# Relations and schemas

Relations are first-class TendBase data. Connect records to people, projects, decisions, dates, sources, and other records when the connection will help later recall or analysis.

Use typed, directional relations. Reuse an existing relation type when its meaning matches. Do not invent a new schema for every write. TendBase can infer versioned lenses over stored objects, but the agent still decides what each object and relation means for the user's request.
