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.

what do u mean by lossiess join in dbms
multivalued data
save point saves the dbms and check point simply check the database thats it simple
When a Database Management System (DBMS) flags a deleted record, it typically marks the record as deleted without physically removing it from the database. This process allows the system to reclaim space later during maintenance operations, such as a vacuuming or compaction process. Flagging also allows for potential recovery of the record if needed, maintaining data integrity and consistency. Ultimately, the flagged record remains accessible for certain operations until it is permanently purged from the database.

DBMS stands for Database Management System. It is software that enables the creation, manipulation, and administration of databases, allowing users to efficiently store, retrieve, and manage data. DBMS provides tools for data organization, security, backup, and multi-user access, ensuring data integrity and consistency. Examples include MySQL, Oracle, and Microsoft SQL Server.

A subsystem of a Database Management System (DBMS) refers to a specialized component that performs a specific function within the overall architecture of the DBMS. Common subsystems include the Storage Management subsystem, which handles data storage and retrieval; the Query Processor, which interprets and executes database queries; and the Transaction Management subsystem, which ensures data integrity and consistency during concurrent operations. Each subsystem works together to provide the functionality and reliability expected from a DBMS.
no, Java is not dbms.. Java is a programming language Dbms is database
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.

In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
