What Is A Data Warehouse?

A data warehouse is a persistent set of data that is intended for analysis and decision support. Data warehouses of this type are therefore very important for companies as they are used to analyze competitiveness, optimize processes and adjust the strategic direction of the company. This database is used to record the different types of information, data and events that occur continuously in the company. When these are brought together into a coherent whole, a so-called data cluster is created. When new business decisions need to be made, this data is an important tool in the decision-making process. Data warehouses are used to create such data sets. They collect data from different sources to compile it in a uniform format and prepare it for research. Data protection rules must always be respected when collecting this data. This applies in particular to personal data.

One of the most important skills a data warehouse analyst needs is extensive experience in software development and project management. In addition to database experience, you should also have good communication and abstraction skills. You must also be able to work under pressure, work in a team and be service oriented. The ability to work independently, a preference for mathematical procedures and confidence in the use of computers are important aspects of this position.

Tasks Of The Data Warehouse Analyst

The data warehouse analyst analyses and manages all relevant company-specific data stored in the data warehouse. An important task here is to clean, prepare and store the data so that all employees of the company can access it at the right time.

The data warehouse analyst is therefore the link between management and IT.

Another task is to classify the collected data according to importance and relevance using business intelligence software.

This requires knowledge of different database systems such as SAS or Oracle.

This means that the data warehouse analyst must have a broad and diverse knowledge in different areas.

Where Can I Work As A Database Analyst?

This includes multinational companies and large corporations. They then work in the marketing department or IT department, which can always vary slightly, but this should be clearly stated in the job advertisement or at least in the interview.

However, it is also possible to work in this profession without a university degree.
