The Four Sublanguages
Captions available
The idea
Database work divides into four sublanguages: data definition for creating structures, data manipulation for changing contents, data query for asking, and data control for governing access.
In practice
A game studio's database sees all four in one day — new table, new scores, one report, one permission.
Where people slip
Different powers, deliberately separated.
