# ActiveFacts::Compositions
Fact-based schemas are always in highly normalised or *elementary* form.
Most other schemas are composite (object-oriented, relational, warehousing, analytical, messaging, APIs, etc).
A *Composition* is a representation of the two-way mapping between an elementary schema and the composite schemas.
This gem provides:
* an API for compositions,
* several compositors which create Compositions - O-O, Relational and Data Vault and
* some generators which emit various kinds of output (Ruby, SQL) etc, for composed schemas.
This gem builds on the Fact Modeling Metamodel and languages of ActiveFacts.
