Let’s start by understanding:
What Is Big Data?
Big Data is primarily a huge volume of data that arrives at high speed and has different sources and formats. The three V’s that characterizes data as big data are:
- High Volume of data (that can be the size of terabytes or petabytes)
- High Velocity, and
- Different Varieties of data sources and formats
Big data broadly falls under three main classes: Structured, Semi-Structured, and Unstructured Data.
Structured data can be used in its original form. It is highly specific, can be processed, stored, and retrieved in a fixed predefined format. Examples are employee or student records in relational data.
Unstructured data does not have a specific format or form and can collect different data types. It takes more processing power and time to analyze the unstructured data. Some examples are text files, logs, emails, survey reports, sensor data, videos, audio recordings, social media-generated data, images, and location coordinates.
Semi-Structured data is a combination of both structured and unstructured data. Such data can have a properly defined format and yet cannot be distinguished to sort and preprocess. Examples are: extensible markup language (XML) files and radio-frequency identification (RFID) data.
The traditional methods have limitations in handling such complex, massive datasets; hence we need specific tools and techniques to manage such kinds of data, which falls under Big Data analytics.

Moving on to the other tools…
Massively Parallel Processing (MPP) Tools
Massively Parallel means employing a large number of computer processors (or separate computers) to perform a set of coordinated computations in parallel simultaneously.
In the MPP system, the data and the processing power are split among several different servers (or also called the processing nodes), where each of these servers is independent. The servers are separated in the sense that these do not share the operating system and memory.
This way, MPPs can scale horizontally to add more resources to perform the task and not need to upgrade to expensive servers individually, which means scaling vertically.
So, MPP is a storage structure designed to handle the coordinated (or homogenous) processing tasks by multiple processors parallelly. MPP can have up to 200 or more processors, and these are all interconnected with a high-speed network. These nodes can connect via messaging each other.
Teradata is one of the most popular Relational Database Management System (RDBMS) developed by the company named Teradata itself.
- It is a massively parallel open processing system for developing large scale data warehousing applications.
- It is highly scalable and capable of handling large volumes of data (more than 50 petabytes of data).
- It offers support to multiple data warehouse operations at the same time to different clients.
- It is both linearly and horizontally scalable. It can scale up to a maximum of 2048 nodes (i.e., by adding nodes) that increase system performance.
- It can run on Linux, UNIX, and Windows server platforms.
- It is based on the MPP architecture that can divide the large volumes of data into smaller processes across the entire system. All these smaller processors execute in parallel to ensure the task completes quickly. Hence, Teradata has unlimited parallelism.
- Teradata can connect to channel-attached systems such as a mainframe or network-attached systems.
- Teradata supports standard SQL to interact with data stored in the database. It also provides its own extension.
- It has many robust loads and unloads utilities to import and export data from and to the Teradata system, such as FastLoad, MultiLoad, FastExport, and TPT.
- Teradata has a low cost of ownership. It is easy to set up, maintain and administrate.
- It automatically distributes data across processors (into the disks) evenly without any manual intervention.
- All of its resources: Teradata Nodes, Access Module Processors (AMPs), and the associated disks work independently. Its architecture hence is also known as Shared Nothing Architecture.
- Teradata has a very mature parallel optimizer. It can handle up to 64 joins in a query!
The Netezza Performance Server data warehouse system includes SQL that is known as IBM Netezza Structured Query Language (SQL). We can use SQL commands to create and manage the Netezza databases, user access, and permissions for the database. It can also be used to query and modify the contents of the databases.
- IBM Netezza, which is part of IBM PureSystems, is an expert integrated system with in-built expertise, integrated by design and simplifies the user experience.

- Like Teradata, SAP HANA reduces the cost for IT companies to store and maintain large data volumes. It is very cost-effective to own.
MPP databases are in tabular or columnar format that does allow tasks or queries to be processed; however, there is a limitation of MPP. MPPs do not support unstructured data, and even some of the structured databases such as MySQL or PostgreSQL data require some processing to fit the MPP framework. This leads us to the second type of database: the No-SQL database.
NoSQL Data Stores Tools
Not only SQL, or in other words, No-SQL is the database to handle the unstructured data. It is the non-relational database design providing flexible and dynamic schemas for storage and retrieval for such data. A non-relational database means the data is not tabular and does not use structured query language (SQL).
A quick summary differentiating between SQL and No-SQL databases:
|Type of data||SQL is used for structured data having multi-row transactions.||No-SQL is used for unstructured data such as documents or JSON.|
|Type of databases||SQL databases are relational.||No-SQL databases are non-relational.|
|Schema||SQL uses structured query language and has a predefined schema.||No-SQL databases have dynamic schema.|
|Form of data storage||SQL database stores data in tabular form.||No-SQL databases store data in documents, key-value, graph, or wide-column form.|
The prominent big data analytics tools that use non-relational databases are MongoDB, Cassandra, Oracle No-SQL, and Apache CouchDB. We’ll dive into each one of these and cover their respective features.
Founded in 2007, MongoDB is an open-source No-SQL database.
- It supports heterogeneous data and is schema-less. The dynamic schemas mean we can change the blueprint (i.e., the data schema) without changing the existing data.
- The database is developed for high performance, high availability, and easy scalability.
- It is based on the key-value pair (i.e., on BSON format, a binary form of JSON) for document storage and does not use any complex joins.
- MongoDB has the feature of query caching and its long internal storage memory that speeds up the data retrieval from the database.
- It is flexible as we can easily change columns or fields without impacting the existing rows or application performance.
- MongoDB is manageable and user-friendly, meaning this database does not need a data administrator; hence it can be used both by the developers and the administrators.
- Unlike the relational database RDBMS, MongoDB is horizontally scalable. This reduces the workload as no CPU and memory need to be added to the same server. It results in the reduction of cost expenses related to CPU and the maintenance charges as well. Hence, it can quickly scale the business.
- One of the reasons why MongoDB is popular among the developers is because it supports many platforms inclusive of Windows, macOS, Ubuntu, Debian, Solaris.
- The database added a new feature to its list of attributes called MongoDB Atlas. It is a global cloud database technology that allows to deploy a fully managed MongoDB across AWS, Google Cloud, and Azure with its built-in automation for resource, workload optimization and to reduce the time required to handle the database.
- Application Areas: MongoDB is fit for those businesses where the data’s blueprint is not clearly defined or updated frequently. It’s used in various domains: Internet of Things (IoT), Time Series, businesses using real-time analytics, content management systems, mobile apps, eCommerce, payment processing, personalization, catalog, and gaming.
- Key Customers: Adobe, AstraZeneca, Barclays, BBVA, Bosch, Cisco, CERN, eBay, eHarmony, Elsevier, Expedia, Forbes, Foursquare, Gap, Genentech, HSBC, Jaguar Land Rover, KPMG, MetLife, Morgan Stanley, OTTO, Pearson, Porsche, RBS, Sage, Salesforce, SAP, Sega, Sprinklr, Telefonica, Ticketmaster, Under Armour, Verizon Wireless

- It is an open-source, user-available No-SQL database delivering high-availability.
- Cassandra is a peer-to-peer distributed system that comprises a cluster of nodes in which any node can accept a read or write request (i.e., each node has some role)
- This “masterless” feature of Cassandra allows it to offer high scalability. All the nodes are homogenous, which helps create operational simplicity; when new machines are added, it does not interrupt the other applications. Hence, it is easy to scale up to more extensive database architecture.
- Cassandra supports the replication of data to multiple data centers and keeps multiple copies in various locations.
- The database is designed to have a distributed system to deploy a larger number of nodes across the various data centers.
- Its design enhances read and write processing commands and can handle massive data very quickly.
- It is also good at writing time-based log activities, error logging, and sensor data.
- Cassandra is fault-tolerant; that is, it offers zero-point failures. In case a node fails, it is replaced immediately, causing minimal impact on the production performance. It supports the redundancy of the data.
- It provides data protection by its commit log design feature that ensures that the data is not lost. Along with this, it has data backup and restores features.
- It has introduced Cassandra Query Language (CQL), a simple interface to interact with the database.
- Even though Cassandra is non-ACID compliant, it supports some SQL statements such as DDL, DML, and SELECT statements.
- Cassandra supports Hadoop integration with MapReduce and also with Apache Hive and Apache Pig.
- Application Areas: If you want to work with SQL-like data types on a No-SQL database, Cassandra is a good choice. It is a popular pick in the IoT, fraud detection applications, recommendation engines, product catalogs and playlists, and messaging applications, providing fast real-time insights.

- The schema of the data is not a concern as the data is stored in a flexible document-based structure.
- CouchDB allows to run a single logical database server on any number of servers.
- It uses multiple formats and protocols to store, transfer and process the data.
- The focus of CouchDB is on the web as it uses the HTTP protocol to access the documents. The HTTP-based REST API allows communication with the database easily.
- The structure of HTTP resources and methods such as GET, PUT, DELETE are easy to understand, making the document insertion, updation, retrieval, and deletion relatively easy.
- It allows access to the data by defining the Couch Replication Protocol. Using this can copy, share and synchronize the data between the databases and the machines.
- Likewise, Cassandra, CouchDB also offers distributed scaling with fault-tolerant storage.
- Unlike MongoDB and Cassandra, CouchDB is ACID compliant.
Distributed Storage and Processing Tools
A distributed storage system is an infrastructure that splits data across multiple physical servers and more than one data center. It typically takes the form of a cluster of storage units, with a mechanism for data synchronization and coordination between cluster nodes.
On the other hand, distributed processing refers to various computer systems that use more than one computer (or processor) to run an application. This includes parallel processing in which a single computer uses more than one CPU to execute programs.
The tools that fall under this category are:
Hadoop is an Apache open-source framework. Written in Java, Hadoop is an ecosystem of components that are primarily used to store, process, and analyze big data. The USP of Hadoop is it enables multiple types of analytic workloads to run on the same data, at the same time, and on a massive scale on industry-standard hardware.
Cloudera Distribution Hadoop (CDH) is an open-source Apache Hadoop, offered by Cloudera Inc, a US-based software company. CDH is also a distribution platform for many other Apache products, including Spark, Hive, Impala, Kudu, HBase, and Avro.
The data in Hadoop is stored on inexpensive commodity servers that run as clusters. It allows distributed processing of large datasets across the clusters of computers using simple programming models.
The Hadoop application works in an environment that provides distributed storage and computation across the clusters of computers. It is designed to scale from a single server to thousands of machines, where each offers local computation and storage. Hadoop processes the data in parallel and not on a sequential or serial basis.
- Hadoop Distributed File System (HDFS) for storage of the data. Its distributed file system runs on commodity hardware.
- MapReduce, a parallel programming model for efficient processing of data on large clusters (or nodes) of commodity hardware in a reliable and fault-tolerant manner.
- Hadoop Common is Java libraries and utilities that are required to enable third-party modules to work with Hadoop.
- Hadoop YARN, a framework for resource or job scheduler and cluster resource management

- Hadoop ensures the high availability of the data.
- It allows for faster data processing and also brings flexibility in the processing of the data.
- Hadoop has a replication mechanism. It creates replication of data in the cluster. This also ensures reliability in the data as the data is stored reliably on the cluster machines despite any machine failures.
- Hadoop’s libraries are designed to detect and handle failures at the application layer, and hence, it does not rely on hardware to provide fault-tolerance and high availability.
- Hadoop is highly scalable. We can add more servers (i.e., horizontal scalable) or increase the hardware capacity of clusters (which is vertical scalable) to achieve high computation power. The servers can be added or removed from the cluster dynamically, and Hadoop can operate continually without any interruption.
Spark, a product of Apache Software Foundation, was introduced to speed up the computational computing software process of Hadoop. Databricks is an open and unified data analytics platform for data engineering, data science, machine learning, and analytics.
