Andmebaasihaldus

Andmebaasihaldus, often abbreviated as DBMS, refers to the software system that enables users to store, retrieve, define, and manage data in a database. It acts as an interface between the database and the end-users or application programs, ensuring data is organized, accessible, and secure. Key functions of a DBMS include data definition, data manipulation, data security, and data integrity.

The core purpose of a DBMS is to provide a systematic way to create and manage databases. It allows for the creation of complex data structures, the definition of relationships between different data elements, and the implementation of rules to maintain data consistency and accuracy. This is crucial for applications that rely on accurate and readily available information.

DBMS also plays a vital role in data security by controlling access to the database and protecting it from unauthorized modifications or deletions. It offers mechanisms for backup and recovery, ensuring that data can be restored in case of system failures or other data loss events. Different types of DBMS exist, such as relational, hierarchical, network, and object-oriented, each with its own way of structuring and accessing data. The choice of DBMS depends on the specific needs and complexity of the data being managed.
