SQL ET POSTGRE 4.19 : Deleting data from a table

Deleting data from a table is a common operation in database management. It consists of deleting records from a table, whether for cleaning, maintenance or security reasons. However, it is important to be aware that deleting data can have consequences for the integrity of the database. This can lead to referencing errors or inconsistencies in the remaining data. It is therefore important to take certain precautions before deleting data, including making a backup of the database and checking the relationships between tables. In terms of SEO, deleting data can have an indirect impact on the SEO of a website. If the deleted data was linked to pages indexed by search engines, this can lead to 404 errors and a lower quality of user experience. It is therefore important to carefully manage the deletion of data to avoid any negative impact on the natural referencing of a website
