Want to learn new data skills while home? We've rounded up five of the best data certificates that you can earn without leaving the house.
Data Science has rapidly expanded in the last two years, with Machine Learning Engineers, Big Data Engineers, and Data Scientists ranking amongst the top emerging positions on LinkedIn.
Data science is “inherently multidisciplinary,” as John Foreman, MailChimp’s Vice President of Product Management, once said, explaining why Data Scientists were “kind of like the new Renaissance folks.” The field draws on elements of computer science, statistics, and mathematics; a unique blend that is not typically covered in university degree programs.
This is one of the reasons why data science training, courses, and diploma programs are increasing in popularity, helping professionals master the skills they need to meet the demands of this rising field.
And when it comes to transitioning into a career in data, one group of professionals may be in better position than most: Developers.
Here are three reasons Web Developers make great Data Scientists.
They’re Got a Background in Data Curation
Data Science typically covers two broad areas: data analytics and data curation. Analytics deals with analyzing and extracting relevant insights and knowledge from data. This is the activity that people most often associate with data scientists: crunching numbers and producing actionable insights and predictive models. But there is another side to data science: figuring out how to collect, manage, preserve, document, transform, alter, and access the data effectively and efficiently in order for analytics to be possible. In academia, these activities are often referred to as data curation.
Data curation involves the capturing, modeling, management, documentation, storage, transformation, and retrieval of data. In the professional world, titles for a specialist in data curation include Data Engineer, Data Developer, Business Intelligence Developer, Big Data Specialist, or sometimes just Data Scientist.
These specialists would need to have a strong understanding of the following aspects:
- The relational model and its various implementations (SQL Server, Oracle Database, MySQL, etc.)
- NoSQL databases including:
- The Document Store model and NoSql databases like MongoDB
- Wide column databases like Cassandra
- Key-value stores like Redis
- The MapReduce programming model and its implementation in Apache Hadoop.
- Cloud computing platforms like Amazon Web Services and Microsoft Azure
While the specific technologies are constantly changing and fluctuating in popularity and relevance, the core concepts and ideas remain more constant.
Given these requirements, professionals with training in data structures and computer science are in a great position to lead data curation activities on data science teams. Those with a computer science background, in particular, are well suited for this kind of work, as data structures, schemas, or entity-relationship models are all cornerstones of a computer science education.
They’re Familiar With Programming Languages
Successful Data Scientists have to have a knowledge of programming languages, including R, Python (53% of data scientists “speak” R and/or Python), SQL, and Java, among others.
This gives developers an obvious advantage over other professionals looking to make the switch into data – even if they’re not familiar with these languages. Put simply, a good developer or programmer will learn languages as the need arises, which means they are constantly learning new tools, languages, frameworks, and theories.
This emphasis on continuous learning is ideal for the still nascent data science field, which is growing and changing rapidly. After all, when starting a career in data science (and data analytics), one of the first steps is often learning how to build a predictive model using machine learning. Models have to be trained, tested, tuned, validated, and deployed, and Data Scientists should understand each step in this process.
They Know How to Program
The challenge for Data Scientists in the future will not be in building the aforementioned predictive models, but in integrating these kinds of data toolkits into an organization’s production stack. And, apart from an affinity for numbers, that takes computer science knowledge and programming experience over anything else.
As Josh Wills, Slack’s Director of Data Engagement, once said, a Data Scientist is a “person who is better at statistics than any software engineer, and better at software engineering than any statistician.”
In other words, advantage developers.
