Cutting-edge Oracle data warehousing from people creating the software. Oracle8i Data Warehousing explains how to design, develop, and administer powerful data warehouses and data marts on Windows NT using Oracle's major new industry-leading database. This authoritative guide helps database developers, administrators, and designers master the major new data warehousing and Internet capabilities in Oracle8i and specifically plan and implement affordable and successful data warehouses and data marts. In one exciting package, this book brings together three hot computing topics: new Oracle databases, Windows NT, and Internet technologies. Data warehouses and smaller data marts allow companies to pool and analyze large quantities of data, yielding valuable information about customers and business processes. Data warehouses have in the past been expensive and very complex. Oracle8i is an important new version of Oracle Corporation's market-leading database system. Most of the significant new features in Oracle8i are for data warehousing, Internet development, or optimizations for the Windows NT platform. Oracle8i and Windows NT together will make data warehouse projects easier and more affordable. Written by data design and warehousing experts from the Oracle8i development team Explains how to design and build data warehouses and data marts on Windows NT Explains how to establish Web/Intranet access to a data warehouse

More than sixty percent of Oracle8i's new features affect data warehousing - how users store, gather and leverage the information contained in their database systems. Oracle's data warehousing is going mainstream spurred by the increasing need to harvest information to provide strategic direction and growth for e-business. Many corporations consider data warehousing essential -from spreadsheet/financial data to high-level strategic data. Oracle8 Data Warehousing provides data warehousers with the means to collect, analyze and act on information contained on their database system.

"This book should satisfy those who want a different perspective than the official Oracle documentation. It will cover all important aspects of a data warehouse while giving the necessary examples to make the reading a lively experience. - Tim Donar, Author and Systems Architect for Enterprise Data WarehousesTuning a data warehouse database focuses on large transactions, mostly requiring what is known as throughput. Throughput is the passing of large amounts of information through a server, network and Internet environment, backwards and forwards, constantly! The ultimate objective of a data warehouse is the production of meaningful and useful reporting, from historical and archived data. The trick is to make the reports print within an acceptable time frame.A data model contains tables and relationships between tables. Tuning a data model involves Normalization and Denormalization. Different approaches are required depending on the application, such as OLTP or a Data Warehouse. Inappropriate database design can make SQL code impossible to tune. Poor data modeling can have a most profound effect on database performance since all SQL code is constructed from the data model.* Takes users beyond basics to critical issues in running most efficient data warehouse applications* Illustrates how to keep data going in and out in the most productive way possible* Focus is placed on Data Warehouse performance tuning

Write powerful queries using as much of the feature-rich Oracle SQL language as possible, progressing beyond the simple queries of basic SQL as standardized in SQL-92. Both standard SQL and Oracle’s own extensions to the language have progressed far over the decades in terms of how much you can work with your data in a single, albeit sometimes complex, SQL statement. If you already know the basics of SQL, this book provides many examples of how to write even more advanced SQL to huge benefit in your applications, such as:Pivoting rows to columns and columns to rowsRecursion in SQL with MODEL and WITH clausesAnswering Top-N questionsForecasting with linear regressions Row pattern matching to group or distribute rowsUsing MATCH_RECOGNIZE as a row processing engineThe process of starting from simpler statements in SQL, and gradually working those statements stepwise into more complex statements that deliver powerful results, is covered in each example. By trying out the recipes and examples for yourself, you will put together the building blocks into powerful SQL statements that will make your application run circles around your competitors. What You Will LearnTake full advantage of advanced and modern features in Oracle SQL Recognize when modern SQL constructs can help create better applicationsImprove SQL query building skills through stepwise refinementApply set-based thinking to process more data in fewer queriesMake cross-row calculations with analytic functionsSearch for patterns across multiple rows using row pattern matchingBreak complex calculations into smaller steps with subquery factoring Who This Book Is For Oracle Database developers who already know some SQL, but rarely use features of the language beyond the SQL-92 standard. And it is for developers who would like to apply the more modern features of Oracle SQL, but don’t know where to start. The book also is for those who want to write increasingly complex queries in a stepwise and understandable manner. Experienced developers will use the book to develop more efficient queries using the advanced features of the Oracle SQL language.
