Include what database applications should be used: Microsoft® Access®, IBM® DB2®, Oracle®, and so on. Conclude by proposing improvements. For large organizations, restrict the scope of the paper to the department in which you work. The use of database in the business environment has become an integral part in business processing. According to an article, Database Evolution: Microsoft Access within an Organization's Database Strategy, Chung explains that databases are used in a variety of levels for various reasons: Enterprise level, Department level, Workgroup/Team Level and Individual/small groups. With these, database systems are used as data centers in order for companies to process data, whether customer transactions, storing information (business) or to maintain security. The most popular database used today is Microsoft Office Access, or which most know it as Microsoft Access. This was developed my Microsoft Corporation and can also be used as a “frontend” with other products as the “backend” table. Which means that all the data processing can be done by Microsoft SQL Server, a Microsoft product and other database applications, for example Oracle. Microsoft Access is the main database application used by our company (Affiliated Computer Service). Due to the nature of our business...

...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 requires more indexes...

...Global Trade of Wood and Paper Products Abstract Global trade of wood products is accelerating amid shifting regional production of raw materials. At the same time structural change is occurring in regional production and consumption of finished and semi-finished wood and paper products. Some countries which once were major net exporters of wood products, such as the United States, have become major net importers. Conversely, China, a country that not long ago was a major net importer of wood products, is increasingly dominant as an exporter of value-added wood products such as furniture. What are the reasons behind these shifts in sources of supply and demand for wood and wood products? Direct forces such as population growth and rising socio-economic levels drive demand for wood and paper products. Increasing purchasing power in developing economies empowers consumers, both private and public, to purchase homes, furnishings and accessories. Indirect factors, such promotion of wood, strengthen demand and translate to significant gains in consumption in some markets. Consciousness of climate change and the advantages of wood for products and energy is creating a new impetus for increasing wood products consumption, including wood-derived energy products. Government and industry policies are important market drivers. Government policies can support increased utilization of wood, or can restrict wood in construction when standards favor competitive building materials...

...Running 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...

...Data Warehouses Kevin Sloley Professor Dammlash Gebre CIS-111 Intro to Related Database Management Systems Due March, 2016 Outline the main differences between the structure of a relational database optimized for online transactions versus a data warehouse optimized for processing and summarizing large amounts of data. The primary difference between your application database and a data warehouse is that while the former is designed (and optimized) to record, the latter has to be designed (and optimized) to respond to analysis questions that are critical for your business. Application databases are OLTP (On-Line Transaction Processing) systems where every transaction has to be recorded, and super-fast at that. Consider the scenario where a bank ATM has disbursed cash to a customer but was unable to record this event in the bank records. If this started happening frequently, the bank wouldn't stay in business for too long. So the banking system is designed to make sure that every trasaction gets recorded within the time you stand before the ATM machine. This system is write-optimized, and you shouldn't crib if your analysis query (read operation) takes a lot of time on such a system. A Data Warehouse (DW) on the other end, is a database (yes, you are right, it's a database) that is designed for facilitating querying and analysis. Often designed as OLAP (On-Line Analytical Processing) systems, these databases contain read-only data that can be queried and analyzed far...

...implement and run, to allow for the development of structured and well organized programs, and to serve as a tool to teach the important concepts of computer programming. The program was named after a mathematician named Blaise Pascal. It was used as the primary language in the Apple Lisa and for the Mac in the early years of the computer. SQL SQL, which is short for, Structured Query Language, was designed by an IBM research center in 1974-1975. The Oracle Corporation introduced it as a commercial database system in 1979, the first time it was introduced. It has been a favorite query language for the use of database management systems for the microcomputer and mainframes, but is being supported by the PC database. C C was created at the Bell Laboratory in 1972 by Dennis Ritchie. It was created for the purpose in designing UNIX. Prolog Was created from 1971-1973 and was distributed in 1974-1975. It was created not as a programming language on purpose but as a tool for processing natural languages specifically French. It was created by Robert Pasero, Philippe Roussel, Alain Colmerauer, and Jean Trudel. Smalltalk Developed in the early 1970’s, at the Xerox Palo Alto Research Center. It was created by Alan Kay, Dan Engalls, Adele Goldberg, and Dave Robson. The five popular programming languages of the 1980’s are: 1983: Ada 1983: C++ 1985:...

...Systems Analysis and Design CIS 3512 Professor Setterlind July 6, 2014 Information Systems have been around for a long time, whereas, the term Information Technology is relatively new. The U.S. Postal Service could be considered an information system with sub-systems including logistics, and transportation. With a system of main post offices and community locations, the Postal Service is able to move letters and packages around the world in only a few days. Since the introduction of computers into the business industry, Information Systems focus on making use of technology to disseminate information. Information Technology could be considered a sub-system of Information Systems since the technology supports and enables the system through software and hardware development. The five main components of an information system are people, hardware resources, software resources, data resources, and network resources. (2010). People include the end-users and also the programmers, analysts, and other technical specialists that support the system. Hardware resources include the servers, client workstations, monitors, keyboards, and all other peripherals that interconnect them. Human interface devices allow users to input data to the system, which is translated into usable information. Software resources include the system operations programs, such as Windows, or Unix, and application software that are specific to a particular task, such as, word processing or finance. Included with software...
