By using data objects, you can simplify your data structure for easier reuse across interfaces.
- Fields as building blocks for data objects
By learning about the different types of fields that are available in Pega Platform data objects, you ensure that you can effectively capture and present information in your cases.
- Exploring the visual data model
Understand the relationships among case types, data objects, and fields in your application by using the data model visualization.
- Updating your data model
Maintain data integrity by updating your data model when changes occur.
- Data objects overview
Data objects define the logical data layer and hold data for your application. A data object simplifies the organization of the properties, data pages, transforms, and other elements your application needs to get the right data at the right time.
- Exporting data records
To get application data into an editable CSV file, create an export file.
- Adding fields
Use the following topics to define fields for your data object. For example, you can add choices to a picklist to control which options a user selects.
