...though.
Btw: If you're dealing with DNA strings only: You can compress a char into two bits and pack your data quite a lot. This will cut down the memory requirement by factor four over a naiive representation. Addressing becomes more complex, but the ALU of your CPU has lots of time to spend duri...
Should I use encodeURI or encodeURIComponent for encoding URLs?
....
encodeURI assumes that the input is a complete URI that might have some characters which need encoding in it.
encodeURIComponent will encode everything with special meaning, so you use it for components of URIs such as

What's best SQL datatype for storing JSON string?

IMAGE, VARBINARY(MAX) : IMAGE is deprecated just like TEXT/NTEXT, and there's really no point in storing a text string into a binary column....
So that basically leaves VARCHAR(x) or NVARC...
