Autor: Date, C. J. AnotaceThe SQL language has established itself as the linqua franca database management; it provides the basis for systems interoperability, application portability, client/server operation, distributed database, and more, and is supported by just about every DBMS on the market today. SQL2 - or, to give it its official name, the International Standard Database language SQL (1992) - represents a major set of extensions to the earlier SQL standard. For a start, the new specification is well over 600 pages, compared with less than 100 for the original version. No database professional can afford to ignore it.
