Scalar Datatype Reference
Choosing proper datatypes to match the domain chosen in logical modeling is an important task. One datatype might be more efficient than another of a similar type. For example, you can store integer data in an integer datatype, a numeric datatype, a floating point datatype, a character type, or even a binary column, but these datatypes certainly aren’t alike in implementation or performance.
In this appendix, I’ll introduce you to all the intrinsic datatypes that Microsoft provides and discuss the situations where they’re best used. The following is a list of the datatypes I’ll cover. I’ll discuss when ...
