Despite recent progress in information technology, health care institutions are constantly confronted with the need to adapt to the resulting new processes of information management and use.[1] Nusing information systems(INSs) are promoted as a technology supporting collaboration and improving health care decision making at the point- of –care and ultimately health care outcomes. An NIS contains data collection and intetration functionality for nurses and could be used as a part of an electronic health record(EHR) or in conjunction with an electronic medical record(EMR). NISs have the potential to increase nursing documentation completeness readability, and availability. NISs also provide the means to decrease double

Recent breaches of Personal Identifiable Information (PII) highlight the failure of technical mitigation to prevent external threats. Whenever you send personal information across the internet, be it passwords, credit card information or personal contact details, encryption stops others from seeing what you are doing. Data is jumbled up in a manner so that when it travels through the internet it is completely unreadable, this stops hackers who may intercept the data from seeing what you’re doing. Cryptography is the process which meres words with letter, numbers and images to be viewed by the public, while not revealing the meaning of the message. Once a message has been encrypted it is secure to transmit or to remain at rest. The

What are your major concerns about computer crime and privacy on the internet? What can you do about it? Explain.

E-business gives a competitive advantage to the company. However, it is also important for a business to know how the e-business is being used. The uses of e-business are for reengineering for internal business processes, enterprise collaboration systems to support communications, coordination and coordination among teams

Chapter 9: Global Information Systems Why go Global? –Customers demand integrated worldwide services. Example: shoe company. Prerequisites to the success of a global information system: -Clear understanding of factors such as customs, laws, technological issues, and local business needs and practices. Airline reservation systems- first large-scale interactive global system Global products-Products or services that have been standardized for all markets. Manufacturer might “regionalize” operations Globalization- important factor in purchasing and supply chain Global Information Systems at Rohm & Haas: Part of Dow Chemical Production units in many different countries Overhauled its global information system: By upgrading the

Health information systems and database technology continue to advance and grow and allow users to pull data and interconnect like ever before. The goal for this discussion is to better familiarize you with fundamental concepts in relation to database systems and relevant health information standards. We will also be comparing three of the top ten most purchased EHR systems for comparison, allowing you to understand the functionality of each system, as well as, the barriers to implementation.

A Corporation’s Information Technology department (IT) aids in making major decisions on financial, security, and technological tasks/projects. When the IT department and the business act together to do so, a business can run the most efficiently and economically achieving maximum profit levels. It was stated “It is not necessarily what you make in a factory that counts; its what you do with the information that you own that brings in the revenue”(Rasiah, par. 2). In essence, the IT department helps with all the information, technology, software, and data decision making in a company. This makes the department vital to the company’s success. However, if a company did not have or invest in an IT department, many things could go wrong inside

With 3.2 billion internet users [1] and 6.4 billion internet connected devices by 2016 [2], unprecedented amount of data is being generated and process daily and increasing every year. The advent of web 2.0 has fueled the growth and creation of new and more complex types of data which creates a natural demand to analyze new data sources in order to gain knowledge. This new data volume and complexity of the data is being called Big Data, famously characterised by Volume, Variety and Velocity; has created data management and processing challenges due to technological limitations, efficiency or cost to store and process in a timely fashion. The large volume and complex data is unable to be handled and/or processed by most current information systems in a timely manner and the traditional data mining and analytics methods developed for a centralized data systems may not be practical for big data.

The software and IT Services market is usually broken into two segments: Software, and IT Services, and is sometimes split into a third segment covering Internet and Cloud Software and Services. The software segment includes application software and systems such as security software, information management, software infrastructure, and enterprise applications. IT Services includes IT consulting, support, outsourcing, and processing. Internet and Cloud Software and Services include Infrastructure, Platform, and Software services.

Today’s world of computer systems are used by large set of individuals across organisations either collocated or distributed geographically. This has decreased the level of trust as compared to the past where there were small set of users entrusted in an organisation (Van der Geest G J, 2008) . In a bid to make sensitive data and infrastructure secured from unauthorized users, a security policy is developed by the system administrator of the organisation in other to control “who gets in”, “who does what” and “who sees what”. This duty has seemed to be one of the difficult problems faced by the admin and could turn out bad If not controlled properly (Kizza, 2009). However, due to differences in geographical
