򐂰 TEDW uses open, proven interfaces for extracting, storing, and sharing the
data.
TEDW can extract data from any application (Tivoli and non-Tivoli) and store
it in a common, central database. TEDW also provides transparent access for
third-party Business Intelligence (BI) solutions using the CWM standard, such
as IBM DB2 OLAP, Crystal Decisions, Cognos, BusinessObjects, Brio
Technology, and Microsoft OLAP Server. CWM stands for Common
Warehouse Metadata, an industry standard specification for metadata
interchange defined by the Object Management Group (see
http://www.omg.org). TEDW provides a Web-based reporting front end
called the Reporting Interface, but the open architecture provided by the
TEDW allows other BI front ends to be used to access the data in the central
warehouse. The value here is flexibility. Customers can use the reporting
application of their choice; they are not limited to any specific one.
򐂰 TEDW provides a robust security mechanism.
TEDW provides a robust security mechanism by allowing data marts to be
built with data from subsets of managed resources; by providing database
level authorization to access those data marts, TEDW can address most of
the security requirements related to limiting access to specific data to those
customers/business units with a need to know.
򐂰 TEDW provides a scalable architecture.
Since TEDW depends on the proven and industry standard RDBMS
technology, it provides a scalable architecture for storing and retrieving the
data.
Tivoli Enterprise Data Warehouse concepts and components
This section discusses the key concepts and the various components of TEDW
in the logical order that the measurement data flows: from the monitors collecting
raw data to the final detailed report. Figure 10-1 on page 378 depicts a typical
Tivoli Enterprise Data Warehouse configuration that will be used throughout this
