extension in a relation is set of tuples appearing in relation at any given instance .
it varies with time .it changes tuple are created ,destroyed and update
In database management systems, extension refers to the actual data values stored in a table, while intension refers to the structure of the database, including its schema, constraints, and relationships between tables. Extension represents the instances of the database elements, while intension represents the definition or blueprint of those elements.
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.
Database Management Systems, or DBMS, are software applications specially designed to interact with the user and other applications, as well as the database itself, to analyze data. All files in a software have file name extensions to identify their file types. For memory files .mem is the file name extension.
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.
The full form of DBMS is Database Management System.
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.

Malafied intension mean bad intension...eg.
ExtensionThe extension of a given relation is the set of tuples appearing in that relation at any given instance. The extension thus varies with time. It changes as tuples are created, destroyed, and updated.
Means bad intension eg illegal

Extension refers to the set of actual objects or individuals that a term or concept refers to. Intension refers to the defining characteristics or properties of a term or concept that determine which objects or individuals fall under that term.
The main intension is to sell the product in the market,to satisfy customer needs and earn profit ....

The distinction between database schema and database state is very important. When we define a new database, we specify its database schema only to the DBMS. At this point, the corresponding database state is the empty state with no data. We get the initial state of the database when the database is first populated or loaded with the initial data. From then on, every time an update operation is applied to the database, we get another database state. At any point in time, the database has a current state. The DBMS is partly responsible for ensuring that every state of the database is a valid state-that is, a state that satisfies the structure and constraints specified in the schema. The DBMS stores the descriptions of the schema constructs and constraints-also called the meta-data-in the DBMS catalog so that DBMS software can refer to the schema whenever it needs to. The schema is sometimes called the intension, and a database state an extension of the schema.
no, Java is not dbms.. Java is a programming language Dbms is database
