Information System in Business Question 1 Assuming that you are the data analyst on the project team building a data warehouse for a company of your choice, list the possible data sources from which you will bring the data into your data warehouse. State clearly any assumptions that you will make. Data warehouse, defined as a repository of the companys data stored in an electronic format (A Definition of Data Warehousing 2008). All data warehouses are aimed to facilitate reporting and analysis.
Data warehouse architecture comprises of several important layers, - operational database layer, which is the source data for data warehouse, informational access layer (all information that was accessed for reporting and analysing, as well as all possible tools necessary for reporting and analyzing the obtained data), data access layer (the interface between the operational and informational layers), and metadata layer (the data directory). So, data warehouse usually administers data collected from various multiple sources. The sources, obviously, depend on the type of data warehouse, the specific requirements of the company, as well as the purpose, for which the data is collected within the specific organization. Lets examine the possible data sources for data warehouse for health organization. As far as organization deals with the health and human services, there should be several required data sources, which should be classified and categorized accordingly to facilitate the process of data collection. First, demographic data may include U.
S. Census 2000 Data, the statistic data from National Center for Health Statistics Births and Infant Deaths, with statistic related to the infant mortality rates, and low birth rates, and the information from Claritas, Inc. population estimates for 2004 which was calculated by means of proprietary algorithms based on information from the U. S.
Census 2000 Data. Spatial data sources may include but not limited to Primary Care Service Areas, Congressional Districts and HRSA-specific spatial data. Health system information will include all types of information from Centers for Medicare & Medicaid Services (CMS), and provider of Service File, Online Survey and Certification Reporting System (OSCAR) database. The data collected from these sources will include important characteristics for skilled nursing facilities, Medicare- approved hospitals, as well as health agencies, home health agencies, and other kinds of health-related facilities. Finally, the last but not the least source of data may include Health Professional Shortage Areas data, National Health Service Corps data, Medically Underserved Area/Population (MUA/P) data, etc. Question 2 - To what extent do traditional businesses help us to understand the way in which e-commerce is carried out?
How do you see the benefits of databases built within e-commerce? (e. g. a business website with built-in databases) With the emergence of internet technologies and the development of e-commerce the way in which business can be carried out has drastically transformed. Traditional businesses, for example, retailing businesses or other type of business requiring the shop space and professional sales personnel may be supplanted by the internet website. The appearance of e-commerce and internet allow the companies to create online shops and make the process of sales easier, as the customers can make the purchases in comfort, and the purchases will be delivered to them immediately (E-commerce and Electronic Transaction Act n. d. ).
The collecting, processing and use of the data related to the companys business operations are also very important to the companys success. With the emergence of e-commerce the companies get the possibility to have a business website with built-in databases, enabling them to do all possible functions, ranging from customer mailing lists kept and managed appropriately to other important business benefits. Various types of built-in databases can be used for various business needs. Finally, some of the most important benefits include the possibility to reduce the amount of time the company needs to spent for data management, the possibility to analyze data in a variety of ways, the possibility to promote a more disciplined and thorough approach to managing data, to turn disparate data into a valuable resource for the company, and to enhance the consistency and quality of the information in the database.
Question 3 - The need to effectively manage content of all types and particularly unstructured content has recently come into sharp focus. Enterprise Content Management technologies cover a broad set of capabilities. With the help of examples name and briefly explain three of such capabilities. Enterprise Content Management technologies help the companies to lower costs, to enhance productivity and business operations, and to ensure that all company's communications in all possible mediums are consistent. With the help of Enterprise Content Management technologies the companies also share data more effectively, enabling the companies to get the right data, to the right people, in the right form and at the right moment. Basically, the ECM is defined as the set of technologies used to capture, manage, store, preserve and deliver content and various documents related to the companys organizational processes (AIIM, The ECM Association 2008).
In such a way, the Enterprise Content Management technologies cover a wide set of capabilities, namely, capture, manage, store, preserve and deliver. Capture" implies the components and functionalities necessary to generate, capture, prepare and process all kind of data (electronic and analogue information). This may range from the simplest forms and levels, like simple information capture to the most complex data preparation with the use of automatic classification. The components of the "capture category are also referred to as input components. Manual generation and capture of data may include various forms of data, ranging from traditional paper documents to documents in electronic format, forms, emails, video, or multimedia objects. Another type of capture, semi-automatic or automatic capture may involve the use of xml or edi documents, EPR or business applications, to mention a few.
The "manage capability allows the companies manage, process and use data more effectively. They may include various types of databases for administration and retrieval of information, and various access authorization systems. The major aim of the Enterprise Content Management system, in these terms, is to provide these components (capture and manage) as a service for all solutions like document management, web content management, collaboration, records management, workflow, and business process management. The third, but not the last capability of the Enterprise Content Management system is storage.
It can be used to store the required information on a temporary basis, or on a permanent basis. It can be also used for the temporary storage of data, if the company has no need to archive it. Store components can be classified into three main categories - repositories (used as storage locations), library services (administration components required for the repositories), and storage technologies. The examples of repositories are file systems, content management systems, databases, and data warehouses. Library services are responsible for the process of taking and storing data from "capture" and "manage" components, and, finally, the storage technologies used to store information may include Read and Write Magnetic Online Media (hard drives, Storage Area Networks, etc), magnetic tape, or digital optical media (e.
g. CD-R, CD/RW, DVD, MO, etc) Bibliography A Definition of Data Warehousing. 2008. web (accessed April 17, 2008). AIIM, The ECM Association. 2008.
