Each row represents a single entity or data subject. Data are stored in the same row if they are associated with the same subject. Data for different subjects should be stored in separate rows. Rows are denoted by means of one of [PEP's identifiers](Pseudonymization#identifiers-in-pep). A new row is created by storing data into a row with a previously unused [participant identifier](https://gitlab.pep.cs.ru.nl/pep-public/user-docs/-/wikis/Pseudonymization#participant-identifier).

Columns are used to split data into conceptual units. Different types of data or different measurements should be stored in different columns. Columns are referred to by name, and the name is determined when the column is created. Only members of the "Data Administrator" role can create columns and perform other [administrative tasks](Administration) on them.

A major difference with traditional data(base) storage systems is that no separate column should be used to store a [fixed row identifier](https://gitlab.pep.cs.ru.nl/pep-public/user-docs/-/wikis/Pseudonymization#traditional-fixed-identifiers). Rows are instead referred to by means of PEP's [polymorphic identifiers](https://gitlab.pep.cs.ru.nl/pep-public/user-docs/-/wikis/Pseudonymization#identifiers-in-pep).
