OWB 11gR2 has added significant enhancements in the areas of data warehousing and business intelligence to improve functionality, better exploit improvements in the underlying database, and keep in step with other changes in Oracles product offerings. The following orphan management policies are available: o o o Assign a default parent Reject orphan rows Perform no maintenance Automated orphan management policies improve ETL developer and administrator productivity by addressing an important cause of cube and dimension load failures, without requiring developers to explicitly build logic to handle these orphan rows.
This brings the performance advantages of such storage to users of OWB data warehouse design. Query performance is greatly improved, without the need to make any modification to your queries.
Apart from more efficient use of screen real estate, the new operator includes support for non-equality lookups and dynamic lookups, where the lookup table may be modified during mapping execution. These changes make the lookup operator more powerful in many situations, including improving Type 2 slowly changing dimension support.
Data lineage of objects in OBI EE reports can be traced back to source tables, down to the individual column level. Chunking for Parallelizing Large Table Updates Chunking in Warehouse Builder automates the use of a "divide and conquer" approach to parallelize the processing of large updates.
Users enable chunking for a mapping and define chunking criteria to partition the updates. Oracle Warehouse Builder 11gR2 New Features: Data Integration and Data Warehousing Chunking avoids the need for large rollback segments required by set-based processing of large updates.
Set-based SQL statements for large updates require large rollback segments, because a single set-based statement does not perform intermediate commits. Large updates can be performed incrementally, and if interrupted, chunks already processed do not have to be processed again. Without chunking, if a large update terminates for some reason, all processing must be repeated. Chunking therefore allows fuller exploitation of hardware resources even in cases where use of set-based code is not an option or not the best option.
OWB-EE 11gR2 Administration Enhancements Significant enhancements for OWB 11gR2 administrators include: o o o Multiple Configuration Management usability enhancements Licensed Feature Restriction Check for Updates Multiple Configuration Management Enhancements For customers using multiple configuration management to handle promotion of code from development to test to production environments and associated configuration changes, there are several enhancements.
The OWB user interface for viewing and managing multiple configurations has been redesigned to simplify and clarify previously complex tasks, including: o o o o o Side-by-side editing of attribute values for multiple configurations for an object Editing the configuration values for an object across all configurations Configuring groups of objects at the same time Using configuration templates to set default configuration values for different object types Copying and pasting of configuration attribute values These improvements add business value by enabling users to take full advantage of the flexibility provided by multiple configurations.
There are also extensions to multiple configuration management to support associating multiple execution unit and code template selections with a single logical mapping. Oracle Warehouse Builder 11gR2 New Features: Data Integration and Data Warehousing Licensed Feature Restriction The first patch release of OWB 11gR2 will add a feature that enables the repository owner to enable or disable separately licensed functionality of Warehouse Builder, such as data profiling, data quality, and advanced data warehousing and data integration.
Features that require licenses not selected will be blocked off to prevent inadvertent use. This will make it simpler for OWB users to remain in compliance with their licenses.
More efficient and flexible use of screen real estate.
