    A table with multiple fields (ID_AMIS, NAME, FIRST NAME ... etc) which contain various information are called records. The field is said ID_AMIS primary key. The value of a primary key can not be duplicated - There can be several ID_AMIS with the value 1 for example. For example, one might take the NAME fields as primary key. However, this would have been a problem if several people have the same surname. This key allows you to reference the row in the table.

    The constraints allow to verify the validity of data. The constraints can prevent the inclusion of incorrect data. For example, an invalid date. Inserting Null in a field not accepting this value. Finally, in the case of using foreign keys, referencing data not available. Connections to a database are subject to authentication. As a general rule to connect to a database, you must have the IP address or the name of the server hosting the database, the name of the database to which you want to connect, the user of the database having the right to connect to the database and the password of the user with the right to connect to the database.
