Would PowerBI and other reports tools could query on Odoo Database (Accounting) fields?

'And other' is quite a vast question, but, in general yes, but it depends on your hosting environment. Self-hosted Odoo or hosting via odoo.sh on a dedicated server (shared odoo.sh hostings do NOT provide this option!), will allow you to access your database by the means of SQL from outside. The 'how', especially on self-hosted setups will require different steps based on your current network setup.

Also, utilizing 3rd-party modules or external connectors (i.e. for Odoo Online instances) are an option. See for example these posts related to Power BI

We understand that your team has been using Jet Reports extensively in the past, and you are now transitioning to Odoo for your business operations. It’s great to hear that you already have access to the API URL and key, which opens up possibilities for integrating external tools.

Regarding your question about using Jet Reports with Odoo, while Jet Reports is primarily designed to work with Microsoft Dynamics products, we can help explore alternative solutions to achieve similar reporting capabilities using your Odoo data.
