The term integrity means to correctness and completeness of the data in data base. A relational data base is collection of related table. Table contains various information. Tables are connected by the foreign key relationship. When the contains with the certain command, insert, delete, update.The integrity of the data can be loss in many different waves.

What are rows in dbms?
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
How does DBMS reduce data redundancy?
DBMS stands for database management system. DBMS reduce data redundancy as it checks if the data is duplicate and if duplicate then store it as a single record.
How does DBMS solve problems in financila institutions?
Database Management Systems (DBMS) solve problems in financial institutions by providing a structured way to store, manage, and retrieve vast amounts of financial data efficiently. They ensure data integrity and security, which is crucial for protecting sensitive financial information. Moreover, DBMS facilitate real-time data analysis and reporting, enabling institutions to make informed decisions quickly and comply with regulatory requirements. Overall, they enhance operational efficiency and support customer service through better data management.
Sample of DBMS?
SAMPLE DBMS includes Oracle, DB2, MS Access, MS SQL SERVER, PostgreSQL, MySQL, Sybase.
How Armstrong rules are complete or sound in dbms?
Armstrong rules are complete or sound in dbms by clarifying the types of situations which need to be achieved and done.
What is integrity problem in dbms?
Integrity problems in a database management system (DBMS) refer to issues such as data inconsistencies, duplicates, or inaccurate information that may arise due to violations of data integrity constraints. These constraints ensure the accuracy and validity of data stored in the database by enforcing rules such as unique values, referential integrity, and domain constraints. Failure to maintain data integrity can lead to errors, data corruption, and compromised reliability of the information stored in the database.
What is a Multi-user DBMS Architecture?
A Multi-user DBMS Architecture is one big system of users and queries. The use of these are to over look and execute plans safely and does not violate and integrity constraints.
Consistency constraints in dbms?
it describes the instance of one entity is associated with each instances of an entity depending upon the range of cardinality constraints are two types they are minimum cardinality maximum cardinality
What ensures the value of the foreign key matches another tables primary key?
It is the DBMS that ensures the value of the foreign key matches another table's primary key when referential integrity constraints are enabled within the DBMS

Various integrity rules in a DBMS?
Three basic types of database integrity constraints are:Entity integrity, not allowing multiple rows to have the same identity within a table.Domain integrity, restricting data to predefined data types, e.g.: dates.Referential integrity, requiring the existence of a related row in another table, e.g. a customer for a given customer ID.
What does an DBMS do?
DBMS is database management system and it stores data that are related. DBMS maintains data security and integrity as well.
How does SQL allow implementation of the entity integrity and referencial integrity constraints what about general integrity constraints?
sql allow their implementation using various sql commands
What are roles and structural constraints in DBMS?

Is there any difference between integrity and correctness of data in DBMS?
Integrity refers to the structure of the data and how it matches the schema of the database. Correctness could refer to either the integrity of the data or its accuracy (for example, a phone number being incorrect).
Which units of a dbms responsible for structure integrity of a database?
