Question: Give examples of how OLAP works and its Predictive Analytics

On-line analytical Processing (OLAP) refers to a computer-based processing with a capability of manipulating and analyzing large volumes of data from multiple perspectives (different points of view). It is one technique you can use to transform data into information. The original system of the OLAP is also known as the multi-dimensional cube or hyper cube.
For example, a user can request that data be analyzed to display a spread-sheet showing all of a company's products sold in Ghana in the month of January, compare revenue figures with those for the same products in March, and then see a comparison of other product sales in Ghana in the same time period.
Historical Background
The first fully functional on-line analytical system was introduced in 1970 by Express, and later in 1995, the Oracle acquired the release for the resource of information. The formal launching for acquisition of OLAP was held in 2007. Oracle also released its own system called Essbase using the OLAP theoretical background and functionality. In 1998, Microsoft stepped in for upgrading and advancement in the OLAP technology. Microsoft worked on the mainstream idea and developed highly advanced online analytical system that is deployed in many large organizations today.
Types of OLAP
There are 3 types of the on-line analytical systems each with different properties according to the level of use.

Multi-dimensional OLAP
Multi-dimensional OLAP is also known as MOLAP in short. It is a classic type of leading on-line analytical systems. Instead of storing the data in relational form, it has the ability to store data in the multi-dimensional array that is highly optimized. This makes the data storage more efficient and quick.
Relational OLAP
Relational OLAP (ROLAP) works similar to the relational…...

Project Management for Information Systems

...Project Management for Information Systems Project Management for Information Systems Abstract Information systems (IS) projects are vulnerable to resource cutbacks and the increasing complexity of systems and advances in information technology make finding the right personnel difficult and the associated development costs high. Good project management is essential for success. Some alignment methodologies include IBM's business systems planning (BSP), Robert Holland's strategic systems planning, James Martin's (1989) information engineering and method/1 from Anderson Consulting. Critical success factors (Rockart, 1979) methodology focuses on identifying key information needs of senior executives and building information systems around those key needs.

All businesses share one common asset, regardless of the type of business. It does not matter if they manufacture goods or provide services. It is a vital part of any business entity, whether a sole proprietorship or a multinational corporation. That common asset is information. Information enables us to determine the need to create new products and services. Information tells us to move into new markets or to withdraw from other markets. Without information, the goods do not get made, the orders are not placed, the materials are not procured, the shipments are not delivered, the customers are not billed, and the business cannot survive. But information has far lesser impact when presented as raw data. In order to maximize the value of information, it must be captured, analyzed, quantified, compiled, manipulated, made accessible, and shared. In order to accomplish those tasks, an information system (IS) must be designed, developed, administered, and maintained. An information system is a computer system that provides management and other personnel within an organization with up-to-date information regarding the organization's......

The growing supply chains require that software solutions be used in the following sectors: * Web-based ordering * Customer relationship management * Product configuration With the growth of a business, businesses have become much more complex. So in order to reduce such complexity information system helps businessmen as well as managers to simplify the tasks and achieve......

...ASSIGNMENT 2: MANAGEMENT INFORMATION SYSTEMS Read the following case study and then answer Questions 1 - 5 which follow: DELL COMPUTER Michael Dell founded Dell in 1984 while he was still a college student at the University of Texas in Austin. From the beginning, Dell sold directly to_th_e final customer and built PCs to users' specifications. This basic business model has not changed over the years, although it has been modified and refined as the company has grown. Dell started with telephone sales of upgraded IBM compatible PCs, and then shifted to assembling and marketing its own brand of PCs in 1985. It provided customers with a 24-hour hotline for complaints and guaranteed 24- to 48-hour shipment of replacement parts. As its customer base grew, Dell also implemented a direct toll-free technical support line. In 1990, Dell shifted course when it began selling through retail outlets such as CompUSA, Circuit City, and Price Club. Revenues grew rapidly, but problems arose in managing what had become a billion-dollar company, and Dell experienced its first quarterly loss in 1993 (Dell, 1999). In 1994, Dell concluded that even though it was successful selling through retail channels, it was not making money doing so. Dell decided to withdraw from the retail market and return to its roots as a direct seller, a move that not only helped the company's profitability but also enabled it to put all of its efforts into executing the direct model. Dell also brought in a new chief......

...Management Information Systems: A Research Paper By Greg Butler Student ####### American Military University MC302 D002 Summer 07 October 23, 2007 Management Information Systems: A Research Paper Executive Summary. In April 2004, after a year of planning, preparation, and training, the City of La Quinta “went live” with an enterprise-wide, integrated information system for the first time in its 22-year history. For the roughly one hundred member staff, it was a revolutionary leap. Previously, each functional department had selected, purchased, and implemented its own best solution to facilitate day-to-day operations. The implementation of SunGard’s HTE NaviLine software required infrastructure improvements and behind-the-scenes setup. The result was several databases for common use among departments and several automation improvements to previous transaction processing systems. Functional departments, individually and collectively, are able to spend more time concentrating on serving customers and less time searching City Hall for a needed piece of information. Implementation in two final departments will lead to even better service, particularly for those in the development community. The system is challenging, but powerful by virtue of its use of a multi-platform IBM® System i™ server. It is moderately user-friendly by virtue of NaviLine’s Web browser interface. Several improvements are necessary to make the system truly great, but in its current state the......

...the transformation. This requires both the thinking and analysis to compare current state to desired state and define the gap, and the execution capabilities to make the requisite changes happen. Other definition of organizational strategy is a plan for interacting with the competitive environments to achieve organizational goals (Daft, 1995, p. 49). To achieve the organizational strategy, the organization need to come up with some new technology that might help the organization. Technology is one of the central and most significant elements that related to effective operations management in an organization. Internet technology has a direct impact on companies, customers, suppliers, distributors and potential new entrants into an industry (Porter, 2001). Internet technology adoption and use contribute to the creation of competitive advantages (Del Aguila-Obra et al., 2002). Other than that information technology (IT) also can provide some help for organization. Alberto Carneiro, (2006), state in his journal that IT are related to financial services, manufacturing, transport, central government, consultancy, computer manufacturing, retail or wholesaling and publishing because they are depending on all the capacities of IT.
