Over the past era, there have been a lot of efforts and studies are carried out in growing proficient tools for performing various tasks in big data. Recently big data have gotten a lot of publicity for their good reasons. Due to the large and complex collection of datasets it is difficult to process on traditional data processing applications. This concern turns to be further mandatory for producing various tools in big data. Moreover, the main aim of big data analytics is to utilize the advanced analytic techniques besides very huge, different datasets which contain diverse sizes from terabytes to zettabytes and diverse types such as structured or unstructured and batch or streaming. Big data is useful for data sets where their size or type is away from the capability of traditional relational databases for capturing, managing and processing the data with low-latency. Thus the out coming challenges tend to the occurrence of powerful big data tools. In this survey, a various collection of big data tools are illustrated and also compared with the salient features.

IG data is avast quantity of data which extracts values by the process of capturing and analysis, this can be possible by innovative architectures and technologies. Nowadays from the platform of traffic management and tracking personal devices such as Mobile phones are useful for position specific data which emerges as novel bases of big data. Mainly the Big data have developed to increase the use of data demanding technologies for it. By using prevailing traditional techniques it is very challenging to achieve effective analysis of the huge size of data. Meanwhile, on the market, big data have become the latest imminent technology, which can serve vast profits to the business organizations.

This becomes essential because it contains several issues and challenges related in bringing and adapting, which need to be understood in this technology. The concept of big data deals with the datasets which continues to develop rapidly whereas that becomes tough to handle them by using the current concepts and tools in database management. Data capture, sharing, analytics, search, storage, visualization, etc., is the related difficulties in big data. Many challenges can be forwarded due to the several properties of big data like variety, velocity, variability, volume, value and complexity. Scalability, real-time analytics, unstructured data, fault tolerance, etc., is the several challenges included in huge data management.

Obviously the amount of data stored in various sectors can vary in the data stored and created, i.e., images, audio, text information etc., from one industry to another. From the practical perspective, the graphical interface used in the big data analytics tools leads to be more efficient, faster and better decisions which are massively preferred by analysts, business users and researchers.

Recently the trade press has been filled with news of the revolution of “cluster computing”. This paradigm entails harnessing large numbers of (low-end) processors working in parallel to solve a computing problem. In effect, this suggests constructing a data center by lining up a large number of low-end servers instead of deploying a smaller set of high-end servers. With this rise of interest in clusters has come a proliferation of tools for programming them. One of the earliest and best known such tools in MapReduce (MR) [8]. MapReduce is attractive because it provides a simple model through which users can express relatively sophisticated distributed programs, leading to significant interest in the educational community. For example, IBM and Google have announced plans to make a 1000 processor MapReduce cluster available to teach students distributed programming.

Given this interest in MapReduce, it is natural to ask “Why not use a parallel DBMS instead?” Parallel database systems (which all share a common architectural design) have been commercially available for nearly two decades, and there are now about a dozen in the marketplace, including Teradata, Aster Data, Netezza, DATAllegro (and therefore soon Microsoft SQL Server via Project Madison), Dataupia, Vertica, ParAccel, Neoview, Greenplum, DB2 (via the Database Partitioning Feature), and Oracle (via Exadata). They are robust, high performance computing platforms. Like MapReduce, they provide a high-level programming environment and parallelize readily.

Though it may seem that MR and parallel databases target different audiences, it is in fact possible to write almost any parallel processing task as either a set of database queries (possibly using user defined functions and aggregates to filter and combine data) or a set of MapReduce jobs. Inspired by this question, our goal is to understand the differences between the MapReduce approach to performing large-scale data analysis and the approach taken by parallel database systems. The two classes of systems make different choices in several key areas. For example, all DBMSs require that data conform to a well-defined schema, whereas MR permits data to be in any arbitrary format. Other differences also include how each system provides indexing and compression optimizations, programming models, the way in which data is distributed, and query execution strategies.

The purpose of this paper is to consider these choices, and the trade-offs that they entail. We begin in Section 2 with a brief review of the two alternative classes of systems, followed by a discussion in Section 3 of the architectural trade-offs. Then, in Section 4 we present our benchmark consisting of a variety of tasks, one taken from the MR paper [8], and the rest a collection of more demanding tasks. In addition, we present the results of running the benchmark on a 100-node cluster to execute each task. We tested the publicly available open-source version of MapReduce, Hadoop [1], against two parallel SQL DBMSs, Vertica [3] and a second system from a major relational vendor. We also present results on the time each system took to load the test data and report informally on the procedures needed to set up and tune the software for each task.

Big data analytics is where advanced analytic techniques operate on big data sets. Hence, big data analytics is really about two things—big data and analytics—plus how the two have teamed up to create one of the most profound trends in business intelligence (BI) today. Let’s start by defining advanced analytics, then move on to big data and the combination of the two.

Current world is the world of data. We have data all around us. This data is huge in volume and being generated exponentially from multiple sources like social media (Facebook, Twitter etc.) and forums, mail systems, scholarly as well as research articles, online transactions and company data being generated daily, various sensors' data collected from multiple sources like health care systems, meteorological department, environmental organizations etc.

Data science is an emerging field which intersects data mining, machine learning, predictive analytics, statistics, and business intelligence. The data scientist has been coined the “sexiest job of the 21st century” (Davenport & Patil, 2012). The data science field is so new that the U.S. bureau of labor and statistics does not yet list it as a profession; yet, CNN’s Money lists the data scientist as #32 on their best jobs in America list with a median salary of $124,000 (Money, 2015). Fortune lists the data scientist as the hot tech gig of 2022 (Hempel, 2012).
