A causal-chain model of accidents is effective in investigating accidents which causes are solely due to failures of the system.
flash memory has become a major database storage in building portable information devices because of its nonvolatile, shock-resistant, power-economic nature, and fast access time for read operations.
As Dekker has posed, investigators should focus on the circumstances of the time and disregard knowledge of the outcome.
"wear and tear" (L.6) is the same as loss or damage resulting from ordinary use and exposure.
due to advances in portable computing and Internet service technologies, applying traditional database technologies to flash memory databases on portable devices poses no difficulties.
Accidents in software development projects and products are nothing new and neither are they likely to cease.
A top-down systems oriented approach shows how different parties may contribute to safety, considering their organizational affiliations.
despite being hundreds of times faster than a hard disk in read operations, flash memory is now one of the best choices for portable information systems.
as a result of the life of its memory blocks, flash memory is the most popular storage media for information management in portable computing systems.
The current models employed to investigate software accidents do not appear to be suited to the task.
