1.Database Driver Definition: A database driver is a software component that facilitates communication between an application and a specific DBMS. It acts as an intermediary, allowing the application to send commands, perform queries, and retrieve data from the database in a standardized way.
2.Translation Process: When an application sends a request (such as an SQL query) to the database, the database driver intercepts it. It then translates the request into a format compatible with the DBMS. This ensures that the database can process the query correctly.
3.Supported Protocols: Different database drivers use specific connectivity protocols, such as JDBC, ODBC, or ADO.NET. These protocols define how the driver communicates with the database.
4.Features of Database Drivers:
oEstablishing a Connection: The driver establishes a connection to the database, allowing the application to interact with it.
oExecuting Queries: It handles the execution of queries (e.g., SELECT, INSERT, UPDATE) on behalf of the application.
oFetching Results: The driver retrieves query results and provides them to the application.
oManaging Transactions: It supports transaction management (commit, rollback) to ensure data consistency.
oParameter Binding: The driver handles parameter binding for prepared statements.
oError Handling: It manages errors and exceptions related to database interactions.
5.Additional Functionality: Some drivers offer advanced features like connection pooling, data caching, and query optimization to enhance performance and scalability.
6.Examples of Database Drivers:
oJDBC (Java Database Connectivity): Used for Java applications.
oODBC (Open Database Connectivity): A widely used standard for Windows-based applications.
oADO.NET: Used in Microsoft .NET applications.
