An introduction to data and information
Information can be thought of as the resolution of uncertainty ; it is that which answers the question of "What an entity is" and thus defines both its essence and the nature of its characteristics. The concept of information has different meanings in different contexts. Information is associated with data. The difference is that information resolves uncertainty. Data can represent redundant symbols, but approaches information through optimal data compression. Information can be transmitted in time, via data storage , and space, via communication and telecommunication. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
Computer - Data and Information
Data can be defined as a representation of facts, concepts, or instructions in a formalized manner, which should be suitable for communication, interpretation, or processing by human or electronic machine. Information is organized or classified data, which has some meaningful values for the receiver. Information is the processed data on which decisions and actions are based. Data processing is the re-structuring or re-ordering of data by people or machine to increase their usefulness and add values for a particular purpose. Data processing consists of the following basic steps - input, processing, and output. These three steps constitute the data processing cycle.

Data are characteristics or information , usually numeric, that are collected through observation. Although the terms "data" and "information" are often used interchangeably, these terms have distinct meanings. In some popular publications, data are sometimes said to be transformed into information when they are viewed in context or in post-analysis. Data are used in scientific research , businesses management e. Data are measured , collected and reported , and analyzed , whereupon it can be visualized using graphs, images or other analysis tools.
Before we go to introduction to Big Data, you first need to know What is Data? The quantities, characters, or symbols on which operations are performed by a computer, which may be stored and transmitted in the form of electrical signals and recorded on magnetic, optical, or mechanical recording media. Big Data is a collection of data that is huge in volume, yet growing exponentially with time. Big data is also a data but with huge size. In this tutorial, you will learn, What is Data?
Data analysis is a process of inspecting, cleansing , transforming , and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science, and social science domains. In today's business world, data analysis plays a role in making decisions more scientific and helping businesses operate more effectively. Data mining is a particular data analysis technique that focuses on statistical modeling and knowledge discovery for predictive rather than purely descriptive purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing mainly on business information.
