SQL 2003 comes in multiple parts:

- 9075-3: SQL/CLI
- 9075-4: SQL/PSM
- 9075-9: SQL/MED
- 9075-10: SQL/OLB
- 9075-11: SQL/Schemata
- 9075-13: SQL/JRT
- 9075-14: SQL/XML
Part 1: 82 pages Part 2: 1267 Part 3: 405 Part 4: 184 Part 9: 501 Part 10: 402 Part 11: 296

Yes. Part 2 does not mention 'relational' or 'relation'; it does mention relationship but means how two tables are related or how SQL features are related. The most common match for 'relation' is 'correlation'. Part 1 is similar - I didn't check the rest but would not expect them to be any different.
