The article and the comments are missing the most important thing.

For DDD don't use SQL as your database.

Postgress ( and eg. The excellent library martendb for dotnet) are perfect for this.

Dump ( or update) your object to the db and the ability to query some properties ( so you don't need an additional search service to query your data - https://martendb.io/documents/indexing/duplicated-fields.htm... )

Using SQL is going to give you a lot of unnecessary headaches when using DDD and trying basic crud.
