Explain computer virus, damage and computer contaminant and mischief.  Computer Virus Computer virus means any computer instruction, information, data or programme that destroys, damages, degrades or adversely affects the performance of a computer resource or attaches itself to another computer resource and operates when a programme, data or instruction is executed or some other event takes place in that computer resource (Section 43,explanation (III)). Example of viruses are 'I love you' virus. The cousins of the virus and contaminants are bugs, worms, logic bombs and trojan horse. They destroy the computer systems, programs and the data residing therein. Damage "Damage" means to destroy, alter, delete, add, modify or rearrange any computer resource by any means (Section 43, explanation (IV)). Computer contaminant "Computer contaminant" means any set of computer instructions that are desioη το modify, destroy, record, transmit data or programs residing with...

Explain different phases in development of business intelligence system. Answer: Phases in the development of Business Intelligence System: Analysis : During the first phase, the needs of the organization relative to the development of a business intelligence system should be carefully identified. This preliminary phase is generally conducted through a series of interviews of knowledge workers performing different roles and activities within the organization. It is necessary to clearly describe the general objectives and priorities of the project, as well as to set out the costs and benefits deriving from the development of the business intelligence system. Design : The second phase includes two sub-phases and is aimed at deriving a provisional plan of the overall architecture, taking into account any development in the near future and the evolution of the system in the mid-term. First, it is necessary to make an assessment of the existing information infrastructure...

What is bi cycle These four stages are the “business intelligence cycle.” It starts with defining objectives, proceeds to gathering and organizing information, analyzing it, and setting parameters for measuring and monitoring business performance going forward. Phase 1: Setting Clear Objectives The effective use of BI begins with an awareness that BI is fundamentally different from reporting and has strategic implications if it is used to its full potential. At the outset of a BI project (and on a periodic basis thereafter), business leaders should define the playing field in which they mean to operate. In many organizations, the initial focus for BI is on understanding the company’s existing customers, especially with respect to their buying behavior. Others may choose to zero in on sales performanc Phase 2: Gathering and Organizing Data Whatever your company’s top priorities may be, it’s helpful to brainstorm a list of potential questions around those topics. Ultimately, ...

What is business intelligence artictecture Business intelligence (BI) architecture is a framework that organizations use to support their business intelligence and analytics applications. It's the infrastructure that companies deploy to support all stages of the BI process . BI architecture includes:  1)Defining data collection streams 2)Information administration 3)All the technology that supports business intelligence 4)Technology standards and data management and analytics practices 5)Specific platforms and tools that will be deployed BI architecture provides a blueprint for how an organization will go about its BI initiatives. It also makes suggestions for activities that would improve corporate performance.  BI architects often have a bachelor's degree in computer science or a related technological degree

What is bi its features Business intelligence (BI) is a broad term that uses software to combine data mining, data visualization, and other tools and techniques to help organizations make data-driven decisions. BI uses software to analyze data sets and present findings in reports and dashboards. It can include: Data mining, Process analysis, Performance benchmarking, Descriptive analytics.  BI can help users draw conclusions from data analysis. Data scientists can use advanced statistics and predictive analytics to discover patterns and forecast future patterns.  Some features of BI tools include:  Increased accuracy More real-time data Improved collaboration Enhanced AI integration Greater scalability Ad hoc reporting Embedding and white labeling capabilities BI can also be used to manage inventory and warehouse activity. It can provide the ability to see how much stock is on hand and the sales history of that stock.
