In SQL data consistency is that whenever a transaction is performed, it sees a consistent database. During the transaction, if the database is not consistent, then there are two reasons for it, which are as follows:
1-database failure (software or hardware failure)
2-multiple accesses
data consistency makes sure data integrity and vice versa.

Consistency constraints in dbms?
Consistency constraints in a DBMS ensure that data remains accurate and reliable throughout the database. These constraints can include primary key constraints, foreign key constraints, unique constraints, and domain constraints, all of which help maintain data integrity by enforcing rules that must be followed when inserting or updating data in the database. By upholding consistency constraints, the DBMS helps prevent errors and maintains the overall quality of the data.
What is concurrent schedule in dbms?
A concurrent schedule in DBMS refers to multiple transactions running concurrently without interfering with each other. This allows for improved performance and efficiency in handling multiple operations simultaneously. However, it requires careful management to ensure data consistency and avoid conflicts such as race conditions.

Is SQL DBMS or RDBMS?

What are three types of dbms?
Three types of DBMS (Database Management Systems) include relational DBMS, object-oriented DBMS, and NoSQL DBMS. Relational DBMS organizes data into tables with rows and columns, object-oriented DBMS stores data as objects and classes, and NoSQL DBMS handles unstructured and semi-structured data with flexible schemas.
What are the primary goals of dbms?
The primary goals of a database management system (DBMS) are to ensure data integrity, enable efficient data retrieval and manipulation, provide data security, and facilitate data consistency and concurrency control. Ultimately, the main objective is to manage and organize data in a structured and controlled manner to support the needs of users and applications.
How DBMS overcomeTFBS?
DBMS (Database Management Systems) typically overcome TFBS (Transaction Failure Before System) by using transaction management techniques such as ACID properties (Atomicity, Consistency, Isolation, Durability). These ensure that transactions are either fully completed or reverted to their original state in case of failure, maintaining data integrity. Additionally, DBMS often implement logging and recovery mechanisms to help recover the database state in case of unexpected failures.
What are rows in dbms?
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
What are the importance of dbms in industrial environment?

What is the purpose of dbms?
What is the purpose of dbms?DBMS is a software that organises the creation, storage and maintenance of Databases for end users.
