The DNA category covers all the technologies involved in building applications in a Windows environment. There is a strong web emphasis here, but Wrox books in this category also cover non-Microsoft technologies that come under the DNA umbrella - such as XML - and database technologies like SQL Server and Access. This tree shows the database section of the DNA technology world.One of the great enhancements of the new edition of Microsoft's data warehousing and enterprise management package, SQL Server 2000, is its increased support for XML. XML has taken the industry by storm - not only revolutionizing the way that web pages are generated, but also the way that data is exchanged between disparate systems. The new version of SQL is a significant leap from the highly successful SQL 7. It is tightly integrated with Windows 2000, offering in addition to XML enhancement much improved OLAP (Online Analytical Processing) Services.
