Overview
How DortDB translates every language into one formal algebra over a unified object representation.
Unified Object Representation
Items, tuples, and streams, the uniform internal representation that abstracts over heterogeneous data models.
Unified Algebra
Operator context, instantiation, plan visualization, and a tour of every operator group.
Operator Reference
Every operator of the unified algebra, with a plain-language description, signature, and formal semantics.
Language Mapping
How SQL, XQuery, and Cypher constructs are lowered into the unified algebra.
Optimization
The rule-based optimizer, the rewrites it applies, and how secondary indices are matched.
