Gestión del conocimiento es el proceso por el cual una organización, facilita la trasmisión de informaciones y habilidades a sus empleados, de una manera sistemática y eficiente. Es importante aclarar que las informaciones y habilidades no tienen por qué estar exclusivamente dentro de la empresa, sino que pueden estar o generarse generalmente fuera de ella. Este matiz final es muy importante. Generalmente la mayoría de las empresas identifican gestión del conocimiento solamente con la información y habilidades internas de la empresa, lo que se conoce como Business Intelligence o inteligencia empresarial. De esta forma casi todos los esfuerzos se orientan a canalizar la información y habilidades que ya posee una organización centrándose en la eficiencia de los procesos de comunicación interna a través de la implantación de sistemas como CRM, ERP y un CMI Esto ha sido tradicionalmente así por que siempre ha sido mucho más fácil controlar los volúmenes de información interna que la información externa que se encuentra fuera de la organización que es más difícil de encontrar, buscar, seleccionar y organizar...

...database structures, specialized servers, and Web-enable software products (O'Brien & Marakas, 2011). The ability to analyze and synthesize the available data can be a source of a competitive advantage for any firm. Online Analytical Processing (OLAP) is one of tools that can assist managers in making sound business decisions. OLAP is a powerful technology behind many Business Intelligence (BI) applications. It offers many capabilities for data discovery, report viewing, complex analytical calculations, and planning (Olap.com, n.d.). In other words, OLAP is a “computer-enhanced multidimensional analysis” (Achor, 2002). The term OLAP was created by E.F. Codd in 1993. According to Codd and associates, OLAP is made up of many speculative “what-if” and/or “why” data model scenarios conducted within the context of the specific historical basis (Codd, Codd and Salley, 1993). Under these scenarios, the values of major parameters are changed to show potential variances in “supply, production, the economy, sales, marketplace, costs, and/or other environmental and internal factors” (Codd, Codd and Salley, 1993, p.6). These variable groups or dimensions make up a base for the company’s planning, analysis and reporting activities (Bogue, 2005). OLAP tools do not keep individual transaction records in a row-by-column format, like relational databases. Instead, they store consolidated information in multidimensional cubes (Olap.com, n.d.). When necessary, analysts use operations called consolidation...

...ABSTRACT Online Analytical Processing is a powerful framework for the analysis of organizational data. OLAP is often supported by a logical structure known as a data cube, a multidimen- sional data model that offers an intuitive array-based per- spective of the underlying data. Supporting efficient index- ing facilities for multi-dimensional cube queries is an issue of some complexity. In practice, the difficulty of the in- dexing problem is exacerbated by the existence of attribute hierarchies that sub-divide attributes into aggregation layers of varying granularity. In this paper, we present a hierar- chy and caching framework that supports the efficient and transparent manipulation of attribute hierarchies within a parallel ROLAP environment. Experimental results verify that, when compared to the non-hierarchical case, very little overhead is required to handle streams of arbitrary hierar- chical queries.

INTRODUCTION Online Analytical Processing (OLAP) has become an im- portant component of contemporary Decision Support Sys- tems (DSS). Central to OLAP is the data cube, a multidi- mensional data model that presents an intuitive cube-like Permission...

...Application of OLAP to the Analysis of the Curriculum Chosen by Students Hua-long Zhao Department of Geography Dezhou University Dezhou Shandong 253023, China Zhl1970@dzu.edu.cn Abstract—With development of the scale of higher education, more and more data about curriculum chosen by students has been produced. This paper analyzes the application of data warehouse, on-line analytical processing and data mining on the analysis of curriculum chosen by students, accomplishes the design of data warehouse about universities curriculum chosen by students, extracts and transforms curriculum chosen by students data and then loads them into the data warehouse. This paper builds curriculum chosen by students multidimensional cube analysis data model by taking use of OLAP technology, and realizes the query, analysis and show of curriculum chosen by students multidimensional data, so it can analyze the curriculum's establishment situation from many angles, and serve the university teaching decision support system. (Abstract) Keywords-Data Warehouse, OLAP, Dimensional Table, Fact Table, Star Model. Ⅰ. INTRODUCTION Data warehouse is a new database technology that has rapidly developed since 1990s. It can serve the policy-maker well, and it is one of data congregations that have the features of facing theme, integration, variation with time and supporting decision. In the past more than 20 years, with the development and widespread application of database, enterprise has accumulated massive...

...Identifying Good or Bad Statements Anit Maharjan HUMN210-H5WW Meghan Roehll Franklin University 4th April, 2013 a. Nobody in the world today is really good. Yes, I have heard of good people, but not really good people. - Good statement. b. The world is not flat. Well, if you look at a map it is: - in what point of view - bad statement. c. I will need an extended period of laborious cogitation to assimilate the missive. This doesn't make any sense - bad statement. d. The number 2 is odd. Are we talking about an even number? I believe your confusion comes from the fact that 2 is a prime number, but it is still even. It is the only even number that is prime – false statement. e. If you believe in evolution, then your ancestors were filthy apes. There are two kinds of people in the world: - one is god prayer and the next is science believer. If you support the statement from the point of scientific theory of evolution by Darwin, then yes our ancestors are filthy apes, whereas if you think form the side of god’s prayer then the statement is false – good statement. f. Some swans are black. In this statement, I am not sure that some swans are black or not, all swans could be black or white – good statement. g. If you are a human, then you are a person. If you are an individual, then you are alive. Human is a person and of course the person becomes an individual and every individual breaths...

...Choices and Consequences The Number 1 choice is Jerry, the father, offers the best utilitarianism of hope and use of his life to help his children and family and the best longevity of life given he has essentially been healthy except for the damage done to his heart from the Steroids some 20 to 30 years earlier. His wife and children play no part in the decision in him getting the heart. It all has to do with his health, and ability to live a life after he receives it. And also some other facts which should be considered like life expectancy, importance, age etc. when deciding on whom to donate the heart to. He’s cause for damage to the heart was the steroids, of which he was unaware of the consequences of taking the steroids at the time he took so there wasn’t any sort of health irresponsibility known otherwise. His chances to live 10-15 more years are very high so it’s one point investing in him. He has a family to take care of, wife and the 3 kids who he has to support till they are on their feet and so forth. He also has been a good supporting father as he’s already being supporting their dreams career wise and the future. So my first choice with all confidence would be Jerry. The number 2 choice is Ozzie because as LONG as he does not get back on his old ways HE does hold out some hope on society as a whole as long he does NOT revert back and does good in society by helping out and he no longer does any drugs - he really can have a useful and a prosperous and productive...
