Database interactions refer to the processes through which applications communicate with a database to retrieve, store, or manipulate data. This typically involves using a query language, such as SQL (Structured Query Language), to send requests to the database. The database then processes these requests and returns the relevant information or confirms that changes have been made. These interactions can occur in various ways, including CRUD operations, which stand for Create, Read, Update, and Delete. Each operation allows users to manage data effectively. For example, a user might create a new record, read existing data, update information, or delete outdated entries, ensuring the database remains current and useful.
