...According to Lee, the most popular definition is a data warehouse is a subject-oriented, integrated, time-variant and non-volatile collection of data in support of management’s decision making process (2014). Basically a data warehouse is a copy of transaction data specifically structured for query and analysis. According to Frand, data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and summarizing it into useful information – information that can be used to increase revenue, cut costs, or both (1997). There are many benefits of data warehousing. Yes, it will cost large amounts of money from businesses to have a data warehouse but, in the long run it is worth it to have in a corporation. One benefit is that data warehouses stores and presents information in a way that allows management to make important decisions (Prathap, 2014). Management and even executives can look at the business as a whole instead of by each department. According to Prathap, another benefit of data warehouses is their ability to handle server tasks connected to querying which is not used in most transaction systems (2014). Creating queries and reports can take time and with data warehousing, the server can handle the tasks in a timely fashion. Again, according to Prathap, one of the most important benefits of data warehouses is that they set the stage for an environment where a small amount of technical knowledge about databases...

...Term Paper Data Warehousing and Data Mining Term Paper Data Warehousing and Data Mining A Data Warehouse Saves Time, Enhances Data Quality and Consistency, Provides Historical Intelligence, Generates a High return on investment. One of the benefits to using a data warehouse is that it conveys Business Intelligence By providing data from various sources. Management executives no longer need to make decisions based on finite data. Time is saved by allowing business users to get data quickly from one location so they can make quick knowledgeable decisions and will not waste time trying to get data from several places. Using a data warehouse implementation provides for better data quality and consistency by converting data from different sources into an individual common format. Since data from each department is standardized, each department will have results that are in alignment with the results of all other departments. Doing so assures the accuracy of data and that provides for better business decisions. Since a data warehouse holds large volumes of historical data, it can analyze trends over a time frame so that predictions can be made. This type of data usually cannot be kept or used to get reports in a transactional database. Finally the return on investment for companies instituting a data warehouse and a Business Intelligence system generate more money while also saving money. The purpose of data mining is to provide knowledge to give company an advantage...

...Data Mining/Data Warehousing Matthew P Bartman Strayer University Ibrahim Elhag CIS 111– Intro to Relational Database Management June 9, 2013 Data Mining/Data Warehousing When it comes to technology especially in terms of storing data there are two ways that it can be done and that is through data mining and data warehousing. With each type of storage there are trends and benefits. In terms of data warehousing there are 5 key benefits one of them being that it enhance business intelligence. What this means is that business processes can be applied directly instead of things having to be done with limited information or on gut instinct. Another benefit of data warehousing is that it can also save time meaning that if a decision has to be made the data can be retrieved quickly instead of having to find data from multiple sources. Not only does data warehousing enhance business intelligence and save time but it can also enchance data quality and consistency.This is accomplished by converting all data into one common format and will make it consistent with all departments which ensures accuracy with the data as well. While these key benefits another one is that it can provide historical intelligence which means that analayze different time periods and trends to make future predictions. One other key benefit is that it provides a great return on investment. The reason being that a data warehouse generates more revenue...

...3) Abstract Data is the most valuable enterprise asset, and a properly integrated data management strategy will enhance an organization’s ability to develop valuable insights that will provide greater business value. More specifically, data management is the development and execution of a company’s procedures, policies and architectures: in order to better manage its informational needs in an effective and efficient manner. Data warehousing, online transactional databases, and data mining can solve or reduce difficulties associated with managing data. Solving Data Management Difficulties The concept of data warehousing is to create a central location and permanent storage space for the various data sources needed to support a company’s analysis and reporting. In other words, it is a database that focuses on query and analysis rather than actual transaction processing (Reeves, 2009). It usually contains historical data derived from a company’s transaction data, but may include data from several other sources. Data warehouses separate analysis workload from transaction workload and enable an organization to consolidate data from several sources. Since executives and managers can quickly and efficiently access data from a multiple sources, they are able to make informed decisions on key initiatives promptly: rather than waste time retrieving data from multiple sources. Another benefit of data warehousing is that it stores large amounts of historical data so it can be analyzed...

...head: SHORT TITLE OF PAPER (<= 50 CHARACTERS) Data Warehousing and Data Mining Bruce Nimo CIS 111 March 19, 2012. Prof Jones Data mining is a process of numerical analysis. Analysts use technical tools to query and sort through terabytes of data looking for patterns. Usually, the analyst will develop a hypothesis, such as customers who buy product X usually buy product Y within six months. Running a query on the relevant data to prove or disprove this theory is data mining. Data warehousing describes the process of designing how the data is stored in order to improve reporting and analysis. Data warehouse experts consider that the various stores of data are connected and related to each other conceptually as well as physically. A business's data is usually stored across a number of databases. However, to be able to analyze the broadest range of data, each of these databases needs to be connected in some way. This means that the data within them need a way of being related to other relevant data and that the physical databases themselves have a connection so their data can be looked at together for reporting purposes. Businesses then use this information to make better business decisions based on how they understand their customers' and suppliers' behaviors. Examples of businesses that use data warehousing and data mining are amason.com, Wal-Mart stores Inc etc. Both data mining and data warehousing are business intelligence tools that are used to turn information...

...Business Intelligence and Data Warehouses Kevin Gainey Mr. Brown CIS 111 Data warehouses support business decisions by collecting, consolidating, and organizing data for reporting and analysis with tools such as online analytical processing (OLAP) and data mining. Although data warehouses are built on relational database technology, the design of a data warehouse database differs substantially from the design of an online transaction processing system (OLTP) database. The topics in this paper address approaches and choices to be considered when designing and implementing a data warehouse. The paper begins by contrasting data warehouse databases with OLTP databases and introducing OLAP and data mining, and then adds information about design issues to be considered when developing a data warehouse with Microsoft® SQL Server™ 2000. A data warehouse supports an OLTP system by providing a place for the OLTP database to offload data as it accumulates, and by providing services that would complicate and degrade OLTP operations if they were performed in the OLTP database. Without a data warehouse to hold historical information, data is archived to static media such as magnetic tape, or allowed to accumulate in the OLTP database. If data is simply archived for preservation, it is not available or organized for use by analysts and decision makers. If data is allowed to accumulate in the OLTP so it can be used for analysis, the OLTP database continues to grow in size and...

...important features of data mining tools Data mining is the process of fetching hidden information from huge databases for the purpose of analysis. Basically, it is a method to search for information that can prove to be useful for an organisation and to extract that knowledge from very lengthy and large databases. It uses a variety of statistical algorithms and analysis techniques to derive results. Although, this might sound easy but data mining is a lengthy process and requires loads of time and patience. It requires a lot of man-hours as an application can mine the data from the databases but it is the responsibility of the human to describe the data to look for to the application and also to find and collect the databases. (Naxton, n.d.) Analysis is key to outperforming your competition in today’s world. Almost all businesses rely on data to figure out the future market trends, know more about their customers and their preferences etc. An example of data mining is why companies advertise on Facebook as they get to reach a vast audience and learn about their habits. The information is derived from the advertisements the people click on, the time spent on that specific advert, the type of adverts they hide or like, and all this data is of value to companies to understand the market. Data mining comprises of 5 elements (“Data Mining—Why is it Important?,” n.d.): • “Extract, transform, and load transaction data onto the data warehouse system” • Store data in a MDB system to...

...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 data...
