What are nested transactions in MySQL?
Nested Transactions are transactions within transactions and are currently not supported by MySQL. Nested Transactions are not even vaguely related to Co-related Queries.
What concurrency control techniques are used in MySQL?
MySQL employs several concurrency control techniques, primarily using multi-version concurrency control (MVCC) to manage concurrent transactions. MVCC allows transactions to read data without locking, thus improving performance and reducing contention. InnoDB, the default storage engine, utilizes row-level locking for write operations, ensuring that multiple transactions can occur simultaneously without interfering with each other. Additionally, MySQL supports various isolation levels, such as READ COMMITTED and SERIALIZABLE, to control the visibility of changes made by concurrent transactions.
What is MyISAM in MySQL?

What file organization is used in mysql?
MySQL primarily uses a storage engine called InnoDB, which organizes data in a clustered index. In this structure, data rows are stored in the leaf nodes of the B-tree, with the index itself also being stored in a B-tree format. This allows for efficient data retrieval and supports features like transactions and foreign key constraints. Other storage engines, like MyISAM, use different file organization methods, such as non-clustered indexes, but InnoDB is the default and most widely used in MySQL.
How does MySQL work?
MySQL is a relational database management system (RDBMS) that uses Structured Query Language (SQL) to manage and manipulate data stored in tables. It operates on a client-server model, where the MySQL server handles data storage, retrieval, and management, while clients send queries and receive results. Data is organized in structured tables, and relationships between tables are defined using keys. MySQL ensures data integrity and supports transactions, allowing multiple operations to be executed reliably.
