Since the specifics of creating the data warehouse are determined by the database system, this paper will devote its discussion to the design or layout of the data warehouse. Before discussion of the layout of the data ware house proceeds, the basics about a data warehouse need to be discussed. Then the elements of the data ware house will be covered. What is a Data Warehouse? A data warehouse is a warehouse full of data, an electronic warehouse. In a manner of speaking this is true.

Mining the Data Warehouse

...Mining the Data Warehouse Summary In “Mining the Data Warehouse”, It speaks of a survey done by Merrill Lynch back in 2006. It tells us that “business intelligence software and data-mining tools were at the top of CIOs’ technology spending list” (Baltzan, Hag, Phillips 87). It gives a few examples of how companies are using the software and tools to gain very valuable information. When Ben & Jerry’s is mentioned, people know the brand and immediately think of ice cream. “Ben & Jerry’s cuts through the din by using integrated query, reporting, and online analytical processing technology from BI software vendor Business Objectives” (Baltzan, Hag, Phillips 87). They use the technology to track each pint’s ingredients throughout its life. If there is a complaint made by a customer, they will track it back through ingredients, suppliers, or whatever caused the issue. They are extremely focused on quality of their products. “The BI tools let Ben & Jerry’s officials access, analyze, and act on customer information collected by the sales, finance, purchasing, and quality-assurance departments” (Baltzan, Hag, Phillis 87). They have gotten it down to a science. They can tell you what milk a customer prefers for the ice cream. In 2005, they tracked over 12,500 customer’s information and comments.

Databases vs Data Warehouses

...DIFFERENCE BETWEEN DATABASE AND DATA WAREHOUSE 1 Database vs Data Warehouse Patricta Eric Doller Prudue University Relation Database Management Systems Bob Estein March 14, 2015 DIFFERENCES BETWEEN DATABASE AND DATA WAREHOUSE Relational database versus a data warehouse Businesses use new technology in many aspect of running everyday duties, like record keeping. To keep these records organized, companies have separate database and data warehouses. A database is used for a single application, mostly for transactions. These transactions can range from payroll, inventory to sales and any other transaction the company needs on a daily bases. A data warehouse is used for multiple domains running simultaneously. A company should use a data warehouse to show how they are doing, in whole, rather than just in certain areas. The warehouse can also track business trends. Companies do not usually do not put all their information into one database because of the possibility of being hacked into easily by a Hacker and used for the wrong intent. Although, it 2 would be cheaper to have just one database the security risks are too high. These problems would lead to dissatisfied customers, lack of business and lawsuits. So how is a data warehouse different from your regular database? After all, both of these are database, and they tend to function the same way. If you look deeper into them, you will find that they both have tables and they contain data. They both have indexes,......

Data Warehouses

...huge amounts of data that is stored in a data warehouse that is used for the company’s employees. The employees will pull data that is needed each day to do their daily tasks. The company handles with several different parts that make up one part. Each part is labeled and has a barcode so that the part can be identified. The system that holds all of the data is basically a data warehouse that when an employee needs certain information about a single part can be retrieved from the data warehouse. The data warehouse is also used to follow the vendors to see how well they are doing. What I mean by see how they are doing is to follow how many good parts they build versus the bad parts that are built and sent to the company. The data that is recorded when a bad part is found leads to an inspection of the parts. When the inspection starts there are required steps that are followed and entered into the database. When this data is entered into the database it can show how many parts that have been inspected and how many were good and how many bad. With this company’s regular database that is being used every day and the data warehouse being used to see how the parts are being handle and how the vendors are doing, there are a lot of variables that are put in place for the company.

Rei/ Data Warehouse

...Data Warehouse A data warehouse has many different processes that require several different technologies. Batch and transaction processing data has to first be taken out of the operational databases and then it can be cleaned up. Then the data is uploaded onto a relational database. Data warehouses are the basis for customer relationship management systems because they can be used for consolidating customer data and identifying areas of customer satisfaction and frustration. These warehouses can be used for fraud detection, production analysis, profit center, and corporate management. For retailers, a data warehouse can help identify customer demographics, identify shopping patterns, and improve mailing responses. Data Warehouse REI The data warehouse REI is building is going to have many different types of information about its customers. In order to better serve its clientele, REI has to know what their customers do outdoors.

Modeling Data Warehouse

...Question: 1. When developing a successful data warehouse, what are the most important risks and issues to consider and potentially avoid? Data warehouse projects have many risks. Most of them are also found in other IT projects, but data warehousing risks are more serious because data warehouses are expensive, time-and-resource demanding, large-scale projects. Each risk should be assessed at the inception of the project. When developing a successful data warehouse, it is important to carefully consider various risks and avoid the following issues: • Starting with the wrong sponsorship chain. You need an executive sponsor who has influence over the necessary resources to support and invest in the data warehouse. You also need an executive project driver, someone who has earned the respect of other executives, has a healthy skepticism about technology, and is decisive but flexible. You also need an IS/IT manager to head up the project. • Setting expectations that you cannot meet. You do not want to frustrate executives at the moment of truth. Every data warehousing project has two phases: Phase 1 is the selling phase, in which you internally market the project by selling the benefits to those who have access to needed resources. Phase 2 is the struggle to meet the expectations described in Phase 1. For a mere $1 to $7 million, hopefully, you can deliver. • Engaging in politically naive behavior. Do not simply state that a data warehouse will help managers make better......

Data Warehouses and Data Mining

...Data Warehouses and Data Mining Your Name DBM 384 May 13, 2013 Jim Cervi Data Warehouses and Data Mining Data warehouses serve an integral function within many different industries. In the government and law enforcement agencies this is especially prevalent. Vast amount of data and information from multiple sources is often collected by these agencies. This data and information must be put into a format that allows for workable details by the analysts (HowStuffWorks.com, 2012). Data mining and data warehouses provide these agencies with the ability to select specific data out of the large volumes of data available to the analyst Data Warehouse A data warehouse is a database of information collected from several resources, saved under a specific schema, at only one site according to (Siberschatz, Korth, & Sudarshan, 2011). This type of system is effective for government intelligence agencies in storing and categorizing the data sources. By effectively categorizing and storing the data, the data warehouse provides the analyst with a location where an effective query can produce tailored and specific results from vast stores of records. The data warehouse does this by linking the data sources through common threads. These threads are what allow the analyst to access the correct related information through the query. The data warehouse provides the structure of the data sources that the information will be categorized in. To be truly effective, a well-designed......

...diagram, the following: Primary Data Warehouse and Data Mart. In this connection, explain the difference between ROLAP and MOLAP. A Primary Data Warehouse is a central repository of a database of a complete organization. It holds multiple subject areas and very detailed information. A Data Mart is a subset or an aggregation of the data stored to a primary data warehouse. It often holds only one subject area – for example, a specific department, finance or sales. It may hold more summaried data, and is typically smaller than a warehouse because of its employment on a different grain. Figure 1.1 illustrates the difference between data mart and a primary data warehouse. Since the data mart typically holds one subject area, it is much smaller than a primary data warehouse. These data marts can be viewed as small, local data warehouses replicating the part of primary data warehouse which is required by a specific domain or department.

Data Warehouse-Rei

...Data Warehouse is an application that collects data information to assist marketing and financial improvements through sales transactions and other dealings. This storage system holds large data files of consumers and other dealings within a company. The data collected from transactions assists companies with making decision that can better serve consumers as well as company reports. This stored information is more reliable because of its day-to- day transactions reports. Utilizing this type of system can be cost effective for storing large information for various companies. Once data is stored, the information is available to anyone, however it cannot be altered (Laudon & Laudon, 2013, p. 160). REI is building a data warehousing system, in order for the organization to have a better method to recognize each consumer’s interactions with the company. Information collected such as purchases and transactions through online, catalogs, stores and websites browsing is stored within the system. This will enhance REI’s customer service by allowing them to track the interest of co-ops, send notifications of recalls for particular items, and make it easier to search or query items up with a specific product number. REI had a vision of being connected with its consumers so they could better serve them. They also wanted to tailor the products to the needs of the consumer, while also being user-friendly.

Assignment 3: Business Intelligence and Data Warehouses

...Intelligence and Data Warehouses Kevin Sloley Professor Dammlash Gebre CIS-111 Intro to Related Database Management Systems Due March, 2016 Outline the main differences between the structure of a relational database optimized for online transactions versus a data warehouse optimized for processing and summarizing large amounts of data. The primary difference between your application database and a data warehouse is that while the former is designed (and optimized) to record, the latter has to be designed (and optimized) to respond to analysis questions that are critical for your business. Application databases are OLTP (On-Line Transaction Processing) systems where every transaction has to be recorded, and super-fast at that. Consider the scenario where a bank ATM has disbursed cash to a customer but was unable to record this event in the bank records. If this started happening frequently, the bank wouldn't stay in business for too long. So the banking system is designed to make sure that every trasaction gets recorded within the time you stand before the ATM machine. This system is write-optimized, and you shouldn't crib if your analysis query (read operation) takes a lot of time on such a system. A Data Warehouse (DW) on the other end, is a database (yes, you are right, it's a database) that is designed for facilitating querying and analysis. Often designed as OLAP (On-Line Analytical Processing) systems, these databases contain read-only data that can be......
