Rowbased

Rowbased is a data storage and retrieval method used in databases, particularly in relational database management systems (RDBMS). In a row-based storage system, data is stored and retrieved one row at a time. Each row in a table is stored as a contiguous block of data, which includes all the columns for that row. This method is in contrast to column-based storage systems, where data is stored and retrieved one column at a time.

Row-based storage is commonly used in transactional databases where the primary operations involve reading and writing entire rows. This approach is efficient for OLTP (Online Transaction Processing) systems, as it minimizes the amount of data that needs to be read or written for each transaction. It also simplifies the implementation of row-level locking, which is crucial for maintaining data integrity and consistency in concurrent environments.

However, row-based storage can be less efficient for analytical queries that involve aggregating data across many rows and columns. In such cases, column-based storage systems, which store data by columns, can be more advantageous as they allow for more efficient data retrieval and aggregation.

Row-based storage is also used in various database systems, including MySQL, PostgreSQL, and Oracle. These systems offer different configurations and optimizations to balance the trade-offs between row-based and column-based storage, depending on the specific use case and workload requirements.
