- Which three backups are there for database restoration? Where does each tier of backups fit in?Create a new database using phpmyadmin (or any other method you choose). The database should have at least two tables: One table should be able to store the username and password of users for session management. Insert one record in this table for use later in the project. The second table should be able to store the articles written by the user. The only information we need for articles is the author (which would be a user of the system), the title of the article and the content of the article. The content field should be able to store at least a thousand characters. Insert one simple record in this table for use later in the project H4Under server security, you can create additional Server Roles. F In simple recovery model, no differential backups are performed.
