Database Overview

A database is an organized collection of data managed by a database management system (DBMS).
DBMS software enables interaction with end users, applications, and the database to efficiently capture, analyze, and manage data.
The combination of a database, DBMS, and applications is referred to as a database system.

Database Storage

Small databases can be stored on traditional file systems.
Large databases are often hosted on computer clusters or cloud storage solutions.

Database Design Considerations

Database design includes data modeling, representation and storage efficiency, query languages, security, and privacy.
Important aspects also involve distributed computing considerations, such as concurrent access and fault tolerance.

Database Management System Functions

DBMSs perform four main functions:
- Data Definition: Creation and modification of data organization definitions.
- Update: Inserting, modifying, and deleting data entries.
- Retrieval: Selecting data based on criteria and providing it to users or applications.
- Administration: User management, data security enforcement, performance monitoring, and data integrity maintenance.

Types of Databases

Relational databases emerged in the 1980s, modeling data in rows and columns within tables, primarily using SQL for interaction.
Non-relational databases, referred to as NoSQL, gained traction in the 2000s and utilize various query languages.

Database Models and Systems

The term "database" sometimes ambiguously refers to either the database itself or the associated DBMS.
A DBMS allows for specific data access while managing the organization of the data.
Database models dictate the principles adhered to by both databases and their DBMS.

Database Servers

Database servers are dedicated computers designed to run DBMS and related software.
They typically feature multiprocessor architectures, substantial memory, and RAID disk arrays for reliable storage.
Large transaction processing environments sometimes employ hardware accelerators connected to servers via high-speed channels.

Market Considerations

The extensive market for DBMSs influences computer and storage vendors to align product development with DBMS requirements.
Databases and DBMSs can be classified by database models (like relational or XML), operating environments (from server clusters to mobile devices), and query languages used (such as SQL or XQuery).
