Relational database
A relational database organizes data into tables that are linked together by shared keys, so related records can reference one another.
A relational database stores information in tables and defines relationships between them — for example, an orders table linked to a customers table so each order points to the customer who placed it. The relationships prevent duplication and keep data consistent.
In tools like Notion, relations connect one database to another so a single record can pull in and reflect data from related records. This mirrors the relational model used by traditional databases, made approachable without code.
Notion database
A Notion database is a structured collection of pages in Notion where each entry shares a defined set of properties and can be viewed in multiple ways.
Relation (Notion)
A relation is a property that links entries in one Notion database to entries in another, connecting related records.
Rollup (Notion)
A rollup is a Notion property that aggregates or summarizes data from records linked through a relation.
