Based on the provided knowledge sources, I don't have enough specific information to answer which table Ory Kratos stores the traits like birthdate in the database. The knowledge sources don't contain details about Ory Kratos' internal database schema or table structure. However, I can provide some relevant information about how Ory Kratos handles identity traits: 1. Traits are part of the identity schema in Ory Kratos. They represent customizable fields for user profiles, which can include things like birthdate. 2. The identity schema is defined using JSON Schema, allowing you to specify custom fields for identities. This is described in the [Customize identity schemas](https://www.ory.sh/docs/kratos/manage-identities/customize-identity-schema) documentation. 3. Traits are stored as part of the identity object. According to the [Kratos API Reference](https://www.ory.sh/docs/kratos/reference/api), traits are included in the identity object, but the specific database table is not mentioned. 4. The traits are accessible through API endpoints that return identity information, suggesting they are stored in a way that's retrievable with the rest of the identity data. To get specific information about the database table structure, you might need to consult Ory Kratos' database schema documentation or source code, which are not provided in the given knowledge sources.
