each column contains same type of data thus when you select a data type for a particular domain then DBMS will not accept any value of other data type.
Further information contributed by Ramona Maxwell. Please visit www.sqlsolver.com:
Domain constraints are a user-defined data type which enforces the integrity of the standard data types. A domain consists of all values permitted in a column. In constructing your database you would first select a standard data type such as VARCHAR or INT. You could then constrain or limit the data using NOT NULL, UNIQUE, CHECK, PRIMARY KEY or FOREIGN KEY. For example the CHECK constraint could limit INT data within your domain [column] to numbers less than 5000. You would thus define a custom data type using domain constraints.
In database technology, domain refers to the description of an attribute's allowed values. The physical description is a set of values the attribute can have, and the semantic, or logical, description is the meaning of the attribute.
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.
if we need a modifying ,sreach,delete a file so we need a DBMS
join by itself
YES
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
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.
so it role is basically to manage the database
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.
In database management system (DBMS), intension refers to the structure or schema of the database. It defines the overall design and organization of the database, including tables, columns, data types, constraints, and relationships. It serves as a blueprint for creating and managing the database.
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
For small-scale projects with minimal data storage requirements, using a DBMS may introduce unnecessary complexity and overhead. In scenarios with strict real-time constraints or extreme performance requirements, the additional processing time involved in interacting with a DBMS may not be acceptable. When the data is highly unstructured or varies significantly in format, a DBMS may not be the most efficient or effective storage solution.
A key is a set of attributes that uniquely identifies an entire tuple, a function dependency allow us to express constraints that uniquely identify the values of certain attribute.

Some advantages of relational database management systems (RDBMS) over traditional database management systems (DBMS) include data integrity through the use of constraints, normalization to reduce redundancy, support for ACID transactions, and standardized SQL language for data manipulation. RDBMS also offer scalability and flexibility for complex data structures and relationships.
A DBMS (Database Management System) is a software that manages databases and provides functionalities to store, retrieve, and update data. An RDBMS (Relational Database Management System) is a type of DBMS that stores data in a structured way using tables with relationships between them. RDBMS enforces the relational model, which allows for data integrity through constraints and supports SQL for querying data.
no, Java is not dbms.. Java is a programming language Dbms is database
