phpMyAdmin: Key Features and Capabilities Explained

phpMyAdmin is a web-based MySQL database management tool that allows users to manage databases through a graphical user interface (GUI). 1. It interacts with the MySQL database through PHP scripts, converts user operations into SQL queries and renders the results. 2. Basic usage includes creating databases and tables, such as creating databases named 'my_database' and 'users' tables. 3. Advanced usage supports complex queries and user permission management, such as finding users with specific user names. 4. Common error debugging techniques include checking SQL syntax, managing permissions, and viewing logs. 5. Performance optimization suggestions include index optimization, query optimization and ensuring security.

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.
