Describe the concept of data fragmentation in the context of Distributed DBMS. Provide examples of horizontal and vertical data fragmentation.

Data fragmentation is a crucial concept in the realm of Distributed Database Management Systems (DDBMS), where data is distributed across multiple sites or nodes. In this context, fragmentation refers to the division of a database into smaller, more manageable pieces or fragments, which are distributed across different locations within a distributed system. This fragmentation process helps improve data distribution, accessibility, and performance in a distributed environment. There are two primary types of data fragmentation: horizontal and vertical. In this explanation, we will delve into each type, providing examples and insights into their use.
