A data analyst processes and interprets data to provide valuable insights to companies. They analyze past developments, identify trends and make forecasts. To do this, the data analyst collects data from various sources, cleans it and structures it for further analysis.
In a data analyst's day-to-day work, the first task is to collect data. To do this, they use both internal sources, such as sales figures or customer data, and external sources, such as market research reports. This data is then checked for errors and cleaned up before it can be analyzed. With the help of statistical methods and modern analysis tools such as Python, SQL or Power BI, the analyst recognizes patterns and correlations.
The results of the analysis are then prepared in the form of dashboards, reports or presentations so that non-experts can also understand the insights gained. A typical example: an online store wants to know why certain products are selling less well. The data analyst examines sales figures, customer feedback and external factors such as market developments and makes specific recommendations for pricing, marketing strategies or product improvements.
In this way, the data analyst makes a decisive contribution to enabling companies to adapt their business strategies in a targeted and well-founded manner.

The work of a data analyst requires a wide range of professional and personal skills. In addition to in-depth technical knowledge, it is important to develop analytical skills and a precise way of working in order to master the complex tasks involved in this profession.
Analytical thinking and problem-solving skills
Data analysts are experts at recognizing patterns in large data sets and drawing well-founded conclusions from this information. They not only have to understand data, but also process it in such a way that it provides valuable insights for the company. A good example is the ability to discover connections in seemingly random or chaotic data patterns and to make precise recommendations based on these.
Technical expertise
A data analyst must be familiar with various programming languages and tools. The most important language is SQL for retrieving and editing data from databases. Python and R are the commonly used programming languages for statistical analysis and data mining. Knowledge of data visualization using tools such as Tableau or Power BI is also crucial to present the results in an understandable way.
Communication skills
An often-underestimated skill for a data analyst is communication skills. It is not enough just to analyze data. The insights gained must be communicated in an understandable and convincing way to stakeholders and decision-makers. A data analyst must be able to explain the meaning of the figures in such a way that non-experts can also understand the results.
Attention to detail and diligence
Since small errors in data collection or analysis can lead to false conclusions, attention to detail is essential. Data analysts must work very precisely, identify sources of error and, if necessary, clean data to achieve accurate and reliable results.
Willingness to learn
In a fast-paced, technologically advanced world, it is important to stay up to date. The willingness to learn is therefore an essential skill, as analytical tools and methods are constantly evolving.

The day-to-day work of a data analyst is varied and full of exciting challenges. The main task is to filter out valuable information from large and often unstructured data volumes and to make this information usable for strategic decisions. This requires both technical skills and strong problem-solving abilities.
As a data analyst, your main task is to collect and analyze data and use it to derive insights that are relevant for the company. You start with data acquisition by identifying relevant data sources such as sales figures, customer data or market research and ensuring that they are accurate and complete. The quality of the data is crucial, which is why a significant part of your work also involves data cleansing to eliminate errors or inconsistencies.
You then use modern analytics tools such as Python, R, SQL or Power BI to analyze the data. Your job is to identify patterns and correlations and understand how certain factors affect the business. This statistical evaluation helps you to create accurate forecasts and trend analysis that support the company in planning and decision-making.
Another key activity is the processing and visualization of the results. You create comprehensible dashboards or reports that convert complex data into easy-to-understand and visually appealing formats. This enables non-technical decision-makers to understand the data and make strategic decisions based on it.
Additionally, you are often involved in project management processes and work closely with other departments such as marketing, finance, or IT to ensure that data analysis is aligned with company goals. Your recommendations often influence important business functions such as pricing, product development, or customer retention.

A solid educational background is crucial to get started as a data analyst. The usual route is to complete a bachelor's or master's degree in business informatics, mathematics, statistics, data science or a related field. A sound understanding of mathematical concepts, statistics and data models forms the basis for successful work as a data analyst.
Practical experience is also of great importance. Many companies are looking for applicants with practical knowledge of database management, statistical tools, and programming languages such as Python, R, or SQL. Internships or student jobs in data analysis offer a valuable opportunity to apply theoretical knowledge and build a network in practice. Entry-level positions are often as junior data analysts, where you gain initial experience before you can advance to a senior data analyst or data scientist.
In addition, certified training courses are a good way to stand out from other applicants and acquire specialized knowledge. Programs such as Google Data Analytics, Microsoft Power BI or Data Science courses offer in-depth insights into specific tools and methods of data analysis.
A strong willingness to learn is also important, as the tools and techniques used in data analysis are constantly evolving. Those who keep up to date will have excellent prospects in this rapidly growing professional field.

A data analyst starts with an entry-level salary of €35,000 to €45,000 per year. However, this depends on various factors, such as the size of the company, the industry and the location. In large cities like Berlin, Frankfurt or Munich, starting salaries can be slightly higher because there is a particularly high demand for data analysts there. In addition, knowledge of special tools such as SQL, Python or R has a positive influence on starting salaries. Those who have already gained practical experience through internships or working student jobs can benefit from a higher salary.
With a few years of professional experience, a data analyst's salary increases significantly. After 3 to 5 years of professional experience, the salary can increase to €50,000 to €70,000 annually. In larger companies, especially in the tech industry or in international corporations, salaries at the upper end are also possible. If a data analyst has acquired additional in-depth knowledge in specific areas such as machine learning, data science or big data, salary expectations increase significantly. In particular, analysts who specialize in data visualization or business intelligence can find very good conditions in the job market.
In higher positions such as lead analyst, senior data scientist or chief data officer (CDO), salaries can increase significantly and often range from €80,000 to €120,000 per year. For such positions, in-depth technical knowledge and extensive experience in team leadership and project management are required. In some cases, especially at very successful companies or in the tech industry, salaries can be even higher, especially when bonuses or profit sharing are added. Location also plays a role: in international tech hubs or at companies in the fintech industry, top salaries of over €150,000 per year are possible.
