What does SDC mean, and what is it?

SDC is the numbering system for published codes.

The SDC numbering system consists of 10 randomized numeric digits starting with 1000000000 and ending with 9999999999. Each SDC number is uniform. SDC numbers are not recycled if they are removed, and are not changed if a code is updated as long as its meaning remains the same.

Every SDC definition (such as a tank) has a code page, also referred to as the SDC page. SDC stands for "SKYDB Definitions Code".
