Andmebaasihaldus, often referred to as Database Management, is the process of organizing, storing, retrieving, and managing data within a database. It encompasses a range of activities and technologies designed to ensure data integrity, security, and accessibility. The core of database management lies in the use of a Database Management System (DBMS). A DBMS is software that allows users to interact with databases, enabling them to create, read, update, and delete data.

Key functions of database management include data definition, which involves specifying the structure and relationships of data; data manipulation, which covers operations like inserting, modifying, and deleting records; and data control, ensuring data security, concurrency, and recovery. Effective database management is crucial for businesses and organizations that rely on data for decision-making, operations, and customer service. It helps prevent data loss, corruption, and unauthorized access, while also optimizing performance for efficient data retrieval.

Different types of databases exist, such as relational databases, NoSQL databases, and graph databases, each suited for different data structures and access patterns. The choice of database and management system depends on the specific requirements of the application and the nature of the data being handled. Professionals in this field, known as database administrators (DBAs), are responsible for the overall health, performance, and security of database systems.
