Adatbázistechnológia refers to the technologies and methodologies used for creating, managing, and utilizing databases. A database is an organized collection of structured information, or data, typically stored electronically in a computer system. Database technology encompasses the hardware, software, and processes that enable data to be stored, retrieved, and manipulated efficiently and securely.

Key components of database technology include database management systems (DBMS), which are software applications that act as an interface between users and the database. Popular DBMS examples include relational database management systems (RDBMS) like MySQL, PostgreSQL, and Oracle, which organize data into tables with predefined relationships. NoSQL databases, on the other hand, offer more flexible data models for specific use cases.

The development of database technology has been crucial for modern information systems, supporting applications ranging from e-commerce and financial services to scientific research and social media. It allows for data integrity, concurrency control, security, and efficient querying, making vast amounts of information accessible and actionable. Continuous advancements in areas like cloud computing, big data, and artificial intelligence further shape the evolution of database technology, addressing new challenges and opportunities in data management.
