Oracle Cost Based Optimizer Correlations, Robert Apple
Regis University Student Publications (comprehensive collection)
Database systems use optimizers on queries to select execution pathways that are supposed to provide optimal performance. The Oracle database version of this technology is called the Cost Based Optimizer (CBO). Researchers have studied whether Oracle optimizer estimates could be correlated to execution speeds with a high degree of confidence, but have found that correlating optimizer cost estimates with actual execution speed to be problematic and unreliable. If possible, however, such correlations would be helpful to developers who are tasked with query creation and optimization. Although much has been written on databases, the academic literature on optimizers was sparse. To …

Ssd Flash Drives Used To Improve Performance With Clarity Data Warehouse, Douglas Ervin
Regis University Student Publications (comprehensive collection)
Since the introduction of solid-state devices (SSD), both storage area network (SAN) administrators and database administrators (DBA) have imagined the performance gains promised by replacing hard disk drives (HDD). The initial testing in the laboratory did not promise those gains in the real world. The SSD vendors worked between 2007 and 2010 to improve performance, which in industry standard tests showed steady progress. Despite the gains in the laboratory, there were few examples of real world usage particularly in the field of data warehousing. The process of extracting, transforming and loading (ETL) places extreme loads on the ability of the …

Extended Bridge Software Design Pattern, Andrew J. Haigh
Extended Bridge Software Design Pattern, Andrew J. Haigh
Regis University Student Publications (comprehensive collection)
Software engineers are taught that they should separate form and function. This allows a user interface or front-end to be designed and implemented independently of the engine or back-end. Using an abstracted interface class provides the opportunity to develop different user interfaces for the same back-end, as each new user interface will all be derived from this agreed upon abstracted interface. Using the Bridge pattern allows the user to also decouple the abstraction from its implementation, providing additional flexibility as they developed multiple user interfaces. However, user interfaces are typically designed as a single unit, the renderer, even the Bridge …
