There are thousands of Big Data tools out there. All of them promising to save you time, money and help you uncover never-before-seen business insights. And while all that may be true, navigating this world of possible tools can be tricky when there are so many options.
Which one is right for your skill set?
Which one is right for your project?
To save you some time and help you pick the right tool the first time, we’ve compiled a list of a few of our favorite data tools in the areas of extraction, storage, cleaning, mining, visualizing, analyzing and integrating.
Data Storage and Management
If you’re going to be working with Big Data, you need to be thinking about how you store it. Part of how Big Data got the distinction as “Big” is that it became too much for traditional systems to handle. A good data storage provider should offer you an infrastructure on which to run all your other analytics tools as well as a place to store and query your data.
The name Hadoop has become synonymous with big data. It’s an open-source software framework for distributed storage of very large datasets on computer clusters. All that means you can scale your data up and down without having to worry about hardware failures. Hadoop provides massive amounts of storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.
Hadoop is not for the data beginner. To truly harness its power, you really need to know Java. It might be a commitment, but Hadoop is certainly worth the effort - since tons of other companies and technologies run off of it or integrate with it.
Get started: Cloudera has some great Hadoop training courses.
Speaking of which, Cloudera is essentially a brand name for Hadoop with some extra services stuck on. They can help your business build an enterprise data hub, to allow people in your organization better access to the data you are storing.
While it does have an open source element, Cloudera is mostly and enterprise solution to help businesses manage their Hadoop ecosystem. Essentially, they do a lot of the hard work of administering Hadoop for you. They will also deliver a certain amount of data security, which is highly important if you’re storing any sensitive or personal data.
Get started: Cloudera has a long list of webinars covering all different types of use.
MongoDB is the modern, start-up approach to databases. Think of them as an alternative to relational databases. It’s good for managing data that changes frequently or data that is unstructured or semi-structured.
Common use cases include storing data for mobile apps, product catalogs, real-time personalization, content management and applications delivering a single view across multiple systems. Again, MongoDB is not for the data newbie. As with any database, you do need to know how to query it using a programming language.
Getting started: MongoDB has their own “University” where you can learn to use their services and even get a certification.
Talend is another great open source company that offers a number of data products. Here we’re focusing on their Master Data Management (MDM) offering, which combines real-time data, applications, and process integration with embedded data quality and stewardship.
Because it’s open source, Talend is completely free making it a good option no matter what stage of business you are in. And it saves you having to build and maintain your own data management system - which is a tremendously complex and difficult task.
Get started: Talend have a good (if slightly 90’s looking) set of tutorials for getting started
Start from the beginning
If you’re completely new to Big Data, databases might not be the best place to start. They are relatively complex and do require a certain amount of coding knowledge to operate (unlike many of the other tools mentioned below).
However, if you really want to work in or with Big Data, knowing the basics of databases and being able to talk intelligently about them is a must. This General Assembly Class is a great place to start. You’ll get a comprehensive overview of the technologies powering big data, including the history of databases and storage, the difference between relational and document databases, the challenges of big data and the tools it necessitates, as well as an introduction to Hadoop.
Before you can really mine your data for insights you need to clean it up. Even though it’s always good practice to create a clean, well-structured data set, sometimes it’s not always possible. Data sets can come in all shapes and sizes (some good, some not so good!), especially when you’re getting it from the web. The companies below will help you refine and reshape the data into a useable data set.
OpenRefine (formerly GoogleRefine) is an open source tool that is dedicated to cleaning messy data. You can explore huge data sets easily and quickly even if the data is a little unstructured.
As far as data softwares go, OpenRefine is pretty user-friendly. Though, a good knowledge of data cleaning principles certainly helps. The nice thing about OpenRefine is that it has a huge community with lots of contributors meaning that the software is constantly getting better and better. And you can ask the (very helpful and patient) community questions if you get stuck. You can check out theirGithub repository where you can also find the OpenRefine wiki.
DataCleaner recognises that data manipulation is a long and drawn out task. Data visualization tools can only read nicely structured, “clean” data sets. DataCleaner does the hard work for you and transforms messy semi-structured data sets into clean readable data sets that all of the visualization companies can read.
DataCleaner also offers data warehousing and data management services. The company offers a 30-day free trial and then after that a monthly subscription fee. You can find out more about their plans here.
Getting started: DataCleaner has a thorough set of documentation and videos. For their commercial plans, they also offer in-person or webinar training
Not to be confused with data extraction (covered later), data mining is the process of discovering insights within a database as opposed to extracting data from web pages into databases. The aim of data mining is to make predictions and decisions on the data you have at hand.
With a hefty client list that includes PayPal, Deloitte, eBay and Cisco, RapidMiner is a fantastic tool for predictive analysis. It’s powerful, easy to use and has a great open source community behind it. You can even integrate your own specialized algorithms into RapidMiner through their APIs.

If you’re after a specific type of data mining there are a bunch of startups which specialize in helping businesses answer tough questions with data. If you’re worried about user churn, we recommend FramedData, a startup which analyzes your analytics and tell you which customers are about to abandon your product.
It’s a fully managed solution which means you don’t need to do anything but sit back and wait for insights.
Get started: if you’re interested the best thing to do is request a demo
If you’re stuck on a data mining problem or want to try solving the world’s toughest problems, check outKaggle. Kaggle is the world's largest data science community. Companies and researchers post their data and statisticians and data miners from all over the world compete to produce the best models.
While data mining is all about sifting through your data in search of previously unrecognized patterns, data analysis is about breaking that data down and assessing the impact of those patterns overtime. Analytics is about asking specific questions and finding the answers in data. You can even ask questions about what will happen in the future!
Qubole simplifies, speeds and scales big data analytics workloads against data stored on AWS, Google, or Azure clouds. They take the hassle out of infrastructure wrangling. Once the IT policies are in place, any number of data analysts can be set free to collaboratively “click to query” with the power of Hive, Spark, Presto and many others in a growing list of data processing engines.

Data visualization companies will make your data come to life. Part of the challenge for any data scientist is conveying the insights from that data to the rest of your company. For most of your colleagues, MySQL databases and spreadsheets aren’t going to cut it. Visualizations are a bright and easy way to convey complex data insights. And the best part is that most of them require no coding whatsoever!
Tableau is a data visualization tool with a primary focus on business intelligence. You can create maps, bar charts, scatter plots and more without the need for programming. They recently released a web connector that allows you to connect to a database or API thus giving you the ability to get live data in a visualisation.
Tableau has five products available with varying degrees of support and functionality. If you’re new to vizzing (as they call it) we recommend Tableau Public, the free version of their visualization tooling. Exploring that tool should give you an idea of which of the other Tableau products you’d rather pay for.
Get started: Tableau has a lot of functionality, so definitely check out their tutorialsbefore diving in.
Silk is a much simpler data visualization and analytical tool than Tableau. It allows you to bring your data to life by building interactive maps and charts with just a few clicks of the mouse. Silk also allows you to collaborate on a visualisation with as many people as you want.
Like many of the visualization companies on this list, Silk doesn’t require you to be an expert programmer. If you’re new to visualizing data, this is the place to start because their latest feature attempts to visualize your data automatically without you having to do a thing.
Get started: Silk has an extremely large collection of tutorials on their website.
CartoDB is a data visualization tool that specialises in making maps. They make it easy for anyone you to visualize location data - without the need for any coding. CartoDB can manage a myriad of data files and types, they even have sample datasets that you can play around with while you’re getting the hang of it.
If you have location data, CartoDB is definitely worth a look. It may not be the easiest system to use, but once you get the hang of it, it is incredibly powerful. They offer an enterprise package which allows for collaboration on projects as well as controlled access.
Getting started: They have an extensive library of documentation to help you become a mapping expert.
Chartio allows you to combine data sources and execute queries in-browser. You can create powerful dashboards in just a few clicks.

There will be times in your data career when a tool simply won’t cut it. While todays tools are becoming more powerful and easier to use, sometimes it is just better to code it yourself. Even if you’re not a programmer, understanding the basics of how these languages work will give you a better understanding of how many of these tools function and how best to use them.
R is a language for statistical computing and graphics. If the data mining and statistical software listed above doesn’t quite do what you want it to, learning R is the way forward. In fact, if you’re planning on being a data scientist, knowing R is a requirement.
It can run on Linux, Windows and MacOS and you can download R at this page. There is a huge community of statisticians using R nowadays and its popularity is always growing.
Getting started: Once downloaded, you can check out the documentation
Another language that is gaining popularity in the data community is Python. Created in the 1980s and named from Monty Python’s Flying Circus, it has consistently ranked in the top ten most popular programming languages in the world. Many journalists use Python to write custom scrapers if data collection tools fail to get the data that they need.
People like it because of the similarities with the English language. It uses words such as ‘if’ and ‘in’ meaning you can read a script very easily. It offers a wide range of libraries designed for different types of tasks.
Getting started: Check out the homepage to learn more about Python
RegEx or Regular Expressions are a set of characters that can manipulate and change data. It’s used mainly for pattern matching with strings, or string matching. At Import.io, you can use RegEx while extracting data to delete parts of a string or keep particular parts of a string.
It is an incredibly useful tool to use when doing data extraction as you can get exactly what you want when you extract data meaning you don’t need to rely on those data manipulation companies mentioned above!
Getting started: There are many cool tutorials for RegEx online
XPath is a query language used for selecting certain nodes from an XML document. Whereas RegEx manipulates and changes the data makeup, XPath will extract the raw data ready for RegEx.
XPath is most commonly used in data extraction. Import.io actually automatically creates XPaths everytime you click on a piece of data - you just don’t see them! It is also possible to insert your own XPath to get data from drop down menus and data that is in tabs on a webpage. Put simply, an XPath is a path, a set of directions to a certain part of the HTML of a webpage.
Getting started: The best XPath tutorial is the w3schools tutorial
Before you can store, analyze or visualize your data, you’ve got to have some. Data extraction is all about taking something that is unstructured, like a webpage, and turning it into a structured table. Once you’ve got it structured, you can manipulate it in all sorts of ways, using the tools we’ve covered, to find insights.
Import.io is the number one tool for data extraction. Using a really simple point and click UI, we take a webpage and transform it into an easy to use spreadsheet that you can then analyze, visualize and use to make data-driven decisions.
As well as hosting a free to use tool, Import.io is also a data provider. We make bespoke data sets tailored for each client. This data can then be refreshed on a schedule meaning that your business will get the most up to date data all of the time.
Getting started: Check out the knowledge base to learn exactly how to use the tool or contact the data experts to get a tailored data solution for your business.
