Data vs Data Science

Business Analyst

Business Analyst

The role of business analysts is slightly different from other data science jobs. While they do have a good understanding of how data-oriented technologies work and how to handle large volumes of data, they also separate the high-value data from the low-value data. In other words, they identify how Big Data can be linked to actionable business insights for business growth.

Although many of their job tasks are similar to that of data analysts, business analysts are experts in the domain they work in. They try to narrow the gap between business and IT. Business analysts provide solutions that are often technology-based to enhance business processes, such as distribution or productivity.

Organizations need these “information conduits” for a plethora of things such as gap analysis, requirements gathering, knowledge transfer to developers, defining scope using optimal solutions, test preparation, and software documentation.

Roles & Responsibilities:

  1. Business analysts identify business needs, crystallizing the data for easy understanding, manipulation, and analysis via clear and precise requirements documentation, process models, and wireframes. They identify key gaps, challenges, and potential impacts of a solution or strategy.
  2. In a day, a business analyst could be doing anything from defining a business case or eliciting information from top management to validating solutions or conducting quality testing. Business analysts need to be effective communicators and active listeners, resilient and incisive, to translate tech-speak or statistical analysis into business intelligence.
  3. They use predictive, prescriptive, and descriptive analyses to transform complex data into easily understood actionable insights for the users. A change manager, a process analyst, and a data analyst could be doing business analysis tasks in everyday work.

Skills Required:

  1. Apart from a degree in business administration in the field of your choice, healthcare or finance, aspiring business analysts need to have knowledge of data visualization tools such as Tableau and requisite IT know-how, including database management and programming.
  2. You could also major in computer science with additional statistics, organizational behavior, and quality management courses. Or you could get professional certifications such as the Certified Business Analysis Professional (CBAP®) or PMI Professional in Business Analysis (PBA). Many universities offer degrees in business intelligence, business analytics, and analytics. Check out the courses in the U.S/India.

The career path would be Data Engineer → Senior Data Engineer → BI Architect → Data Architect

Data Analyst

Data Analyst

Languages like R, Python, and SQL are part of the data analyst’s basic knowledge. Much like the data scientist role, a broad skill set is also required for the data analyst role, which combines technical and analytical knowledge with ingenuity.

Roles & Responsibilities:

  1. Data analysts are responsible for various tasks, including visualization, munging, and processing massive amounts of data.
  2. They also must perform queries on the databases from time to time, looking into the key metrics of a business. They oversee data that is scraped, assuring the quality and managing it. They must interpret data and effectively communicate the findings.
  3. Designing and deploying algorithms, culling information and recognizing risk, extrapolating data using advanced computer modeling, triaging code problems, and pruning data are all in a day’s work for a data analyst.
  4. They also do presentations and work with stakeholders or non-technical stakeholders. It will be your responsibility to promote data literacy and emphasize the importance of your findings. The quality of the analysis is always paramount, but you will be evaluated mostly on the impact you are driving. This means that you always must ask, “So what?” to every insight your analysis reveals and, above all, make sure to communicate clearly what your analysis means to the end-user and what are your recommended actions.
  5. They also do AB testing and significance testing, where they analyze the model’s output and decide if there has been enough impact to continue the current model process, enhance it with new features or metrics and set up experiments. The goal of this role is to save the company money and time and make the business more competitive.

Unlike data scientists, data analysts are more generalists. Udacity calls them junior data scientists. They play a gamut of roles, from acquiring massive amounts of data to processing and summarizing it. This role can have a lot of freedom in the ways that you drive impact. Any trend or insight you identify and convince decision-makers to act upon is a win.

The potential downside of this freedom is that you will often not have a single clearly defined question to pursue, which can cause a lack of focus or frustration because you are not sure what to work on. Developing a sense of priorities and the ability to identify high-impact projects will be key skills.

The word “Analyst” tends to have a more junior connotation, and hence many companies (especially in the technology sector) instead use “Data Scientist”. My advice would be to not pay much attention to the word used and instead focus on the job description, team, company, and, of course, the potential salary

Skills Required:

  1. Data analysts are expected to know R, SAS, Python, HTML, SQL, C++, and Javascript. certification in these can easily give a boost to your job applications. You should also have good problem-solving qualities.
  2. They need to be more than a little familiar with data retrieval and storing systems, data visualization, and data warehousing using ETL tools, Hadoop-based analytics, and business intelligence concepts.
  3. Product sense, cross-discipline collaboration, AB testing, metric definition, data visualization, and stakeholder communication.
  4. These persistent and passionate data miners usually have strong math, statistics, machine learning, and programming background.

SQL, R, SAS, and Python are some sought-after data analysis technologies. So, certification in these can easily give a boost to your job applications. You should also have good problem-solving qualities.

Machine Learning Engineer

Machine learning engineers are in high demand today. However, the job profile comes with its challenges. Apart from having in-depth knowledge of some of the most powerful technologies such as SQL, REST APIs, etc., machine learning engineers are also expected to perform A/B testing, build data pipelines, and implement common machine learning algorithms such as classification, clustering, etc. This is a highly desired role and can be behind some of the most user-facing applications the internet has to offer today, such as recommendations systems or Spotify’s Discover Weekly playlist.

Roles & Responsibilities:

  1. To address business challenges, machine learning engineers must design and implement machine learning applications/algorithms such as clustering, anomaly detection, classification, or prediction.
  2. ML engineers build data pipelines, benchmark infrastructure, and do A/B testing.
  3. They work collaboratively with product and development teams to improve data quality via tooling, optimization, and testing. ML engineers must monitor the performance and ensure the organization’s reliability of machine learning systems.

Skills Required:

  1. Engineers should focus on Python, Java, Scala, C++, and Javascript.
  2. To become a machine learning engineer, you need to know to build highly scalable distributed systems, be sure of the machine learning concepts, play around with big datasets, and work in teams that focus on personalization.
  3. ML engineers are data- and metric-driven and have a strong foundation in mathematics and statistics. They are expected to have experience in Elasticsearch, SQL, Amazon Web Service, and REST APIs.
  4. In this role, you will sit between the data science and engineering realms: you need to have a great understanding of statistical and machine learning models and be able to implement a scalable backend solution to ship your model into production.
  5. This role is much more technical than the product data analyst and can be even more technical than the modeling analyst. Like the modeling analyst, this role is usually situated within a team of other technical roles such as other MLEs and data scientists. The main performance indicator will be the quality of your backend work and the ML models you ship.
  6. Machine learning models, statistics, back end engineering, the above three job categories likely cover most “traditional” data science jobs, but I think there is a new category of hybrid data scientist positions that are being created in response to the demand for data scientists that have data engineering and data visualization skills.
  7. As always, great communication skills are vital to interpreting complex ML concepts to non-experts.

How to Become a Machine Learning Engineer?

Firstly, you must have a sound knowledge of some of the technologies like Java, Python, JS, etc. Secondly, you should have a strong grasp of statistics and mathematics. Once you have mastered both, it is a lot easier to crack a job interview.
