Mark Logic basically makes an XML DBMS – confusingly called Marklogic without a space – optimized for document processing (including text search). Mark Logic’s main market is custom publishing – assembling documents on the fly, whether based on search or some other starting point.
Airlines put Marklogic to an interesting use: They create “electronic flight bags.” Apparently, flight crews typically carry a whole satchel of documents (flight bags) onto a plane, the precise contents of which frequently vary. Marklogic lets these be automatically generated in electronic form.
Well, in recent news it turns out that a $1.4 billion B-1 bomber crashed because a known prudent take-off/maintenance procedure hadn’t been followed. (Something about heating the components to evaporate water that otherwise destroyed the electronics.) This plane-saving had been discovered, but not propagated to all bases and maintenance crews responsible for the B-1. You think something like Marklogic might have helped?

However, a technique learned by some two years ago that had gone widely unknown and unadopted probably would have prevented the crash, Carpenter said. The technique essentially heats the sensors and evaporates any moisture before data calibrations.
“This technique was never formalized in a technical order change or captured in ‘lessons learned’ reports. Hence, only some pilots and some maintenance technicians knew of the suggestion,” according to Carpenter’s executive summary of the accident.
The report said, “The human factor of communicating critical information was a contributing factor to this mishap.”
