Database Partitioning is a technique used to divide a large database into smaller, more manageable pieces called partitions. Each partition can be stored and accessed separately, which helps improve performance and makes it easier to manage data. This approach allows for faster queries and can enhance the overall efficiency of data retrieval. There are different methods of partitioning, such as horizontal partitioning, where rows are divided based on certain criteria, and vertical partitioning, where columns are split. By organizing data in this way, databases can handle larger volumes of information while maintaining speed and reliability.
