datumwise is an independent research project exploring central topics of our time around data, analytics and technology.
It is the work of Huayin Wang (research) and Irena Wang (engineering), open and independent.
Its work includes the Theory of Data, Analytical Governance, Frame-QL, and Columna — infrastructure for governed analytical service, open source under Apache-2.0.

Columna is a project of datumwise (datumwise.ai) — not affiliated with Datawise, datawise.ai, or columns.ai. Columna is not a data-cataloguing or documentation-generation product; it declares what data means, checks the declaration against the data, and refuses what the data cannot answer.
Not to be confused with Columnar (columnar.tech), an Arrow-native connectivity layer one letter from our name. They move columns fast; we govern what columns say. If anything, the two compose. More on the Ladder →
