Concept
Connection pooling is a technique used to manage and reuse database connections, thereby reducing the overhead of establishing a connection for each request. It optimizes resource utilization and improves application performance by maintaining a pool of active connections that can be reused when needed.
Concept
Concurrency control is a database management technique that ensures transactions are executed in a safe and consistent manner, even when multiple transactions occur simultaneously. It prevents conflicts and maintains data integrity by managing the interaction between concurrent transactions, ensuring that the system remains reliable and efficient.
Concept
Transaction management is a critical component in database systems that ensures transactions are processed reliably and ensures data integrity despite system failures. It encompasses a set of techniques to control concurrent access, maintain consistency, and ensure atomicity, isolation, and durability of transactions.
Concept
Network protocols are standardized rules that govern how data is transmitted and received across networks, ensuring reliable and secure communication between different devices and systems. They are essential for interoperability, enabling diverse devices and applications to communicate seamlessly within and across networks.
Concept
SQL injection is a type of cyber attack where an attacker exploits vulnerabilities in an application's software by inserting malicious SQL code into input fields to manipulate the database. This can result in unauthorized access to sensitive data, data corruption, or even complete control over the database server.
Concept
Authentication and authorization are critical processes in cybersecurity, where authentication verifies the identity of a user or system, and authorization determines the access level or permissions granted to that authenticated identity. Together, they ensure that only legitimate users can access resources and perform actions within a system, maintaining the integrity and confidentiality of data.
Concept
A Data Source Name (DSN) is a configuration that stores information required to connect to a database, including the database driver, location, and credentials. It simplifies database connectivity by abstracting these details, allowing applications to connect to databases without hardcoding connection parameters.
Concept
Software initialization is the process where a program sets up necessary resources and configurations to prepare for execution and ensure efficient operation. This involves allocating memory, setting initial values for variables, and establishing connections to required services or databases.
