A database system is a way of organizing information on a computer, implemented by a set of computer programs. This kind of organization should offer: * simplicity - an easy way to collect, access-connect, and display information;
* stability - to prevent unnecessary loss of data;
* security - to protect against unauthorized access to private data; * speed - for fast results in a short time, and for easy maintenance in case of changes in the organization that stores the information. Each subject in the common database is put in a structure or object which is called a "table." The database provides a way to connect or "query" the different subjects depending on the goal of the question. Most of the common databases use a standard query language or "SQL" (although there are less-common kinds of databases that use different ways of accessing the data). The first databases were developed in the early 60s in the US. Most commercial and non-commercial organizations use a database for storing their important information.
An ordered collection of information. Usuall this is organized into tables, so you might also define a database as a collection of tables (together with some other, supporting, data structures, such as indices and views, and perhaps some computer code).
The system database that contains descriptions of the data in the database is called the data dictionary or metadata repository. It stores information about the structure, definition, and organization of data elements within the database to help users and systems work with the data effectively.
Functions of a Database Management System: - Database Definition - Database creation (storing data in a defined database) - Retrieval (query and reporting) - Update(Changing the contents of the database) - Programming User Facilities for system development) - Database revision and restructuring - Database integrity control - Performance Monitoring
Database management system is a software system that creates,expands and maintains the database.

No. Database is a data itself, organized according to rules of database management system. And Database Management System is a software used to organize a database, and to acces it too.
The database life cycle refers to the process of designing, creating, implementing, and maintaining a database system throughout its entire existence. It typically involves stages such as requirements analysis, database design, implementation, testing, deployment, and ongoing maintenance and updates to ensure the database remains efficient and effective.
database management is a system
No, database is not an operating system. Database is a system used by websites or software to store data they use.
a collection of data is supplied by the database vendor. example: Oracle
1. A data definition language 2. A data manipulation language 3. A data dictionary
The databases that compose a database system are typically referred to as a "database schema." A schema defines the structure of the database, including the tables, fields, relationships, and constraints. It serves as a blueprint for how data is organized and accessed within the database system. Additionally, the entire system, including the database and the database management system (DBMS), is often referred to as a "database environment."
DML is a subset of SQL (Structured Query Language) that is used to insert, delete and revise records (or 'tuples') in a relational database. The precise definition of DML varies considerably with the database system with which it is associated.
