A database management system (DBMS) is a collection of programs that enables you to store, modify, and extract information from a database. There are many different types of database management systems, ranging from small systems that run on personal computers to huge systems that run on mainframes.
Information technology is introducing changes for which laws and rules of acceptable conduct have not yet been developed. Increasing computing power, storage, and networking capabilities--including the Internet--expand the reach individual and organizational actions and magnify their impacts. The ease and anonymity with which information is now communicated, copied, and manipulated in online environments pose new challenges to the protection of privacy and intellectual property. The main ethical, social, and political issue raised by information systems center around information rights and obligations, property rights and obligations, accountability and control, system quality, and quality of life. 1.Ethical issues: Intellectual property rights, electronic monitoring of employees and data utilization; 2.Cultural issues: Assimilation of emerging technologies, developing trust, power asymmetry, policy implementation, and social environments; 3.Human interaction issues: re
What is a Value Chain Analysis? The value chain also known as Porter’s Value Chain Analysis is a business management concept that was developed by Michael Porter . In his book Competitive Advantage (1985), Michael Porter explains Value Chain Analysis; that a value chain is a collection of activities that are performed by a company to create value for its customers. Value Creation creates added value which leads to competitive advantage. Ultimately, added value also creates a higher profitability for an organization. Porter’s Value Chain Analysis The strength of the Porter’s Value Chain Analysis is its approach. The Porter’s Value Chain Analysis focuses on the systems and activities with customers as the central principle rather than on departments and accounting expense categories. This system links systems and activities to each other and demonstrates what effect this has on costs and profit. Consequently, it (Value Chain Analysis) makes clear where the sources of val
Components of CPU and their functions: CPU or Central processing unit is the brain of the computer system. Functions of CPU varies from data processing to controlling input-output devices. Each and every instruction no matter how complex or simple, it has to go through the CPU. In this article we will learn various components of CPU and their functions. So, let us say we press a key on the keyboard and it instantly appears on our computer monitor so the CPU of the computer is what makes this possible. The central processing unit is also responsible for storing data or information, intermediate results and instructions in the memory system. It also controls the operations of all other parts of the computer system. Functions of a CPU: CPU generally performs the arithmetical and logical operations, controlling of different input-output devices. These operations are performed based on some predefined algorithms and ins
