Is it possible to access data in DataEase from outside DataEase?

Yes there are several ways to get access to DataEase data from outside of DataEase all depending on what you want to do. 

There is the DataEase server that give you a REST API to the data and also scripting language bindings like for Python and Node.js

If you tell me what you want to do specifically, I can give you a better overview of your options.

Is it possible for us to link into the data directly?

We use Power BI and this enables us to connect to SQL, Azure, etc

If you ask if DataEase have created a interface specifically for Power BI, the answer is no, but we have helped other customers with creating connections to other BI products.

From what I can see from a quick look at Power BI web pages, they support to use a Python script to deliver data. That can most likely be used for making a data provider for Power BI in Python by using the DataEase python library.

If you could provide me with a more specific use case, I can give you a more specific answer and tell if there are  better ways of connecting.
