because the system is designed to be able to handle complex queries for information much faster than are traditional databases, designing and implementing such an attack becomes more difficult and complex (Warigon, 1997). At the same time, the ease with which information in a data warehouse can be manipulated creates more significant problems than a traditional database should unauthorized access be obtained (TechFaq, 2010). While no database or information system could possibly have all necessary security precautions embedded within the structure of its basic operations -- i.e. storing, classifying/analyzing, and retrieving data -- as it is simply not in the nature of an information system to provide such security, data warehouses are at a special level of risk due to the organization of data and the speed at which it is processed (TechFaq, 2010; Warigon, 1997). Building effective...
This makes data warehouses not only some of the most efficient and effective information tools available to many corporations, but also among some of them more secure when properly maintained (Nishith, 2005; Warigon, 1997).
Data Warehousing and Data Mining Executive Overview Analytics, Business Intelligence (BI) and the exponential increase of insight and decision making accuracy and quality in many enterprises today can be directly attributed to the successful implementation of Enterprise Data Warehouse (EDW) and data mining systems. The examples of how Continental Airlines (Watson, Wixom, Hoffer, 2006) and Toyota (Dyer, Nobeoka, 2000) continue to use advanced EDW and data mining systems and processes to streamline
Data Warehousing Data Warehouse technology has changed the way that global organizations conduct business. Many have found it impossible to create a business strategy without a data warehouse. The purpose of this discussion is to research and explain the importance of data warehouse management. We will begin by defining data warehouse and describing the business uses for the technology. Our discussion will then focus of data warehouse management. We will examine the
In addition, the support of multiple taxonomies is also critical for a data warehouse, and to the extent the architects have created a database architecture that will provide for metadata definition and re-defining of taxonomies is the extent to which the data warehouse will have greater use in the organization. Without a strong focus on these aspects of data agility, a data warehouse can quickly become outmoded and only
Data Warehousing and Mobile Computing Walmart is the largest company in the world with the estimated one million customers every hour and more than 100 million customers every week. A large number of customer and gigantic supply chain make the company start using the RFID system to track moving items and manage the supply chains. However, the RFID produces gigantic datasets, which may be challenging to store in the relational database.
Since poor data quality within a system often results in poor business decisions being made from this data, it is very important that each administrator or system architect look at each customer or end-user differently, in their own unique light. Since each end-user is different, and the needs of the customer often stem from the warehouse's ability to accurately store quality information, a system that dates back to the 1970's
