Partitioning is the process of dividing a larger dataset or system into smaller, manageable parts called partitions. This technique is commonly used in computer science and data management to improve performance, organization, and efficiency. By breaking down data, it becomes easier to access, analyze, and maintain. In databases, partitioning can enhance query performance by allowing the system to search through smaller subsets of data rather than the entire dataset. This method is often applied in systems like SQL databases and NoSQL databases, where data can be partitioned based on specific criteria, such as date ranges or geographic locations.
