Andmebaasiühenduste

Andmebaasiühendus, or database connection, refers to the communication link established between an application or a program and a database management system. This connection is essential for any data manipulation operations, such as retrieving, inserting, updating, or deleting data. When an application needs to interact with a database, it first establishes a connection. This process typically involves specifying the database server's address, the database name, and authentication credentials like a username and password.

Once a connection is successfully established, the application can send queries or commands to the database through this connection. The database system processes these requests and sends back the results. After the interaction is complete, it is good practice to close the database connection to free up resources on both the application and the database server. Managing database connections efficiently is crucial for application performance and scalability. Techniques like connection pooling are often employed to reuse existing connections instead of establishing new ones for every request, thereby reducing overhead and improving response times. In summary, an andmebaasiühendus is the fundamental conduit through which applications and databases interact.
