The subject of data science has had amazing growth over the last several years, and as a result, the number of positions and responsibilities that are available within the field has also increased. There are instances when the inventive titles of work responsibilities are difficult to interpret, and this leaves us wondering precisely what our area of emphasis ought to be. This article provides an explanation of some of the several subfields that fall under the umbrella of data science, as well as the technical abilities or knowledge that are often required to be successful in the professions. Here are some of the more frequent ones that you may have encountered throughout your travels. statistician of data The majority of individuals who work with data are referred to as data scientists, mostly due to the fact that the term encompasses such a wide range of responsibilities. There have also been instances when terminology like “citizen data scientist” have gained popularity. This term refers to those who are neither educated or credentialed in the area of data science but have taught themselves many of the applications within the field. The definition of a true data scientist is someone who is capable of mastering multiple skills, beginning with working with raw data and continuing through the use of statistical methods through data programming tools such as Python or R, and who is able to present all of these insights to a wider business in a straightforward manner. Machine learning, big data technologies, predictive statistics, recommender systems, and distributed computing are often considered to be the primary tasks (computers on numerous networks or disparate data). Large corporations such as Google and Facebook are well-known for employing a large number of data scientists to work on the massive amounts of complicated algorithms that they use to run their operations. analysts of data Using programming languages and tools such as R, Python, SQL, and Visual Basic, a data analyst will take the work that was completed by a data scientist and do more in-depth analysis on it (excel). In contrast to older positions, which may have merely reported the findings as management information, the primary objective of a data analyst is to determine the reasons behind the occurrence of a certain measurement. For instance, if a retail company sells ten things on a Monday and twenty products on the Monday before, a data analyst will seek to determine the underlying reason of the discrepancy between the two days and then relay that information to the appropriate teams. Reporting technologies like Qlik, Tableau, and Sisense, to mention a few, are often used by data analysts in order to present their results to the audience. data engineer A data engineer is the person who will be in charge of creating the infrastructure that the data scientists and analysts will be utilizing. The quality of the models that are constructed by these roles is directly proportional to the quality of the data that is used to feed them. A data engineer is responsible for ensuring that this governance is applied through the use of big data technologies, etl processes, and complex queries that ultimately lead to a “single source of truth.” Not only do data engineers often lack knowledge in machine learning and statistical methodologies, but they also concentrate primarily on the design and architecture of the datasets they work with. One excellent illustration of this is the situation in which firms have several different data sources. A website, a back-office system, a finance system, a telephony system, Google Analytics, Facebook Ads, a marketing platform, a human resources system, payment systems, an email exchange, live chat or chat bots, and maybe even an app are all likely to be there. The data engineer will strive to consolidate all of these into a single data warehouse that can be used by everyone else, and they will also seek to build confidence in the work that the other members of the team are engaged in. the developer of data As of right moment, this position is quite desirable and may be considered the most sought after. To some extent, a data developer may be thought of as a hybrid between a data scientist and a data engineer. In contrast to a data scientist, who is primarily concerned with the development of statistical models and algorithms, a data developer will work toward the creation of products that transform these into comprehensive commercial solutions. The data developer will progressively collect data from a variety of models, get some insights from teams and analysts, and create solutions that are capable of deploying the work that they are doing in a step-by-step manner. With this in mind, the ultimate goal of the developer is to produce business value solutions by using data, despite the fact that they are knowledgeable about engineering, machine learning, and architecture. Despite the fact that the specific context of this varies from company to company, it is a position in which algorithms and machine learning may truly be applied into operations that are associated with business as usual. A manager of data Data managers are often seasoned data professionals who have a more strategic perspective on how data may be utilized as a business asset for commercial purpose. This is because data managers are responsible for managing data. In order to guide the team and develop a data culture both inside and outside of the organization, they will have an understanding of all the many responsibilities that we have just discussed, but they will not necessary be a master of any of them. Due to the fact that data science initiatives are only valuable if they have a practical or commercial goal that gives a benefit to the actual world, a job such as this is very crucial. Take, for instance, the scenario in which a member of the marketing team requested that the data scientist devote some of their time to developing an algorithm that can determine the nation from which the next consumer would originate. It is possible that it is a great and enjoyable little tool, but it does not serve any practical use for the company. A data manager is responsible for ensuring that time is used efficiently and that any initiatives are linked with the revenue of the company or the experience of the customers. Aside from that, what exactly are big data and machine learning? All of these positions are included in the realm of machine learning and big data operations. These are both very wide concepts that are subcategories of artificial intelligence; nonetheless, they both entail the use of computers to gather data and automate operations without the need for manual interaction from humans. Consequently, they are often used as buzzwords within the majority of data positions due to the fact that they are so inclusive and relevant to practically any project. As the area of data continues to evolve, a variety of different job titles are emerging, such as data modeller, data architect, data evangelist, data artist, and even a few data ninjas! These are just some of the roles that are emerging. All of them, however, are connected to the basic activities that were discussed in this article, and these are the areas that it is essential to have a working understanding of in order to advance in the field.
