In InfluxDB, a point represents a single data record, similar to a row in a SQL database table. Each point:
- Has four components: a measurement, a tag set, a field set, and a timestamp.
- Is represented by one row in [line protocol](/v2.0/reference/line-protocol/).
- Is uniquely identified by its series and timestamp. In a series, each point has a unique timestamp. If you write a point to a series with a timestamp that matches an existing point, the field set becomes a union of the old and new field set, where any ties go to the new field set.

If you write a point to a series with a timestamp that matches an existing point, the field set becomes a union of the old and new field set, where any ties go to the new field set.
