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?

What is Big Data? This data is mainly generated in terms of photo and video uploads, message exchanges, putting comments etc. Types Of Big Data Following are the types of Big Data: Structured Unstructured Semi-structured Structured Any data that can be stored, accessed and processed in the form of fixed format is termed as a 'structured' data.

Over the period of time, talent in computer science has achieved greater success in developing techniques for working with such kind of data where the format is well known in advance and also deriving value out of it.

However, nowadays, we are foreseeing issues when a size of such data grows to a huge extent, typical sizes are being in the rage of multiple zettabytes. Do you know? Looking at these figures one can easily understand why the name Big Data is given and imagine the challenges involved in its storage and processing. In addition to the size being huge, un-structured data poses multiple challenges in terms of its processing for deriving value out of it.

A typical example of unstructured data is a heterogeneous data source containing a combination of simple text files, images, videos etc. Now day organizations have wealth of data available with them but unfortunately, they don't know how to derive value out of it since this data is in its raw form or unstructured format.

We can see semi-structured data as a structured in form but it is actually not defined with e. Example of semi-structured data is a data represented in an XML file. OLTP systems are built to work with structured data wherein data is stored in relations tables. Size of data plays a very crucial role in determining value out of data.

Also, whether a particular data can actually be considered as a Big Data or not, is dependent upon the volume of data. Variety refers to heterogeneous sources and the nature of data, both structured and unstructured. During earlier days, spreadsheets and databases were the only sources of data considered by most of the applications. Nowadays, data in the form of emails, photos, videos, monitoring devices, PDFs, audio, etc.

This variety of unstructured data poses certain issues for storage, mining and analyzing data. How fast the data is generated and processed to meet the demands, determines real potential in the data.

Big Data Velocity deals with the speed at which data flows in from sources like business processes, application logs, networks, and social media sites, sensors, Mobile devices, etc. The flow of data is massive and continuous.

Benefits of Big Data Processing Ability to process Big Data brings in multiple benefits, such as- Businesses can utilize outside intelligence while taking decisions Access to social data from search engines and sites like facebook, twitter are enabling organizations to fine tune their business strategies.

Improved customer service Traditional customer feedback systems are getting replaced by new systems designed with Big Data technologies. In these new systems, Big Data and natural language processing technologies are being used to read and evaluate consumer responses. In addition, such integration of Big Data technologies and data warehouse helps an organization to offload infrequently accessed data.

Bigdata is a term used to describe a collection of data that is huge in size and yet growing exponentially with time.

Big Data analytics examples includes stock exchanges, social media sites, jet engines, etc. A Partition is a hard drive section that is separated from other parts. It enables you to divide What is UNIX? KeepVid was a free video downloading software that enables you to store any video clips on your PC Home Testing. Must Learn! Big Data. Live Projects. Introduction, Types, Characteristics, Example. A Podcast Hosting Platform is a special service that stores media files and delivers them to Linux is a clone of UNIX, the multi-user operating system which can be accessed by many users It is a newly emerging term in the IT field, which is

What is BIG DATA? Introduction, Types, Characteristics, Example

If you're studying for a statistics exam and need to review your data types this article will give you a brief overview with some simple examples. In short: quantitative means you can count it and it's numerical think quantity - something you can count. Qualitative means you can't, and it's not numerical think quality - categorical data instead. There's one more distinction we should get straight before moving on to the actual data types, and it has to do with quantitative numbers data: discrete vs. Discrete data involves whole numbers integers - like 1, , or 9 that can't be divided based on the nature of what they are.

Fundamental Data Types, Declarations, Definitions and Expressions

In computer science and computer programming , a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support basic data types of integer numbers of varying sizes , floating-point numbers which approximate real numbers , characters and Booleans. A data type constrains the values that an expression , such as a variable or a function, might take.

Home Consumer Insights Market Research. Qualitative data is defined as the data that approximates and characterizes. Qualitative data can be observed and recorded.

Metadata is " data that provides information about other data". Many distinct types of metadata exist, including descriptive metadata , structural metadata , administrative metadata , [2] reference metadata and statistical metadata. Metadata has various purposes.

Secondary data refers to data that is collected by someone other than the primary user. Secondary data analysis can save time that would otherwise be spent collecting data and, particularly in the case of quantitative data , can provide larger and higher-quality databases that would be unfeasible for any individual researcher to collect on their own. However, secondary data analysis can be less useful in marketing research, as data may be outdated or inaccurate.

 Ну вот, наконец-то! - вскрикнул Джабба.  - Это и есть их вес. - Тридцать секунд.

Это же крайне недальновидно. Ты говоришь, что наше дерьмовое правительство исходит из высших интересов людей. Но что будет, если какое-нибудь будущее правительство станет вести себя. Ведь эта технология - на вечные времена. Сьюзан слушала его безучастно, от воя сирены у нее закладывало уши.

Стратмор поднял руку, давая понять, что ему нужно подумать. Сьюзан опасливо перевела взгляд в сторону люка. Его не было видно за корпусом ТРАНСТЕКСТА, но красноватое сияние отражалось от черного кафеля подобно огню, отражающемуся ото льда.

Запускайте видеозапись. ГЛАВА 117 - Трансляция видеофильма начнется через десять секунд, - возвестил трескучий голос агента Смита.

Странные очки, подумал Беккер, увидев проводок, который тянулся от ушных дужек к коробочке, пристегнутой к брючному ремню. Но он настолько устал, что ему было не до любопытства. Сидя в одиночестве и собираясь с мыслями, Беккер посмотрел на кольцо на своем пальце.

Мы ищем число, а не произвольный набор букв. - Четыре умножить на шестнадцать, - спокойно сказал Дэвид.  - Вспомни арифметику, Сьюзан. Сьюзан посмотрела на Беккера, наблюдавшего за ней с экрана.

Посверкивая в красноватом свете туннельных ламп, перед ними возникла стальная дверь. Фонтейн набрал код на специальной углубленной панели, после чего прикоснулся к небольшой стеклянной пластинке. Сигнальная лампочка вспыхнула, и массивная стена с грохотом отъехала влево.
