How are linear pages accessed in a database?

Accessing linear pages in a database typically occurs one after another, in order. This method follows a sequential approach, which makes it efficient for tasks such as reading large datasets where the rows are structured linearly. When a database is designed with linear storage pages, it can leverage contiguous memory access, allowing for faster retrieval of data because the read head or process does not need to skip around to different locations in memory. This approach significantly enhances performance especially for operations that require scanning entire tables or performing bulk reads.

Sequential access optimally utilizes the cache by loading data in a predictable manner, reducing seek times and making data retrieval more efficient. Furthermore, when data is logged or recorded in a linear format, its retrieval aligns with the physical organization of the data on the storage medium, providing a streamlined process as opposed to random or prioritized access methods that may introduce additional overhead or complexity.
