andmebaasisüsteemiga, often referred to as a database management system (DBMS), is a software system used to store, manage, and retrieve data. It acts as an interface between users or applications and the actual database files, ensuring data integrity, security, and efficient access.

DBMSs allow for structured organization of data, typically in tables comprising rows and columns. They provide languages, such as SQL (Structured Query Language), to define, manipulate, and query the data. Key functionalities include data definition, data manipulation, data control, and transaction management. Data definition involves creating and modifying the database schema, while data manipulation encompasses inserting, updating, and deleting records. Data control ensures that only authorized users can access and modify specific data. Transaction management guarantees that a series of operations are performed atomically, meaning either all succeed or none do, thus maintaining consistency.

Common examples of DBMSs include relational database management systems (RDBMS) like MySQL, PostgreSQL, Oracle, and SQL Server, which organize data into tables with predefined relationships. Other types include NoSQL databases, which offer more flexible data models for handling large volumes of unstructured or semi-structured data. The choice of a DBMS depends on factors such as the type of data, the required scalability, performance needs, and budget.
