A collection of many separate, unrelated files.

A system for storing and managing logically related data in a single, organized repository.

A software system that manages a database and provides tools for data access, manipulation, and security.

The physical components of a database system, like computers, storage devices, and network equipment.

Programs that make the database system work, including the operating system, DBMS, and applications.

The users of the database system, including administrators, designers, programmers, and end users.

Instructions and rules that govern the design, use, and security of the database.

The raw facts stored in the database, the actual information being managed.

Changes in data storage affect application program's ability to access the data.

Storing the same data multiple times in different locations.

Inconsistencies in data caused by redundancy.

Changes to existing data need to be made in multiple places, leading to inconsistencies.

Difficulty in adding new data due to data structure limitations.

Removing data unintentionally removes other related information.

Extensive programming, lack of ad-hoc queries, and complex system administration issues related to working with files.

Access to a file depends on its structure. Changes to the structure require changes to all programs using that file.

A form filled by sales staff, containing customer details.

Handles lease agreements and related documents.

A type of single-user database that runs on a personal computer.

A multi-user database designed for a smaller group of users, typically within a department.

A database where all data is stored in a single location.

A database where data is spread across multiple locations.

A database used for day-to-day business operations, often called an OLTP database.

A database designed for analysis and decision-making, housing historical data often used for business intelligence.

Data are raw facts, like numbers or names. Information is processed data with meaning, like an average score.

A shared, organized collection of data and metadata. Metadata describes the data itself, like the type of information it contains.

Databases improve decision-making by making data accessible, organized, and easily shared.

A software program that manages the database, controls access to data, and ensures its integrity.

Good database design ensures data is organized efficiently, easily accessible, and avoids redundancy.

DBMS allows multiple users and applications to access and use the same data.

DBMS controls access to data based on user permissions, preventing unauthorized access.

DBMS combines data from various sources into a unified view, preventing data silos.
