Data\Curve Tables VS Database(SQLite etc.) for RTS game

Hello Community!
I want to make a simple RTS game. Therefore I’ll need to store a lot of data about the game processs and so on. But I don’t know which method choose to keep all of these data or get them fast. As I pointed in the topic, I choose between default UE4 methods (Data/Curve Table) and others Database system which I can integrate in UE4 or use in C++/BP.
What by you opinion better to use for RTS game ( and if possibly: why it is? ).
Thank you a lot.

Hope this plugin can help you.

Data tables.

A simple Google or Excel sheet is much easier to create, maintain, and import than an entire SQL backend. UE4 also comes with built in support for this workflow. Using a database is probably over-engineering in your usage case.
