The BDA pose the competency for firms to achieve or cherished an insights of large data extracted in different sources, of which IoT enables the sensors integration, Bluetooth and identification of radio frequency within a real-world environment enabled by a well networked services (Hashem & Anuar 2016). On daily basis, there are a number of profit-making applications cause big data (Venkatram ,et al. 2017) within the smart firms; for example ERP (i.e. payments and purchases), CRM (customers, relationships, offers and segmentation etc.) and web technologies (i.e. web logs).
The Big data principally designates large data sets i.e. Terabytes headed for Exabyte’s involving unstructured complex heterogeneous source as smartphone applications, sensor, political science, social media along with Internet based tools of which demands unique advanced technologies to collect, store, analyze, control and envision or visualize, its growth was estimate to be 25 billion by 2015 (Acharjya ; P, 2016). For instance, Facebook holds data of more than 500 terabytes each day comprising of updated status, likes, posts and uploaded photos (Xu, Frankwick, ; Ramirez, 2015). According to Katal, Wazid, ; Goudar (2013) organization experience rapid data from heterogeneous sources and varied formats (such as text, image, voice or raster).The data sources are but not limited to social media: tweets from Twitter, stories and follows from Instagram, likes and updates from Facebook, Transactional databases, comments from Blogs, videos from YouTube and etc. growing at a huge speed as a consequence experiencing a challenge in handling such enormous volume of data. The Big data are mainly characterized by 5 V’s properties: Variety, Volume, velocity, veracity and value (Akter & Wamba 2016; Katal, Wazid, & Goudar, 2013).
According to Power (2014) describe big data as ‘high-volume, high-velocity and high-variety information assets that demand cost-effective, innovative forms of information processing for enhanced insight and decision-making’. Based on a researcher International Data Corporation (IDC), express big data as data sets whose attributes make it impossible for current databases and architectures to be stored as well as managed. International Data Corporation insinuates data technologies ‘a new generation of know-hows and architectures designed to extract value economically from very large volumes of a wide variety of data by enabling high-velocity capture, discovery in addition to analysis’. (1).Variety: The data gathered from different sources such as social media, web pages, e-mails etc. of which include structured, semi structured and unstructured data (Akter & Wamba 2016; Schroeck, et al. 2012). Power ( 2014) signifies variety as digital format of numerous formats take account of photos, email and text documents’;(2)Volume: The organization are able to generated user data from internet .The internet regarded internet of things (IOT) bring about Big Data for instance researchers are initiating contemporary knowledge domain sites as collaborative forums, blogging and streaming of videos on top of e-commerce platforms or e-government sites of which acts as digital setting designed for business operations online hence contributes to an immense data volumes regarded as Big Data (Katal, Wazid, ; Goudar, 2013).
The (3) velocity implies meaning data are generated constantly at a rapid speed from internet and social media constantly stored in a database of which will be greatly becoming large data. Velocity represents the speed at which data is collected, processed and analyzed at real time (Akter ; Wamba 2016). (4)Veracity refers to the reliability, truthfulness and accuracy of mined big data (Akter ; Wamba 2016). Moreover, necessitates data warehouses scrutinized meant for authenticity, truthfulness, accuracy and reliability thus collection, preparation and cleaning processes is needed to audit and examined all the data sources. (5)Value: The value refers to the informational benefits (Akter ; Wamba 2016) achieved after data mining. To certify credibility, consistency along with accuracy, cleaning and integration of data are key on parameters (for instance naming conventions, attribute measures, structures encoding etc.) amid different data sources (Silahtaro?lu ; Alayoglu, 2016).
