DatabaseConnector

DatabaseConnector is a software component or module designed to facilitate communication between an application and a database. Its primary role is to establish a connection, manage that connection, and enable the execution of database operations such as querying, inserting, updating, and deleting data. This abstraction layer shields the application logic from the intricate details of the underlying database system, promoting portability and simplifying development.

A typical DatabaseConnector handles tasks like authentication, connection pooling, and error handling. By managing a pool of active connections, it can reduce the overhead associated with establishing new connections for each database request, thereby improving performance. It often translates application-specific requests into the appropriate database language, such as SQL, and then interprets the results back into a format the application can understand. Different DatabaseConnectors exist for various database systems like MySQL, PostgreSQL, SQL Server, and Oracle, each tailored to the specific protocols and APIs of its target database. This allows developers to switch database backends with minimal changes to their application code, provided they use a compatible DatabaseConnector.
