Is the ITTIA database free for the STM32?

[toufik_iddou]

Hi Community

I'm working on a project with stm32F407VET6, and I need a database for storing data. I found the ITTIA DB, and I install it from stm32 cube ide in the middleware categories (FreeRTOS support) but when I read the documentation in the official site, I read that it's not free, but I install it in stm32 normally.

so, I need to know if ITTIA is free for stm32. and if not, Is there a free database for the stm23?

thanks.

ITTIA is not a open source project and the web page only tells "free trial" so I assume you need to buy for the final product.
