Abstract The “big data” and “big data mining” are the terms which are growing on increasing as the use of internet, smartphones and the networking technologies are increasing. The data generation rate get doubled or tripled in some recent years. So to make proper usefulness of this vast amount of data, mining from big data has almost immediately followed up as an emerging interrelated research area. This paper provides an overview of big data mining along with the challenges that one has to face
the managing the activities of data, for datas that has been in use for the purpose of long term research ensuring the availability of data for further reuse and preservation, it also deal with the extraction of important information from scientific texts including extraction from articles, biological database. Searching of other datas with the help of given data, sharing of data, data transfer, visualization of data, privacy if the information contained in the data is some of the modern day
measured in petabytes or Exabyte because of its large and complex digital datasets. Databases and analytics have been used in organization and firm last couple of decades. The transaction are stored in data warehouses and will be analyzed with data-mining algorithms to extract insights. But, now big data are different and become a new phenomenon that gives more good advantages for every organization. Today, big data have more and more different kinds of data. For example in the past, structured data
