The document discusses different methods for storing data in a database management system, including sequential storage, indexing, and hashing. It describes the benefits and drawbacks of each method. Sequential storage allows for fast sequential retrieval but slow random access. Indexing improves random access time through the use of pointers but can be slow for inserts. Hashing converts key values directly to storage locations, allowing very fast random access, but has no sequential retrieval and is susceptible to collisions.
