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. :)
multivalued data
The purpose of normalizing data in DBMS is to reduce the data redundancy and increase the consistency of data. a) Partial dependency: non-prime attribute ( field) depends on other non-prime attributes b) Functional dependency c) Transitive dependency
A DBMS offers quicker access to the data within the database, particularly with larger datasets. It also makes updates to the data easier.
It Occures When The Same data Dosent Matches Each Other In Various Relations(Tables) take an exp of this,suppose a publisher request for change his address is stored in a book as well as , if address of publisher is not modified in any of two field than the same publisher will have diff. address into diff. field .This is known as data inconsistency
dbms- database management systems............ it is a collection of interrelated data and the set of programs to access those datas....... it is used to meet the disadvantages of the file systems....... there are many disadvantages of filesystems....... lik,, data redundancy and data in consistency, difficulty to access data,integrity problems, atomicity problems............. dbms is quite complicated but better than file systems

DBMS is database management system and it stores data that are related. DBMS maintains data security and integrity as well.
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.
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.
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
DBMS stands for data base management system. DBMS is a collection of programs that enables users to create and maintain a database. The DBMS is a general purpose software system used to facilitate the process of defining, constructing and manipulating data bases for various applications. features of DBMS: 1.Data independence 2.Efficient data access 3.Data integrity & security 4.Data administration 5.Reduced application development time
Yes ,DBMS -data base management system
multivalued data
af
DBMS is short for database management system . DBMS is the collection of related records.
Traditional FPS and DBMS both are different from each other. In DBMS there is security of data as well as integrated data while this is not in FPS.
