Анотация
     Този официален Oracle курс предлага на студентите изчерпателно въведение в технологиите на базите данни и е първият курс, с който Oracle препоръчва да започнат желаещите да придобият сертификация Oracle Database Administrator или Oracle Application Developer. Покриват се основните концепции в релационните и обектно-релационните бази. Изучава се SQL и неговото използване за създаване, извличане и манипулаиране на данни. Изучават се ROLLUP и CUBE техники, операции с множества и йерархии.
