Information Systems Essentials

The first chapter talks about the information age in which individuals live. Precisely, people are living in the digital age and technology is influencing everything we do. In this chapter, I learned about management information system, which entails using people, information, and information technology to achieve the organizational goals. Similarly, I learned that the quality of information is characterized by validity, form, location and timeliness. Technology literacy is significant since individuals need to understand the information about the technology they are applying. Ethical responsibilities encompass following principles and standards that protect one and the organization against actions of others.

Chapter two talks about information technology and gaining a competitive advantage. I learned about a supply chain management system. It refers to a technologically driven system that automates the tracking of inventory and information to support activities of the supply chain management among businesses. With the just-in-time method, companies can produce and deliver products when the customer request them. Regarding competitive opportunities, firms that incur lower costs tend to offer lower prices to consumers thus increasing market share and revenue. IT culture entails how the organization structures the IT function and its philosophical approach to IT.

Chapter three illustrates databases and data warehouses. Organizations use databases to store basic and transaction-oriented information. The relational database encompasses the use of two-dimensional tables to store information. A data warehouse refers to a store of information that the organization uses to develop business intelligence to support analysis activities and decision-making roles. Features of data warehouses are that they are multidimensional and support decision-making. With data mining tools, one can use software tools to inquire information in a data warehouse. Additionally, I learned that information ownership is essential, and the success of the organization depends on the ability to organize and manage information.
