We have released a new version 2.2.0 with the following major updates:

1. ER Diagram for Cube Designer​

We have added the ER diagram feature to the cube designer. You can now view the data relationship model of cubes through the ER diagram, including fact tables, dimensions, measures, and relationships. This allows you to intuitively understand the data structure of cubes, facilitating data modeling and analysis.

2. Support for SAP HANA Database​

In this version, we have added support for the SAP HANA database. You can connect to the HANA database by configuring an HANA data source and create HANA semantic models. This enables direct multidimensional data analysis on the data from the HANA database within the Metad analytics platform.

3. Added Support for LangChain Framework​

In this version, we have introduced LangChain for the implementation of AI Copilot Commands' agents. When we input commands, the copilot parses the command and uses the LangChain Agent to execute the corresponding operations. Since behind the support for LangChain commands there are corresponding Agent implementations, we can configure different Agents to support different commands, thus giving commands more intelligent decision-making capabilities.
