This paper examines correctness issues that arise in distributed database design. A distributed relational database design is traditionally considered to be valid if every global relation can be reconstructed from its fragments by join operations. In this paper, three successively less restrictive definitions of validity are presented, each providing progressively improved handling of incomplete information. Examining these forms, a hybrid reconstruction approach involving inner- and outer-joins is proposed and we briefly describe its application to query formulation. We also propose replacing the notion of global reconstructability with the less restrictive, yet intuitively natural notion of object reconstructability. Universal relations need not be constructed. The need for maintenance of constraints across sites of a distributed system is discussed, and the notion of a distributed referential constraint is proposed which fulfills this need.

Раздался телефонный звонок. Директор резко обернулся.

 - Если бы в игрушке Стратмора завелся вирус, он бы сразу мне позвонил. Стратмор человек умный, но о вирусах понятия не имеет. У него в голове ничего, кроме ТРАНСТЕКСТА.

Она прилетела за. Ангел заговорил: - Дэвид, я люблю. Внезапно он все понял. Сьюзан на экране тянулась к нему, плача и смеясь, захлестнутая волной эмоций.

Мгновение спустя она удовлетворенно вскрикнула: - Я так и знала. Он это сделал.

Сьюзан завороженно смотрела на захватывающую дух технику. Она смутно помнила, что для создания этого центра из земли пришлось извлечь 250 метрических тонн породы. Командный центр главного банка данных располагался на глубине шестидесяти с лишним метров от земной поверхности, что обеспечивало его неуязвимость даже в случае падения вакуумной или водородной бомбы.

 - За счет заведения. Превозмогая шум в голове, Беккер представил себе грязные улицы Трианы, удушающую жару, безнадежные поиски в долгой нескончаемой ночи. Какого черта. Он кивнул. - Si, echame un poco de vodka.

Сьюзан напряглась как тигрица, защищающая своего детеныша. - Сьюзан, ты же говорила с. Разве Дэвид тебе не объяснил. Она была слишком возбуждена, чтобы ответить.

Стратмор хмыкнул. Мысль Сьюзан показалась ему достойной внимания. - Неплохо, но есть одно .
