Database Design and Management (Database)

A database is a structured collection of related data, stored in a way that allows easy access and manipulation.
Database design involves creating a plan for storing, organizing, and accessing data in a database.
Database management is the process of maintaining and controlling access to a database.
Database management systems (DBMS) are software systems that enable users and experts to create, manage, and control access to a database.
A database consists of related data items, typically organized into tables, enabling efficient data access and management.
Databases are crucial for managing large volumes of corporate data and information.

Defining Database

A datum is a singular piece of data, a raw fact.
Data represents raw facts, figures, measurements, and signals.
Information is data with context, enabling knowledge.
Data and information are key assets within digitally-driven organisations.
A database integrates and organizes related data for efficient management.
A database is a collection of related data stored in a structured manner.

Database Management Systems (DBMS)

A DBMS is a system used to create, modify, and control access to a database.
A DBMS helps multiple users and applications interact with a database concurrently.
A DBMS ensures data integrity and consistency by handling the data access process efficiently.
A DBMS provides tools and interfaces to access and manipulate database data safely and seamlessly.

Database Design

Database design involves specifying the database structure.
Design encompasses object relationships and components for a specific organization.
This process specifies the schema for a database from the perspective of an organization.
Design phases typically include requirements, conceptual, logical, schema refinement, physical, and security.

Database Categories

Databases are broadly categorized as relational, hierarchical, network, and object-oriented.
Each category offers a different approach to storing and managing data.

Database Application Areas

Database applications encompass a wide range of fields, like universities (records, payments, courses), banking (transactions), airlines (reservations).
They also include e-commerce (customer profiles, orders), human resources (employee data, salary), and manufacturing (production, inventory, orders).
Databases are crucial for managing and organizing data effectively across various applications.
