3.0: Released on July 30, 2023

Core features:

【Upgrade User Group Profile Analysis】
- Added a business dataset license that only supports User Group Profile Analysis, supporting customers to independently use the User Profile Analysis module + basic segment management capability of Sensors Analytics without purchasing data processing
- Added permissions: Customers only need to open the "User Group Profile Analysis" and "Business Dataset" corresponding permissions to use the functionality, simplifying the permission types.
- Added two methods to set rules for selecting people in the circle: "Filter Based on Existing Segments" and "Filter Based on Rules", to meet the diverse configuration needs of segments.
- User group profile templates have been migrated to the user profile analysis page. Administrators can search, create, edit, delete, and copy user group analysis templates in the analysis model to simplify operations.
- User group profile models can be added to the business dataset. Customers who have created analysis reports in the "User Profile Analysis" module can store, edit, update, and share the analysis reports in the "Business Dataset" after opening the complete version of the business dataset/user profile version of the business dataset module.
- Updates to user profile analysis operation logs: Customers can query operation logs to help locate issues.
- Migration of old profile reports: For customers who have upgraded to version 3.0 of user group profile analysis reports, we will migrate the old reports after the upgrade.
【Upgrade RFM】
- Added Sensors Analytics RFM analysis module license, supporting customers to independently use the user profile analysis module + basic segmentation capability of Sensors Analytics without purchasing data processing
- Added permissions: On the basis of opening the RFM License, customers only need the administrator to configure the "RFM Analysis" permission for other roles as needed, which can control the scope of use of the RFM analysis module.
- Updates to RFM analysis operation logs: Customers can query operation logs to help locate issues.
【Custom Query Added Data Permissions】
- Table-level permission control has been added to the data tables in custom queries. Users can only see and use the data tables for which they have permissions in the left catalog of custom queries. Tables without data permissions can apply for opening data permissions for accounts with the "Data Table Management" permission. For details on how to enable data table permissions, please refer to the [Data Table Management - Permissions] guide.

【Optimized Metric Management Module】
- Remove the dependency of the "Data Table" creation method in the Metric Management on the metadata permission points. Users with "Manage all metrics" or "Manage my metrics" permission points can use the "Data Table" to create metrics. Connect the data table permission of the "Data Fusion" so that users can only create metrics using the data tables they have permission to. Enrich the data table sources for creating metrics, supporting users to create metrics using six types of table sources: Item Table, Tag Table, Segment Table, SQL Intermediate Table, Detail Table, and Custom Table.
【Optimization Dimension Management Module】
- Remove the dependency of "Data Table" creation method on metadata permission points in dimension management, users with the "Manage All Dimensions" permission can use the "Data Table" to create dimensions; Connect the data table permission of [Data Fusion], users can only use the data tables they have permission to create dimensions; Enrich the source types of creating dimension data tables, support users to use six types of sources including item tables, tag tables, segment tables, SQL intermediate tables, detail tables, and custom tables to create dimensions.
【Optimize the relationship module】
- Synchronize the physical table relationships in [Data Fusion-Entity Relationship]. In other words, the relational relationships established between physical tables during the creation of entities in [Data Fusion-Entity Definition] will be automatically synchronized to the relationship list in [Metric Platform-Association Relationship]. Users can use such relationships in metric analysis. For the relationships synchronized from [Data Fusion-Entity Relationship], users can only view them in the relationship management module of the metric platform and cannot edit them. If editing is required, it can be done in [Data Fusion-Entity Relationship]. If a relationship is deleted from [Data Fusion-Entity Relationship], the synchronized relationship in the metric platform will also be deleted.
Integrate [Table Application Management] with [Data Fusion].
- Optimize the way to enable table scope in [Data Fusion], the function of enabling/disabling data table application in [Table Application Management] is unified in [Data Fusion].
- Support eight types of sources, including event table, user table, item table, tag table, segment table, SQL intermediate table, detail table, and custom table, to be synchronized and enabled in the metric platform.
- Connect the data table permission of [Data Fusion], users can check in [Table Application Management] whether they have the permission to build metrics, dimensions, and association relationships using data tables.
- The function of setting primary key in the original data table management is integrated into [Data Fusion].
