Python, SQL and Data Engineer

First, you will learn Python, a scripting language that can be used to write tools for data extraction and transformation, and SQL, a language that can be used to create databases and their structures as well as insert, edit, delete and evaluate data using queries. You will then be familiarized with the requirements of data and databases and the tasks of a data engineer. This includes structuring and providing data as well as selecting the right software and hardware architecture. An insight into the use of artificial intelligence in the profession rounds off the course.

Changes are possible, the course content is updated regularly.

English language skills for the Python certification exam are required.

After the course, you will have a compact, basic knowledge of programming with Python. You will be confident in using the programming language with its classes, libraries and functions.

You can also develop and manage relational databases with SQL. You will create tables and views, formulate queries and process data with suitable SQL commands. You will pay attention to data integrity, use transactions and assign user rights in SQL Server. You will also prepare structured data for analysis and AI-supported evaluations.

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

Data engineers develop and maintain data structures and processes that integrate and process data from various sources and make it available for analysis and other applications. As data-driven business processes become increasingly important, these skills are in demand across all industries.

Your meaningful certificate provides a detailed insight into the qualifications you have acquired and improves your career prospects.

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).
