ABSTRACT :-

Collection of integrated, subject-oriented, time-variant and non-volatile data in support of managements decision making process.

Described as the "single point of truth", the "corporate memory", the sole historical register of virtually all transactions that occur in the life of an organization.

A fundamental concept of a data warehouse is the distinction between data and information. Data is composed of observable and recordable facts that are often found in operational or transactional systems. At Rutgers, these systems include the registrar’s data on students (widely known as the SRDB), human resource and payroll databases, course scheduling data, and data on financial aid.

In a data warehouse environment, data only comes to have value to end-users when it is organized and presented as information.

Information is an integrated collection of facts and is used as the basis for decision-making. For example, an academic unit needs to have diachronic information about its extent of instructional output of its different faculty members to gauge if it is becoming more or less reliant on part-time faculty.

    This document is a proposal for building a data warehouse architecture that will consolidate and transform data into useful information for the purpose of decision-making and for establishing a new function that offers a broad array of decision support services to all units at ABC Retail Chain Corporation. Executives and decision-makers often need information to analyze the past, describe current circumstances, and anticipate the future. Presently, decision-makers across the Institute rely on hard copy reports or Excel Sheets to provide information. Typically, any request for information is forwarded to the operational areas of the Organization, which provide hard copy reports reflecting the data gathered in their functional area. To analyze and transform data into useful information, decision-makers and their staff have to manually re-enter the non-integrated data into their own mini-systems. This type of operation hinders the ability of decision making and the executives are either drowning in too much data with no option to analyze it or too little data, which means they are back to square one and must request additional information. Often executives receive multiple, conflicting information or information that is based on incomplete assumptions about the types of analysis required.…

    The most important aspect of having data warehousing is the fact that it allows for data storage and presentation of this data enabling executives to make sound decisions. Another important use of data warehousing is it takes the separate areas the company is divided up in and takes it all and lumps it in to one single entity. One great benefit of data warehousing is that Huffman will be able to handle server task connected to all queries which is not commonly found in all systems. “Another powerful benefit of data warehouses is that they allow companies to use data modeling for querying tasks that are quite difficult for transaction processing” (Exforsys, 2007). Huffman trucking is already successful but by implementing a success data warehousing system they would be able to understand and analyze all data coming in and leaving the system better and at a more efficient rate.

    First let’s start off by describing data, data is information that has been translated into a form that is more convenient to move or process. Data can also consist in a variety of different forms, like numbers, text, money and even facts stored in your own mind. For example, say you have a check book and are continually using the log to keep up on purchases. That would be classified as a data log because you are storing information to keep as an easy access for future reference.…

    If I were to design Ben & Jerry's data warehouse I would use several dimensions of information. The first dimension would consist of the company's products; ice cream, frozen yogurt or merchandise. The marketing department has to know which products are selling, if Ben & Jerry's didn't know that their T-shirts are selling out as soon as they hit the stores, then they wouldn't be able to take advantage of the opportunity to sell the shirts. The second dimension would consist of the different areas of sales; US, Canada, Mexico, or Europe. I am not sure if they sell their ice cream in Mexico, but with data collection they can find out if their ice cream would be a better seller in the hot climate, rather than pushing for greater distribution in Canada. The third dimension would consist of the "specifics"; where the sale was made, when the sale was made, and who purchased the product. This information can help in the design of the product to focus on the buyer; it can tailor flavors to seasons, and packaging to buyer who looks for the better-looking product. If Ben & Jerry's could know when a season was coming to an end in a specific area, then they could forecast the need or the decline in need and speed up, or slow down distribution to those areas. The focus of the information is that it needs to be useful, and almost any information is useful.…

    As a data architectural framework, an EDM is the "starting point" for all data system designs. The model can be thought of much like an architectural blueprint is to a building; providing a means of visualization, as well as a framework supporting planning, building and implementation of data systems. For enterprise data initiatives, such as an Operational Data Store (ODS) or Data Warehouse (DW), an EDM is mandatory, since data integration is the fundamental principle underlying any such effort. An EDM facilitates the integration of data, diminishing the data silos, inherent in legacy systems. It also plays a vital role in several other enterprise type initiatives:…

    A “database,” no matter how copious, is not information. It is information’s ore. For raw material to become information, it must be organized for a task, directed toward specific performance, applied to a decision. Raw material cannot do that itself. Nor can information specialists. They can cajole their customers, the data users. They can advise, demonstrate, teach. But they can no more manage data for users than a personnel department can take over the management of the people who work with an executive.…

    In the 1990s, as businesses grew more complex, corporation spread globally, and competition became fiercer, business executives became desperate for information to stay competitive and improve the bottom line. Data warehousing technologies have been successfully deployed in many industries: manufacturing (for order shipment and customer support), retail (for user profiling and inventory management), financial services (for claims analysis, risk analysis, credit card analysis, and fraud detection), transportation (for fleet management), telecommunications (for call analysis and fraud detection), utilities (for power usage analysis), and healthcare (for outcomes analysis). This paper presents a roadmap of data warehousing technologies, focusing on the special requirements that data warehouses place on database management systems (DBMSs).…
