Changes are possible. The course content is updated regularly.

After the course, you will have a compact, basic knowledge of programming with Python. You will be able to use the programming language with its classes, libraries and functions with confidence.

You will also be able to build and manage relational databases with SQL, create views and execute complex queries, including using SQL functions. The course is taught on the Microsoft SQL server using the Microsoft SQL Server Management Studio.

You are also proficient in processes relating to the consolidation, preparation, enrichment and forwarding of data.

Furthermore, you can analyse, visualize and manage data. You also understand the use of dashboards and text mining.

The course is aimed at people with a degree in computer science, business informatics, mathematics, business administration or comparable qualifications.

The versatility of Python makes employees with the relevant skills attractive in numerous industries and companies. People with programming skills in Python are particularly sought after in web development, machine learning and data analysis.

By creating and developing databases, companies ensure efficient sorting, logical structuring and permanent documentation of important data. Additional knowledge as an SQL database specialist or administrator will complement your knowledge accordingly and round off your profile.

Data engineers are the interface between the specialist and IT departments. As more and more large and medium-sized companies are using data analysis, they are in demand in industry and commerce as well as in the service and finance sectors.

As companies also have to manage and structure ever-increasing volumes of data in order to evaluate and target their business processes, data analysis skills are in demand in all sectors.

Didactic concept

Your lecturers are highly qualified both professionally and didactically and will teach you from the first to the last day (no self-study system).

You will learn in effective small groups. The courses usually consist of 6 to 25 participants. The general lessons are supplemented by numerous practical exercises in all course modules. The practice phase is an important part of the course, as it is during this time that you process what you have just learned and gain confidence and routine in its application. The final section of the course involves a project, a case study or a final exam.

 

Virtual classroom alfaview®

Lessons take place using modern alfaview® video technology - either from the comfort of your own home or at our premises at Bildungszentrum. The entire course can see each other face-to-face via alfaview®, communicate with each other in lip-sync voice quality and work on joint projects. Of course, you can also see and talk to your connected trainers live at any time and you will be taught by your lecturers in real time for the entire duration of the course. The lessons are not e-learning, but real live face-to-face lessons via video technology.

 

The courses at alfatraining are funded by Agentur für Arbeit and are certified in accordance with the AZAV approval regulation. When submitting a Bildungsgutscheinor Aktivierungs- und Vermittlungsgutschein, the entire course costs are usually covered by your funding body.
Funding is also possible via Europäischen Sozialfonds (ESF), Deutsche Rentenversicherung (DRV) or regional funding programs. As a regular soldier, you have the option of attending further training courses via Berufsförderungsdienst (BFD). Companies can also have their employees qualified via funding from Agentur für Arbeit (Qualifizierungschancengesetz).
