SQL-based relational databases were a clear choice for the warehouse data store because of their flexible query processing. A series of new companies was formed to build the data extraction, transformation, and database query tools needed by the data warehouse model. In addition, DBMS vendors started to focus on the kinds of database queries that customers tended to run in the data warehouse. These queries tended to be large and complex such as analyzing tens or hundreds of millions of individual cash-register receipts to look for product purchase patterns. They often involved time-series data for example, analyzing product sales or market share data over time. They also tended to involve statistical summaries of data total sales, average order volume, percent growth, and so on rather than the individual data items themselves. To address the specialized needs of data warehousing applications (often called OnLine Analytical Processing or OLAP), specialized databases began to appear. These databases were optimized for OLAP workloads in several different ways. Their performance was tuned for complex, read-only query access. They supported advanced statistical and other data functions, such as built-in time-series processing. They supported precalculation of database statistical data, so that retrieving averages and totals could be dramatically faster. Some of these specialized databases did not use SQL, but many did (leading to the companion term ROLAP, for Relational OnLine Analytic Processing). As with so many segments of the database market, SQL s advantages as a standard proved to be a powerful force. Data warehousing has become a one-billion-dollar-plus segment of the database market, and SQL-based databases are firmly entrenched as the mainstream technology for building data warehouses.

During the late 1990s, the World Wide Web and the web browsing capability that it enabled were the driving force behind the growth of the Internet. With its focus on delivering content in the form of text and graphics, the early uses of the Web had little to do with data management. By the mid-1990s, however, much of the content delivered from corporate web sites had its origins in SQL-based corporate databases. For example, on a commercial web site for a retailer, web pages that contain information about products available for sale, their prices, product availability, special promotions, and the like are typically created on demand, based on data retrieved from a SQL database. The vast majority of the pages displayed by an online auction site or by an online travel site are similarly based on data retrieved from SQL databases, transformed into the Web s HTML page format. In the other direction, data entered by a user into browser page forms is almost always captured into SQL databases that form part of the web site architecture. By the early 2000s, industry attention had turned to the next phase of the Internet, and the role that Internet technologies can play in connecting computer applications to one another. These distributed applications architectures received widespread trade press coverage under the banner of web services. In the long-standing tradition of the computer industry, competing camps emerged, championing different sets of

standards and languages for implementing them a Microsoft-led camp under the .NET framework, and a rival camp focused on Java and J2EE-based application servers. Both architectures embrace a key role for XML, a standard for exchanging structured data like the data that resides in SQL databases. In response to the industry attention on web services, a flurry of products has been announced that link XML-formatted messages to SQL-based databases. Startup database vendors and some of the object database vendors have announced XML-based database products, arguing that they provide an ideal, native match for the XML-formatted exchange of data over the Internet. The established relational database players have responded with their own XML initiatives, adding XML input/output capabilities, and in some cases, XML data type support, to their products. The interaction between XML and SQL is one of the most active areas in data management today, and the activity in this area will keep SQL in the industry spotlight well into the first decade of the twentyfirst century.
