STATICS versus DATA

Hello, folks!

Can someone explain me what the difference between STATICS and DATA?

My doubts is related to performance: memory allocated, acess in internal tables declared like STATICS, etc.

Thaks a lot!

I know how i can use both of them STATIC and DATA.

My doubt is about best practice.

There are some cases that i mustn't use STATIC variables? In some WEBAS configuration this statement can cause a bad performace?

Some OS doesn't work fine with STATIC variables?

Internal tables declared by STATIC have some problem to read data?

Thanks
