...Data Warehousing Methodologies Using a common set of attributes to determine which methodology to use in a particular data warehousing project. DATA INTEGRATION TECHNOLOGIES have experienced explosive growth in the last few years, and data warehousing has played a major role in the integration process. A data warehouse is a subjectoriented, integrated, time-variant, and nonvolatile collection of data that supports managerial decision making [4]. Data warehousing has been cited as the highest-priority post-millennium project of more than half of IT executives. A large number of data warehousing methodologies and tools are available to support the growing market. However, with so many methodologies to choose from, a major concern for many firms is which one to employ in a given data warehousing project. In this article, we review and compare several prominent data warehousing methodologies based on a common set of attributes. Online transaction processing (OLTP) systems are useful for addressing the operational data needs of a firm. However, they are not well suited for supporting decision-support queries or business questions that managers typically need to address. Such questions involve analytics including aggregation, drilldown, and slicing/dicing of data, which are best supported by online analytical processing (OLAP) systems. Data warehouses support OLAP applications by storing and maintaining data in multidimensional format. Data in an OLAP warehouse is extracted and loaded...

...Data Design Methods Introduction Many organizations and companies rely on databases to run their operations and achieve competitive advantage. Database design refers to the different parts of the design of an overall database system. It can be thought of as the logical data structures used to store data, and the forms and queries used as part of the overall database application within the database management system (Wikipedia.org). The paper focuses on database design methods and steps that can be taken to achieve a good design structure that avoids redundancy, duplicate data or the absence of required data. The need to understand database models Databases are important to the organizational setting. Databases allow organizations to share data across multiple applications and systems. Organizations build several databases each one sharing data with several information systems. This is because it is almost impractical to build one database to meet an entire organization’s needs. Therefore data design is critical to the consistency, integrity and accuracy of the data in a database. A database that is improperly designed will make it difficult to retrieve certain types of information. Besides, there is the risk that searches will produce inaccurate results or information that may have potential damaging effects on a company's bottom line. Inaccurate database may also affect the daily operations of a business and its future direction. A good database addresses the informational...

...be effective. As a member of an IT team, your overarching goal is to ensure that the IT systems ultimately do what the business needs them to do. In this course, you have learned about the key principles and practices underlying the analysis, design, implementation, and management of IT systems. In this final project, you will apply this knowledge by creating a systems proposal document. The project is divided into four milestones, which will be submitted at various points throughout the course to scaffold learning and ensure quality final submissions. These milestones will be submitted in Module Two, Module Four, Module Six, and Module Eight. The final submission will occur in Module Nine. In this assignment, you will demonstrate your mastery of the following course outcomes: Assess the relationship of systems analysis, design, implementation, and development processes as they relate to the management of information technology systems Communicate the paradigms, processes, and activities of systems development to diverse audiences Apply structure and object oriented analysis modeling techniques to analyze, design, and manage information technology systems Construct written and visual representations of the analysis, design, implementation, and management of information technology systems based on the systems development life cycle Prompt You will select your own case study and will apply the content provided, describing the business process to complete...

...give project may have elements of both approaches. The predictive approach to the SDLC is used for projects that are well understood and low risk. The adaptive approach to the SDLC is used for projects that are not well understood and are higher risk. Adaptive SDLCs are more iterative and allow the project team to adapt the project to changing circumstances. The other important concept that you should learn from this chapter are the difference between the two main methodologies to system development that are currently used to develop business systems: the structured approach and the object-oriented approach. The object-oriented approach refers to system development using newer object technologies that require a different approach to analysis, design, and programming. Finally the chapter concludes with a discussion of the Agile philosophy and Agile...

...Transition from 2D Drafting to 3D Modeling Benchmark Report Improving Engineering Efficiency September 2006 — Underwritten, in Part, by — The Transition from 2D Drafting to 3D Modeling Benchmark Report Executive Summary D o more with less. The mandate hasn’t changed for manufacturers. They must develop more products with increasing complexity to address customer and competitive pressures. Yet, there’s no “give” in project timelines to adopt new technologies like 3D modeling to help them win. However, some manufacturers are not only adopting 3D modeling technology, but excelling at hitting their product development targets at the same time. How is it possible? Interestingly enough, it’s actually quite simple. Key Business Value Findings • Best in class manufacturers their hit revenue, cost, launch date, and quality targets for 84% or more of their products. • Best in class performers typically produce 1.4 fewer prototypes than average performers. • Best in class performers average 6.1 fewer change orders than laggard performers. • In total, best in class manufacturers of the most complex products get to market 99 days earlier with $50, 637 lower product development costs. Implications & Analysis How do they do it? • Best in class performers are 40% more likely to have engineers use CAD directly to ensure they stay close to the design. • Best in class performers are 24% more likely to take advantage of extended 3D modeling design capabilities. They are 55% more likely...

...COMPARING PERCEPTIONS OF THE SYSTEMS ANALYSIS AND DESIGN COURSE BRANDI N. GUIDRY University of Louisiana at Lafayette Lafayette, LA 70504 DAVID P. STEVENS University of Louisiana at Lafayette Lafayette, LA 70504 ABSTRACT Information Systems (IS) practitioners and educators have equal interest in the content of the Systems Analysis and Design Course (“SAD”). Previous research has examined instructors’ perceptions regarding the skills and topics that are most important in the teaching of the SAD course and the class time devoted to each. A similar assessment evaluated SAD course content from a practitioner perspective. Both studies used entropy calculations. A comparison of these studies is presented in this paper. For traditional topics, the group (either faculty or practitioner) with greater agreement believes the topic to be deserving of less class time. For structured and object-oriented topics, the group with the greater agreement also believes the topic to be of greater importance. This analysis demonstrates that practitioners and academics agree on approximately 40% of the SAD skills and knowledge areas. Keywords: Systems analysis and design, Structured analysis, Object-oriented analysis, Management Information Systems curricula, Entropy INTRODUCTION It is important that an education in Management Information Systems (MIS) is reflective of practices and techniques that are currently used in industry. Given the pace of technological innovation, there are ever-changing...
