TIGUKAT was a novel object DBMS that was the subject of significant work between 1991 and 1999. TIGUKAT has a novel object model whose identifying characteristics include a purely behavioral semantics and a uniform approach to objects. The model is behavioral in that all access and manipulation of objects occurs through the application of behaviors. The model is uniform in that every component of information is modeled as a first-class object with well-defined behavior.
The uniformity aspects of Tigukat have been used to define a meta-model, query model, query optimizer, schema evolution, and temporal semantics as extensible components. That is, they are modeled as objects with well-defined behavior. This permits object-oriented development of these components within Tigukat and benefits from the advantages of an object-oriented approach.
Tigukat (tee-goo-kat) is a term in the language of the Canadian Inuit people meaning "objects". The Inuits, commonly known as
Eskimos, are native peoples of Canada with an ancestry in the Arctic Region of the country.
