And why is it important? Watch this video for an introduction to the field, or keep reading!<\/p>\n<style type=\"text\/css\">.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }<\/style>\n<div class=\"embed-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/yZvFH7B6gKI\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<p>In its simplest form, data analytics is the process of drawing meaning from disordered information. By systematically exploring data for patterns and relationships, data analysts seek to find and communicate useful insights using those data. But what counts as data? Well, pretty much anything you can imagine. Often, data are numerical (quantitative data). But sounds, images, words, or anything else that can be interpreted in some way can also be classed as data (qualitative data).<\/p>\n<p>An analyst\u2019s job begins with what\u2019s known as \u2018raw data.\u2019 Raw data are disordered and\u2014without context\u2014essentially meaningless. We can only obtain useful information from them once we have brought order to chaos. As such, collecting, cleaning, and organizing data are all parts of the data analytics process.<\/p>\n<p>What\u2019s more, effective data analytics incorporates many techniques to help the process along. These include statistics, programming, visualization, and more. Luckily, to streamline the process, many of these techniques have been automated. Some are even developing as fields in their own right. However, a good data analyst will have at least some knowledge of them all.<\/p>\n<h3 id=\"why-does-data-analytics-matter\">Why does data analytics matter?<\/h3>\n<p>There are two simple reasons why data analytics matters. Firstly, it\u2019s useful for decision-making. Secondly, it\u2019s evidence-based. Combine these two attributes, and data analytics becomes a potent tool. Basing decisions on empirical information (rather than relying on opinion or \u2018gut feel\u2019) is a much more scientific way of approaching problems. While this does not mean data analytics is always 100% accurate, it\u2019s by far the best tool we have for predicting future trends and drawing conclusions about past events.<\/p>\n<p>Data analytics also has a wide range of applications across society. Online, you\u2019ll often find data analytics touted as a tool for business intelligence, e.g. predicting future sales or informing product development and marketing spend.<\/p>\n<p><img decoding=\"async\" title=\"A data analyst looking at some graphs on a tablet\" src=\"\/en\/wp-content\/uploads\/old-blog-uploads\/data-analyst-role.jpg\" alt=\"A data analyst looking at some graphs on a tablet\" \/><\/p>\n<h2 id=\"what-does-a-data-analyst-actually-do\">2. What does a data analyst do?<\/h2>\n<p>Now we know <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/what-is-data-analytics\/\">what data analytics is<\/a>, let\u2019s take a look at what the role of the data analyst actually entails.<\/p>\n<p>As a data analyst, it\u2019s your responsibility to turn raw data into meaningful insights. Following the data analysis process (which we\u2019ll cover in the next section), you\u2019ll solve specific problems or answer certain questions based on data and the insights it provides.<\/p>\n<p>You\u2019ll then take these insights and share them with key stakeholders and decision makers, who can take action or plan for the future accordingly. At the same time, data analysts may be responsible for overseeing the overall processes for collecting and storing data, as well as setting guidelines for <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/what-is-data-quality\/\">data quality<\/a>.<\/p>\n<p>A great way to gauge what a data analyst actually does on a day-to-day basis is to look at the tasks and responsibilities that are typically listed in <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/data-analyst-job-descriptions\/\">data analyst job descriptions<\/a>. Based on actual job descriptions posted on <a href=\"https:\/\/www.indeed.com\/q-Data-Analyst-jobs.html?vjk=506be1482a84cf0e\" rel=\"noopener\">indeed.com<\/a>, here\u2019s what you can expect to do as a data analyst:<\/p>\n<ul>\n<li>Develop and implement databases and data collection systems<\/li>\n<li>Work closely with management to identify critical metrics and KPIs, and to prioritize business needs<\/li>\n<li>Collect data from primary and \/ or secondary data sources<\/li>\n<li>Filter and clean data<\/li>\n<li>Identify, analyze, and interpret trends and patterns in complex data sets<\/li>\n<li>Visualize and present findings to key stakeholders<\/li>\n<li>Build and customize reports<\/li>\n<li>Develop and maintain dashboards<\/li>\n<li>Create and maintain documentation regarding data models, measures, and infrastructure as they are developed<\/li>\n<\/ul>\n<p>So far, we\u2019ve taken a rather high-level look at the work of a data analyst. Next, we&#8217;ll look at the difference in the job titles of\u00a0<strong>data analyst<\/strong> and\u00a0<strong>data scientist<\/strong>.<\/p>\n<h2 id=\"data-analyst-vs-data-scientist\">3. Data analyst vs. data scientist: What&#8217;s the difference?<\/h2>\n<p>So, you may have already done a bit of research into the role of the data analyst and come across some content which talks about data science. Despite the fact that these two terms are often used interchangeably, they are in fact two separate career paths, serving different purposes\u2014and requiring a different skillset.<\/p>\n<p>As we&#8217;ve already covered, data analysts use a company&#8217;s data and interpret it for those in charge of making business decisions. Their work is focused on answering questions and developing solutions by looking into data patterns and turning those into dashboards and visualizations for broader use.<\/p>\n<p>In turn, a data scientist will work deeper within the data, identifying patterns using data mining and machine learning. They will set up experiments, then produce models and tests in order to prove or disprove their findings. Then, based on their findings, they\u2019ll offer solutions as to how a company should act going forward.<\/p>\n<p><strong>In short:<\/strong> data analysts analyze the past, while data scientists are more concerned with the future. To look into this topic in more detail, check out this article: <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/difference-between-data-scientist-and-data-analyst\/#what-are-the-main-differences-between-data-analysts-and-data-scientists\">What&#8217;s The Difference Between A Data Scientist And A Data Analyst?<\/a><\/p>\n<h2 id=\"types-of-data-analysts\">4. What types of data analysts are there?<\/h2>\n<p>As you might have been able to glean so far, the practice of data analysis has an important function with applications across many industries.<\/p>\n<p>However, data analytics goes far beyond simply boosting a company\u2019s bottom line. It\u2019s also used in health settings to <a href=\"https:\/\/healthinformatics.uic.edu\/blog\/how-health-care-analytics-improves-patient-care\/\" rel=\"noopener\">improve patient care<\/a>. It\u2019s currently <a href=\"https:\/\/www.futurefarming.com\/Tools-data\/Articles\/2019\/7\/4-ways-big-data-analytics-are-transforming-agriculture-450440E\/\" rel=\"noopener\">being applied in agriculture<\/a> to transform the way we feed the world. It\u2019s even used by governments to tackle <a href=\"https:\/\/www.dhs.gov\/science-and-technology\/news\/2020\/03\/18\/snapshot-combatting-human-trafficking-analytics\" rel=\"noopener\">issues like human trafficking<\/a>. So if you want to help improve the world\u2014as well as business\u2014a career in data analytics might be for you!<\/p>\n<p>With regards to types of data analysts and job titles, here are some of the common titles you may see on job advertisements:<\/p>\n<ul>\n<li><a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/how-to-become-a-business-analyst\/\">Business analyst<\/a><\/li>\n<li>Business intelligence analyst<\/li>\n<li><a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/business-systems-analyst\/\">Business systems analyst<\/a><\/li>\n<li><a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/what-is-a-healthcare-data-analyst\/\">Medical and healthcare analyst<\/a><\/li>\n<li>Market research analyst<\/li>\n<li><a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/operations-analyst\/\">Operations analyst<\/a><\/li>\n<li>Intelligence analyst<\/li>\n<\/ul>\n<p>Now let\u2019s zoom in on some of the more specific tasks associated with the data analysis process.<\/p>\n<h2 id=\"what-tasks-and-processes-does-a-data-analyst-follow\">5. What tasks and processes does a data analyst follow?<\/h2>\n<p>As a data analyst, your job is to carry out each step of <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/the-data-analysis-process-step-by-step\/\">the data analytics process<\/a> to identify and solve a problem.<\/p>\n<p>As your career progresses, you may choose to specialize in a particular area, such as data visualization or data engineering. As a beginner, though, it\u2019s important to learn the process as a whole.<\/p>\n<p>So, what are the key tasks and processes that a data analyst should expect to follow? Here&#8217;s a brief video overview, from my colleague Will:<\/p>\n<style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }<\/style>\n<div class=\"embed-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/lgCNTuLBMK4\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<p>Although it\u2019s not as straightforward as following one task directly after another (you may find yourself repeating steps, going back on yourself, and so on) the main tasks include:<\/p>\n<p><img decoding=\"async\" title=\"The five steps in the data analysis process: Define the question, gather your data, clean the data, analyze the data, and visualize and share your findings.\" src=\"\/en\/wp-content\/uploads\/old-blog-uploads\/the-data-analysis-process-3.jpg\" alt=\"The five steps in the data analysis process: Define the question, gather your data, clean the data, analyze the data, and visualize and share your findings.\" \/><\/p>\n<ul>\n<li>Defining a question<\/li>\n<li>Collecting data<\/li>\n<li>Data cleaning<\/li>\n<li>Conducting an analysis<\/li>\n<li>Communicating your results<\/li>\n<\/ul>\n<h3 id=\"defining-a-question\">Defining a question<\/h3>\n<p>First up, you need to define your objective. In some ways, this is the hardest part of the process. This is because what seems like an obvious problem may not always get to the core of an issue.<\/p>\n<p>For example, let\u2019s say you work for a company that wants to boost its revenue. The senior management is set on doing this by launching a suite of new products. As a result, you spend lots of time and resources analyzing what products to create, which market to launch them in, and so on.<\/p>\n<p>However, with a bit more probing upfront, you might discover that there\u2019s nothing wrong with the company\u2019s existing products: it\u2019s simply that the sales process is poor, resulting in low customer satisfaction and less repeat business. With this insight, you might find that investing in sales training will boost revenue at a much lower cost.<\/p>\n<p>While this is just a hypothetical case, it illustrates the importance of probing an issue from multiple angles before investing too much time in it. It also means not being afraid to speak truth to power (in this case, telling managers that their new product idea is wrong). Defining the question you want to answer involves obtaining a deep understanding of the needs and demands of the business, keeping track of metrics, KPIs, and so on. You\u2019ll usually carry out some initial analyses at this stage, too.<\/p>\n<h3 id=\"collecting-data\">Collecting data<\/h3>\n<p>Once you\u2019ve identified the question, your next task is to figure out which data are best-suited to help you solve it. This can be quantitative data (such as marketing figures) or qualitative data (such as customer reviews). More specifically, data types can be divided into three categories: first-party data (collected directly by you or your organization), second-party data (the first-party data of another organization), and third-party data (which is aggregated from numerous sources by a third-party).<\/p>\n<p>If you don\u2019t already have access to these data, you\u2019ll have to devise a strategy for collecting them. This might include carrying out surveys, social media monitoring, website analytics, online tracking, and so on. However you collect it, once you have the data at your fingertips, you\u2019re ready to clean it.<\/p>\n<h3 id=\"data-cleaning\">Data cleaning<\/h3>\n<p>Freshly collected data will usually be in a raw format. This means that it hasn\u2019t yet been organized, checked for errors, and so on. To get it into a state that\u2019s suitable for analysis, the data need cleaning. This involves a variety of tools and techniques (such as custom algorithms, generic software, and exploratory analyses) to get it into a more suitable state.<\/p>\n<p>Data cleaning tasks include removing errors, duplicates, and outliers, eradicating unwanted data (i.e. those that don\u2019t serve your analysis), structuring the data in a more useful way, filling in gaps, and so on. When this is done, you\u2019ll validate the data. This involves checking that it meets your requirements. Often, you\u2019ll find it doesn\u2019t, which means you\u2019ll have to go back a step.<\/p>\n<p>For this reason, data cleaning is considered an iterative process. The combined process of collecting and cleaning data is sometimes referred to as <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/data-wrangling\/\">data wrangling<\/a>. You can <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/what-is-data-cleaning\/\">learn more about data cleaning in this guide<\/a>.<\/p>\n<h3 id=\"conducting-an-analysis\">Conducting an analysis<\/h3>\n<p>Once your dataset is clean and tidy, you are good to analyze! There are a great many <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/different-types-of-data-analysis\/\">types of data analysis<\/a>, and part of the challenge is identifying which approach is best-suited to the task at hand. To keep things simple, we\u2019ll offer a quick overview of the four main categories of data analytics.<\/p>\n<p><img decoding=\"async\" title=\"The four main types of data analysis: Descriptive, diagnostic, predictive, and prescriptive.\" src=\"\/en\/wp-content\/uploads\/old-blog-uploads\/the-four-main-types-of-data-analysis-2.jpg\" alt=\"The four main types of data analysis: Descriptive, diagnostic, predictive, and prescriptive.\" \/><\/p>\n<p>The first is descriptive analytics. This involves summarizing (or describing) the features of a dataset to better understand it. It isn\u2019t usually used to draw firm conclusions, but it\u2019s a useful first step for deciding how to investigate the data further.<\/p>\n<p>Next, diagnostic analytics focuses on understanding why something has happened (e.g. by exploring correlations between values in a dataset). This helps identify problems and is often used in the first stage of data analytics, i.e. defining the question.<\/p>\n<p>Finally, we have predictive analysis (which helps to identify trends based on past data) and prescriptive analytics (which helps decide on a future course of action). The latter is sometimes carried out using machine learning techniques.<\/p>\n<h3 id=\"communicating-your-results\">Communicating your results<\/h3>\n<p>Once you\u2019ve carried out an analysis and drawn some insights, the final step is to communicate these to those who commissioned them in the first place. This usually involves <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/what-is-data-visualization\/\">visualizing your data<\/a> in some way\u2014creating graphs and charts, for example.<\/p>\n<p>It may also involve creating interactive dashboards, documents, reports, or presentations. It\u2019s easy to overlook the artistry of this step, but it\u2019s very important to get it right. Not only must you interpret your findings correctly, but you need to share them in a way that is clear for time-short, non-technical personnel. This is important as it ensures any decision-making is based on high-quality, well-understood insights.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"A data analyst in side profile, sitting at a desk and pointing to graphs on a computer screen, showing another person who is standing next to them and smiling\" src=\"\/en\/wp-content\/uploads\/old-blog-uploads\/data-analyst-skills-and-tasks.jpeg\" alt=\"What does a data analyst do? These people are just about to find out.\" width=\"4200\" height=\"2800\" \/><\/p>\n<h2 id=\"what-skills-does-a-data-analyst-need\">6. What skills does a data analyst need?<\/h2>\n<p>In some ways, the skills a data analyst needs vary depending on their role. For instance, knowledge of the business you\u2019re working in is very important. However, as a rule, this is something you can learn on the job.<\/p>\n<p>Before nabbing that first opportunity, though, there\u2019s a core set of skills that all beginner data analysts need. We can divide these into hard skills (or technical abilities) and soft skills (or useful personality traits that help you get the job done).<\/p>\n<h3 id=\"technical-skills-for-data-analysts\">Technical skills for data analysts<\/h3>\n<p>Hard skills sometimes have a steep learning curve. However, with a little discipline, anyone can pick them up. Key hard skills for data analysts include:<\/p>\n<ul>\n<li><strong>Math and statistics:<\/strong> You\u2019ll be mathematically minded. You may have an undergraduate or Master\u2019s degree in an area like applied math, statistics, or computing. However, while qualifications can be useful, they\u2019re not always necessary if you\u2019re a newcomer to the field. As long as you have solid math skills, e.g. algebra and calculus, that could be sufficient.<\/li>\n<li><strong>Programming skills:<\/strong> To create or tweak algorithms that automate data analytics tasks (like parsing or re-structuring large datasets) an element of programming know-how is unavoidable. Scripting languages like Python or MATLAB and statistical computing languages like R and SAS are all popular in data analytics.<\/li>\n<li><strong>Database knowledge:<\/strong> As well as programming languages, you\u2019ll need some understanding of database warehousing software, e.g. Hive, and analytics engines like Spark. You\u2019ll also need to know database query languages like SQL.<\/li>\n<li><strong>Excel skills:<\/strong> Commonly used for transforming raw data into a readable format, or for automating complex calculations, MS Excel is core to any data analyst\u2019s toolset. Be sure to familiarize yourself with its <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/data-analysis-in-excel\/\">key analytical functions<\/a>.<\/li>\n<li><strong>Visualization skills:<\/strong> A core aspect of data analytics is the ability to visualize data with charts and graphs. This helps us identify patterns, correlations, and trends. At the very least, you should be able to create plots using Python, or tables and charts using MS Excel.<\/li>\n<li><strong>Basic machine learning knowledge:<\/strong> As a beginner, nobody will expect you to be an expert in machine learning\u2014it\u2019s an entire discipline in its own right. Nevertheless, the tenets of machine learning underpin many data analytics tasks. You should be familiar with the theory, e.g. supervised learning versus unsupervised learning.<\/li>\n<\/ul>\n<h3 id=\"non-technical-skills-for-data-analysts\">Non-technical skills for data analysts<\/h3>\n<p>While soft skills can be honed with practice, they are generally considered more inherent. You\u2019ll need to have a natural flair for the following:<\/p>\n<ul>\n<li><strong>Communication:<\/strong> Communication is key in any job, but especially in data analytics. Obtaining accurate insights is the priority, but effectively communicating these to wider audiences is vital. You should have excellent interpersonal skills, be able to communicate complex concepts in straightforward terms, and be confident giving presentations and answering questions for non-technical personnel.<\/li>\n<li><strong>Critical thinking:<\/strong> Arguably the most important skill in data analytics, critical thinking is the ability to question what\u2019s in front of you to better understand it. You\u2019ll have a naturally inquisitive mindset, won\u2019t take anything at face value, and will approach tasks using logical reasoning and deduction.<\/li>\n<li><strong>Creative problem-solving:<\/strong> Problem-solving involves applying your reflective way of seeing the world to specific data-related situations or problems. You\u2019ll take a step-by-step approach when defining a problem, devise an approach for solving it, and carry out the necessary subsequent tasks. These tasks will be different every time, so you\u2019ll need a creative mindset.<\/li>\n<li><strong>Ethics:<\/strong> You\u2019ll understand the importance of data privacy, be aware of your personal biases, and be comfortable presenting outcomes\u2014even when these are undesirable or are unlikely to win you any praise. Adhering to a strong ethical code is hugely important. Without it, data can be easily misused, which can have a real-world impact on individuals and groups affected by your work.<\/li>\n<\/ul>\n<p>If you\u2019re dipping a toe into data analytics for the first time, ask yourself: do these skills describe you? If not, don\u2019t worry. While it\u2019s important to appraise your strengths and weaknesses honestly, the most important thing is to be enthusiastic about the field and willing to develop the necessary skills. Nobody hiring a beginner will expect you to be an expert right away.<\/p>\n<h2 id=\"what-tools-do-data-analysts-use\">7. What tools do data analysts use?<\/h2>\n<p>So far, we\u2019ve covered the skills a data analyst needs and the high-level process and tasks they need to carry out. As a beginner, this may feel a bit overwhelming. Fortunately, there\u2019s a huge range of applications and software to help streamline the process. While these require a bit of technical know-how, once you\u2019ve covered the basics, you should find the whole process a lot easier.<\/p>\n<p>Common tools for data analysts include:<\/p>\n<ul>\n<li>MS Excel<\/li>\n<li>Python<\/li>\n<li>R<\/li>\n<li>Databases and management systems<\/li>\n<li>SQL<\/li>\n<\/ul>\n<p>Let\u2019s take a closer look at some of those now.<\/p>\n<h3 id=\"ms-excel-for-data-analytics\">MS Excel for data analytics<\/h3>\n<p>A must-have for any data analyst is MS Excel. Excel allows you to sort data, break it into smaller subsets, and use a wide variety of functions to understand it better.<\/p>\n<p>These functions include <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/how-to-create-a-pivot-table\/\">pivot tables<\/a>, search functions like <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/xlookup-function-excel\/\">XLOOKUP<\/a> and <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/vlookup-function-excel\/\">VLOOKUP<\/a>, the AVERAGE function (which gives you the average of a given range of numbers), and the <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/sumif-function-excel\/\">SUMIF<\/a> function (which lets you calculate the sum of different cells). These tools, along with a great many more, make Excel an invaluable piece of software for beginners and experts alike.<\/p>\n<h3 id=\"python-for-data-analytics\">Python for data analytics<\/h3>\n<p>The general-purpose programming language, Python, has fast become the go-to programming tool for data analysts. This is partly because of its simple syntax, which makes it quick and easy to learn. However, its popularity is also down to the fact that the <a href=\"https:\/\/pypi.org\/\" rel=\"noopener\">Python Package Index<\/a> (PyPI) offers a massive range of software libraries.<\/p>\n<p>Python can be used for almost any aspect of the data analytics process. For instance, <a href=\"https:\/\/pandas.pydata.org\/\" rel=\"noopener\">Pandas<\/a> is excellent for manipulating time-series and other quantitative data. <a href=\"https:\/\/matplotlib.org\/\" rel=\"noopener\">Matplotlib<\/a> is perfect for data visualization. And <a href=\"https:\/\/numpy.org\/\" rel=\"noopener\">NumPy<\/a> is popular for conducting a range of complex mathematical functions. These are just three of the many thousands of Python packages that are available.<\/p>\n<h3 id=\"r-for-data-analytics\">R for data analytics<\/h3>\n<p>R, another programming language, is also common in data analytics.<\/p>\n<p>While R is generally considered more complex to learn than Python, it remains popular due to its historical use in statistical programming (which has benefits in a field like data analytics). While R doesn\u2019t carry out things like image processing with the ease of Python, it has more data analytics functions built in. It\u2019s also often used in scientific fields. Like Python, R also has a library of software, <a href=\"https:\/\/cran.r-project.org\/\" rel=\"noopener\">CRAN<\/a>, with many additional packages available.<\/p>\n<h3 id=\"databases-and-data-management-systems\">Databases and data management systems<\/h3>\n<p>As the variety of data we collect becomes more complex, the way we store and manage these data is also evolving. In data analytics, it\u2019s vital to have an understanding of how databases and data warehouses work. For instance, <a href=\"https:\/\/www.mysql.com\/\" rel=\"noopener\">MySQL<\/a> is a relatively simple type of relational database management system that is commonly used.<\/p>\n<p><a href=\"https:\/\/hadoop.apache.org\/\" rel=\"noopener\">Apache Hadoop<\/a>, meanwhile, is a more complex framework, used to store, manage and process big data using distributed databases. Whether you\u2019re using simple databases or complex infrastructures, they are ultimately unavoidable!<\/p>\n<h3 id=\"structured-query-language-sql\">Structured Query Language (SQL)<\/h3>\n<p><a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/data-analytics\/what-is-sql\/\">SQL<\/a> (sometimes pronounced \u2018sequel\u2019) is a programming language designed to communicate with relational databases. In a world where data is the main currency, this has obvious applications. While relational databases are built using a variety of languages, such as C or C++, SQL allows you to pull, add or edit data without needing knowledge of the database\u2019s native language.<\/p>\n<p>Since most organizations now have information stored digitally or online, SQL is becoming an important language to learn, even for non-analysts. It\u2019s a must-have for those in the field.<\/p>\n<h3 id=\"industry-specific-data-analytics-tools\">Industry-specific data analytics tools<\/h3>\n<p>In addition to the tools already described, the industry is starting to produce ever-more sophisticated sector-specific applications to support data analytics. These tools range from general business intelligence software like <a href=\"https:\/\/powerbi.microsoft.com\/en-us\/\" rel=\"noopener\">Microsoft Power BI<\/a>, to data visualization and dashboarding applications like <a href=\"https:\/\/www.tableau.com\/\" rel=\"noopener\">Tableau<\/a>.<\/p>\n<p>They also include niche products that you\u2019ll only be likely to learn if you work in a specific industry. For instance, <a href=\"https:\/\/www.definitivehc.com\/\" rel=\"noopener\">Definitive Healthcare<\/a> is an analytics platform designed specifically to manage tasks relating to health data.<\/p>\n<h2 id=\"data-analyst-salary\">8.
