Decisioning Service decisioning

Adobe Experience Platform Decisioning Service provides the ability to programmatically and intelligently select the ‘Next Best Experience’ from a set of available options for a given individual, deliver them to any channel or application, and perform reporting and analysis.

A prebuilt rich data model enables the use case of “Next Best Offer” decisioning in a channel agnostic way.

Key features

Business object repository
A repository driven by JSON schema models allows a developer to create, read, update and delete a variety of business objects. The repository provides general purpose, expressive query APIs as well as schema aware search.
Repository containers
Within the business object repository a developer may isolate their concerns around projects, business or organizational units, or around life cycle stages of a project (for example, in development and integration, staging, or for live production use). Those isolations are called repository containers.
Roles and permissions
Using the Admin Console, an organization can create and manage profiles to grant targeted access to resources by type, access operation, and container. Users can be added to those access profiles and effective access privileges are automatically computed from those policies.
Prebuilt offer object model
Without the need to first build a data model, a Platform developer can leverage prebuilt JSON schemas and relationships to create an offer catalog, define decision rules and constraints, and assemble offer collections for decisioning.
Decision rules based on profile and non-profile data
A tight integration with the Real-Time Customer Profile allows a developer to create decision rules that leverage Profile data. Not only can decisions be made using profile attributes but also based on the experience event history of a profile and based on business entities unrelated to a user identity (e.g. traffic conditions, product inventory). Any Experience Data Model (XDM) entity for which a schema exists in the Schema Registry can be used for the decision rules. Rules are first class entities and can be reused for any of the decision options and activities.
Ranking and capping
Decision options that fulfill all eligibility and other constraints for a given user are ranked and the best option is selected. Additional per user and global capping constraints can be used to limit the exposure of the available options, thus enabling personalization with resource constraints and user fatigue in mind.
Decisioning REST APIs
The Decisioning Service can be invoked using a simple REST API to get the Next Best Offer for a given individual. A metrics API can be used to check real-time offer proposition and capping values.
Streaming Decision Events into Data Lake and Query Service
The Decisioning Service auto-creates datasets to stream all XDM Decision Events automatically into the Data Lake. The datasets are then available for analysis and reporting using Query Service.
Developer enablement
Self service opt-in with documentation on Adobe I/O including tutorials for various topics.

Known issues

  • The offer data model is not exposed through the Schema Registry and can therefore only be extended in limited ways. The model schema has built-in structures to allow the attachment of custom data. In the future, you will be able to extend a base XDM model class to define your own custom decisioning domains.
  • You must be provisioned with the Offer Management domain model and users and integrations must be managed in this product context.

Query Service query

Query Service provides the ability to use standard SQL to query data in Adobe Experience Platform to support many different analysis and data management use cases. It is a serverless tool which allows you to join any datasets in the Data Lake and capture the query results as a new dataset for use in reporting, Data Science Workspace, or for ingestion into Profile Service.

You can use Query Service to build data analysis ecosystems, creating a picture of consumers across their various interaction channels. These channels might include:

  • Point-of-sale system
  • Web
  • Mobile
  • CRM system

Key features

Query editor
Use a web-based tool to write, validate, test, and execute queries. It includes a console for detailed information on the execution of queries, as well as the ability to preview query results.
Dataset creation
Create datasets on Experience Platform via standard SQL syntax.
Adobe-defined functions
Leverage shortcut functions for common tasks like identifying sessions or setting attribution.
BI tool connectivity
Use the PostgreSQL (Postgres) drivers found in common BI tools to connect to Query Service to create reports and visualizations. Supported tools include: Tableau, Power BI, and Looker. Find authentication information on the Credentials tab.
Database management tool connectivity
Connect Aqua Data Studio or DB Visualizer to Query Service for data exploration and dataset creation functionality. Query Service also supports connectivity from R Studio. Find authentication information on the Credentials tab.
Command line query tool
Connect PSQL to be able to run queries from the command line.
Query Log
Keeps a history of queries executed by Query Service and enables you to find prior SQL for editing, execution, or for creating a dataset out of the results.
Query scheduling API
Schedule queries for recurring execution via this API.

Known issues

  • Query Editor shows a sample of 100 rows of the results for your queries. In order to persist the complete result set, use the dataset creation capabilities from the Query Log.
  • Near-term releases will add support for Views and a UI for applying schedules to queries.

For more information about Query Service, see the product documentation.

Experience Data Model (XDM) xdm

Standardization and interoperability are key concepts behind Experience Platform. Experience Data Model (XDM), driven by Adobe, is an effort to standardize customer experience data and define schemas for customer experience management.

XDM is a publicly documented specification designed to improve the power of digital experiences. It provides common structures and definitions for any application to communicate with services on Adobe Experience Platform. By adhering to XDM standards, all customer experience data can be incorporated into a common representation delivering insights in a faster, more integrated way. You can gain valuable insights from customer actions, define customer audiences through segments, and use customer attributes for personalization purposes.

XDM is the mechanism that allows Experience Cloud, powered by Adobe Experience Platform, to deliver the right message to the right person, on the right channel, at exactly the right moment.

The methodology on which Experience Platform is built, XDM System operationalizes Experience Data Model schemas for use by Experience Platform components.

New features

JSON Schema constraints
The following datatypes now have additional options in the user interface to define constraints: string - min/max length, pattern, default value, formats (as defined in JSON Schema draft-6) and double - min/max, default value.
Custom $id
You can now provide your own $id value when creating resources in POST requests.
Schema Registry performance improvements
Optimized union schema generation, and enhanced schema caching to greatly improve API response times.

Bug Fixes

  • Moved the identityMap field out of context/profile and into its own schema field group to make defining identities more intuitive.
  • Patched all existing schemas based on context/profile with context/identitymap.
  • Fixed error message when no version is supplied.
  • Fixed bug where Schema Registry was giving random responses for profile union schema calls.
  • Fixed bug where union schemas were not displaying the correct fields in Schema Registry.
  • Fixed bug where identity descriptors were occasionally not able to be created with valid namespaces.
  • Fixed dereference issue if an object uses properties instead of allOf.

Known issues

  • Cannot extend a Platform-supplied field group by adding a field.
  • Descriptors are not deleted when a field group is removed from the schema composition.
  • Unable to create an enum field with no labels.

To learn more about working with XDM using the Schema Registry API and Schema Editor, please read the XDM System documentation.

Segmentation Service segmentation

Segmentation Service defines a particular subset of profiles from your Profile store, describing the criteria to distinguish a marketable group of people within your Profile store. Segments can be based on record data (such as demographic information) or time series events representing customer touch points with your brand.

For example, in an email campaign focused on running shoes, you could use an audience segment of all users who searched for running shoes within the last 30 days, but did not complete a purchase. Another example could be using a segment to target site content so that it displays only to visitors who belong to a certain tier of your rewards program.

New features

Relative time rules
You can now choose rolling time windows such as 14 days ago, 3 to 5 hours ago, etc.
XDM field summaries
For Attributes on the left-rail, summaries are now available providing a view into your underlying data.
Left-rail search
Improved search capabilities for the segments portion of the left rail.
eVar friendly names
Improved support for friendly names, allowing you to see more easily what information is captured within custom events and dimensions from Adobe Analytics.
Merge policy support
You can now choose which merge policy to apply to their segment definition using a simple dropdown.

Bug Fixes

  • Fixed an intermittent issue causing slow loading of the attributes and events building blocks in the left-rail.
  • Fixed a bug which caused the estimator to return “NaN” response.
  • Fixed an error where some fields were opening the incorrect rule building canvas.

Known issues

  • None.
