Big data analytics is the use of advanced analytic techniques against very large, diverse data sets that include structured, semi-structured and unstructured data, from different sources, and in different sizes from terabytes to zettabytes.Big data is a term applied to data sets whose size or type is beyond the ability of traditional relational databases to capture, manage and process the data with low latency. Big data has one or more of the following characteristics: high volume, high velocity or high variety. Artificial intelligence (AI), mobile, social and the Internet of Things (IoT) are driving data complexity through new forms and sources of data. For example, big data comes from sensors, devices, video/audio, networks, log files, transactional applications, web, and social media — much of it generated in real time and at a very large scale.Analysis of big data allows analysts, researchers and business users to make better and faster decisions using data that was previously inaccessible or unusable. Businesses can use advanced analytics techniques such as text analytics, machine learning, predictive analytics, data mining, statistics and natural language processing to gain new insights from previously untapped data sources independently or together with existing enterprise data.

大數(shù)據(jù)分析是對非常大、多樣的數(shù)據(jù)集使用先進(jìn)的分析技術(shù)，這些數(shù)據(jù)集包括結(jié)構(gòu)化、半結(jié)構(gòu)化和非結(jié)構(gòu)化數(shù)據(jù)，來自不同的源，大小從TB到Zettabytes不等。大數(shù)據(jù)是一個用于數(shù)據(jù)集的術(shù)語，其大小或類型超出了傳統(tǒng)關(guān)系數(shù)據(jù)庫捕獲、管理和處理低延遲數(shù)據(jù)的能力。大數(shù)據(jù)具有以下一個或多個特征：高容量、高速或高多樣性。人工智能（AI）、移動、社會和物聯(lián)網(wǎng)（IOT）正通過新的數(shù)據(jù)形式和來源推動數(shù)據(jù)復(fù)雜性。例如，大數(shù)據(jù)來自傳感器、設(shè)備、視頻/音頻、網(wǎng)絡(luò)、日志文件、事務(wù)性應(yīng)用程序、網(wǎng)絡(luò)和社交媒體——其中大部分都是實(shí)時生成的，而且規(guī)模非常大。對大數(shù)據(jù)的分析允許分析師、研究人員和業(yè)務(wù)用戶使用以前無法訪問或無法使用的數(shù)據(jù)做出更好更快的決策。企業(yè)可以使用先進(jìn)的分析技術(shù)，如文本分析、機(jī)器學(xué)習(xí)、預(yù)測性分析、數(shù)據(jù)挖掘、統(tǒng)計(jì)和自然語言處理，獨(dú)立地或與現(xiàn)有企業(yè)數(shù)據(jù)一起從以前未開發(fā)的數(shù)據(jù)源獲得新的見解。
