Fragmentation is a process in which a larger entity, such as a database, file, or network, is divided into smaller, more manageable pieces or fragments. This process can occur for various reasons, including optimization, distribution, or recovery purposes. Fragmentation can be beneficial in certain contexts, such as improving performance, enhancing data availability, or facilitating parallel processing. However, it can also introduce challenges, such as increased complexity in data management and potential data loss if not handled properly.

In the context of databases, fragmentation can refer to the division of a table into smaller, more manageable pieces. This can be done through techniques such as horizontal partitioning, where rows are divided based on certain criteria, or vertical partitioning, where columns are separated. Fragmentation can also occur in file systems, where a file is split into smaller chunks for storage or transmission. In networking, fragmentation can refer to the division of a data packet into smaller fragments to fit through a network with smaller maximum transmission units.

Fragmentation can be a deliberate process, where an entity is intentionally divided into smaller parts, or it can be an unintended consequence of other operations, such as updates or deletions. In either case, it is important to manage fragmentation effectively to maintain the integrity and performance of the system. This may involve techniques such as defragmentation, where fragments are recombined into a single entity, or periodic maintenance to prevent excessive fragmentation from occurring.
