Confused about tables name are case-insensitive

Hi everyone,

I have a question about database. I know Silverstripe default uses table name as UpperCamelCase
But is there any problems we will get if we use table names are lower cases?

In my case, our system seems still work well

But I’m not sure for all cases. Sample, dev/build will run too slow or lose data ???

We got a trouble for the last time deployment to prod. Some data was lost but I don’t know exactly what is reason.

So, if anyone can help then should be very beautiful.

Thank you so much!
