A collection of related data sets organized for efficient access and management. Think of it as a structured storage for information.

A software system used to create, maintain, and manage databases. It provides tools for data storage, retrieval, and manipulation.

A complete system encompassing both the DBMS software and the actual data stored within it.

The process of transforming raw facts (data) into meaningful and useful information.

The ability to add new data records, update existing ones, and delete records from a database.

The ability to search, retrieve, and analyze data from a database based on specific criteria.

Storing and managing data for airline reservations and schedules.

Storing and managing financial information, customer data, accounts, loans, and transactions.

A database management system (DBMS) stores information about the database itself, such as its structure, data types, and relationships. This allows the DBMS to understand and manage the database without needing to know the specific details of the data.

The ability for a database to change its internal structure, such as data storage formats, without impacting applications that access the database.

A simplified representation of the database, hiding complex storage details from users and presenting a focused view of the relevant information.

Allowing different users to see customized views of the same database, focusing on the information relevant to their needs.

The ability of a database system to handle multiple users accessing and modifying the same data concurrently.

A mechanism used to ensure that multiple users accessing and modifying data simultaneously do not interfere with each other's operations, maintaining data integrity.

A common type of database application that focuses on processing transactions, such as financial transactions, online purchases, or booking systems.

A software system designed to manage and organize data in a database.

An organized collection of related data, structured for efficient access and management. Like a well-organized library, each piece of information has its place.

The process of creating a database with defined data types, structures, and constraints. Think of it as establishing the blueprint for your data's organization.

The act of physically storing the established database on a secondary storage device, making the data available for use. It's like putting your blueprint into action.

Actions like querying, retrieving, inserting, updating, and deleting data within a database. It's like accessing and manipulating the information you have built.

Managing multiple users' simultaneous access to the database while ensuring data integrity and consistency. It ensures that data is correct and avoids conflicts.

Security measures implemented to protect the database from unauthorized access. Like guarding your data from intruders!

The ability of a DBMS to take actions on data based on pre-defined rules. Like automatic reminders or alerts.
