- High level & procedural
- Defines how to build relations
#### Data Manipulation Language
- Provides set of operations
- Data retrieval - query language
- ex. SQL
#### Closure
- Operations work on one or more relations to define another relation without changing the original
- Both operands and results are relations, output from one operation can become the input for another operation.
- This allows nested expressions.
