Mistrzowski SQL. 61 technik pisania wydajnego kodu SQL

John L. Viescas, Douglas J. Steele, Ben G. Clothier

Bazy danych umożliwiają bezpieczne przechowywanie i użytkowanie danych. Dobrze napisana baza danych pracuje szybko i wydajnie. Najlepsze relacyjne bazy danych są nierozłącznie związane z językiem SQL, zatem aby profesjonalnie podejść do tego tematu, trzeba ten język dobrze opanować. SQL może wydawać się trudny i złożony, a co więcej, dla poszczególnych baz istnieją specyficzne dialekty SQL, niemniej jednak wspaniałe zalety najlepszych baz danych dostępne są tylko dla tych, którzy opanują sztukę pisania efektywnego kodu SQL. Niniejsza książka jest świetnym kompendium przeznaczonym dla osób o podstawowej znajomości SQL. Dzięki niej poznasz najlepsze współczesne techniki pisania w tym języku. Każdą z nich poparto realistycznymi (i przydatnymi!) przykładami. Innymi słowy, znajdziesz tu zrozumiale objaśnione sztuczki ekspertów i mnóstwo użytecznego kodu. Poza zagadnieniami składni omówiono również tematykę optymalizacji projektu bazy, a także zarządzania hierarchiami i metadanymi. Wyjątkowość tej książki polega na tym, że zawarty w niej materiał bez trudu zastosujesz do baz: IBM DB2, Microsoft Access, Microsoft SQL Server, MySQL, Oracle Database czy PostgreSQL. Spośród 61 zagadnień ujętych w książce warto wspomnieć o: zasadach projektowania modelu danych sposobach na efektywne wykorzystanie indeksów i więzów integralności metodach szybkiego wyszukiwania danych z zastosowaniem algebry relacyjnej stosowaniu podzapytań i złączeń tajnikach tabel kalkulacyjnych zbiorach zagnieżdżonych i domknięciach podległości Przekonaj się, jak szybki i wydajny może być Twój kod SQL!
