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:
Application
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:
A sample data model for an application
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:A sample data model for a case type
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:A sample visual data model for a case type
Data object
A list of fields that contribute to a specific data object, for example,
Address, as seen in the following figure:A sample data model for a data object
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:A sample visual data model for a data object
For example: A data model for a loan management application might include a Mortgage
Request case type to handle loans. In addition to fields such as
Contact number, the case type depends on two other case
types, Appraisal and mySurvey, to collect
other necessary information as separate subprocesses. The main case type also relies on
two data objects: Address and Appraisers.
While case types manage the life cycles of processes, data objects group related data
into standalone entities that various case types in your application might reuse. With
the help of the visual data model for your application, you collect all the elements of
the process in one place for a more comprehensive analysis.
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.
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.
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.
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.
