Context and question: IBM started working on a prototype system loosely based on Codd's concepts as System R in the early 1970s. The first version was ready in 1974/5, and work then started on multi-table systems in which the data could be split so that all of the data for a record (some of which is optional) did not have to be stored in a single large "chunk". Subsequent multi-user versions were tested by customers in 1978 and 1979, by which time a standardized query language – SQL[citation needed] – had been added. Codd's ideas were establishing themselves as both workable and superior to CODASYL, pushing IBM to develop a true production version of System R, known as SQL/DS, and, later, Database 2 (DB2).
What did System R work on to change the way data was stored?
Answer: multi-table systems
Context and question: Another residence was maintained at Lake Bled, while the grounds at Karađorđevo were the site of "diplomatic hunts". By 1974 the Yugoslav President had at his disposal 32 official residences, larger and small, the yacht Galeb ("seagull"), a Boeing 727 as the presidential airplane, and the Blue Train. After Tito's death the presidential Boeing 727 was sold to Aviogenex, the Galeb remained docked in Montenegro, while the Blue Train was stored in a Serbian train shed for over two decades. While Tito was the person who held the office of president for by far the longest period, the associated property was not private and much of it continues to be in use by Yugoslav successor states, as public property, or maintained at the disposal of high-ranking officials.
Where was the Galeb docked after Tito's death?
Answer: Montenegro
