Answer:
1) A DBMS provides mechanism to deal with this kind of data inconsistently while allowing users to access the data currently. A DBMS implements ACID (atomicity, duarabilty, isolation, consistency) properties to ensure efficient transaction management without data corruption.
2) A software system used to maintain relational database is a relationship database system(RBDMS). many relational database systems have an option of using SQL (structured query language) for quearing and maintaining the database.
3)The Primary Key constraint uniquely identifies each record in a table.Primary key must contain unique values, and cannot contain null values. a table can have only one Primary Key and in the table this primary key can consist of single or multiple columns (fields).
