Data Warehouses, Data Marts
The purpose of a Data Warehouse  is to organize large amounts of stable data for ease of analysis and retrieval and for its design Dimensional modeling is used to organize the data for efficiency of queries that are intended to analyse and summarise large volumes of data. Designing a data warehouse is very different from designing an online transaction processing database.
 
A data mart  is one segment of the data warehouse. Data marts are often used to provide information to functional segments of the organization.
Online Analytical Data Processing (OLAP)
Data processing method designed to handle the queries required to discover trends and critical factors are called online analytical processing (OLAP) systems. OLAP systems operate on OLAP data in data warehouses or data marts. A data warehouse stores enterprise-level OLAP data.
 
OLAP data is organized into multidimensional cubes. The basic unit of a multidimensional cube is called a measure. The measures are organized along dimensions. Each dimension is divided into units called members. The members of a dimension are typically organized into a hierarchy. Similar members are grouped together as a level of the hierarchy.

Oracle introduced the new Oracle9i Database. Oracle9i is the complete internet infrastructure that helps you deploy applications faster while lowering your cost of computing. Two products, Oracle9i Application Server and Oracle9i Database, deliver the industry's highest performance, reliability and security for thousands of popular applications.
 
Data Warehousing
Oracle9i OLAP provides valuable insight into business operations and markets using features previously found only in specialized OLAP databases. Because Oracle9i OLAP is fully integrated into the relational database, all data and metadata is stored and managed from within Oracle9i providing superior scalability, a robust management environment, and industrial-strength availability and security.
 
One of the most important design goals for the SQL Server 2000 team was to construct a database that provides all the tools needed to create powerful e-commerce applications quickly and easily. XML support vastly simplifies back-end system integration and allows for seamless data transfer, even across firewalls. Enhancements like these show why SQL Server is the fastest growing enterprise database in the industry.
Data Analysis
Data Analyzer, which works with Microsoft SQL Server 2000 Analysis Services, is a valuable component of any organization's business intelligence strategy and a key player in the Microsoft business intelligence environment.
