Creator Story

This course was created by Anastasiia Ovsiienko, a Data Analyst who understands how confusing database work can feel at the beginning. While working with tables, queries, and large datasets, she noticed one common issue: learners often do not need more information, they need a better learning order. That is why Anastasiia created a course where each topic is explained gradually, from basic ideas to examples based on real work situations. The mission of the course is to help students develop database skills through structured materials, exercises, and examples they can review at their own pace.

Credentials

Anastasiia Ovsiienko has experience in data analysis, reporting, SQL queries, and organizing databases for work processes. She has worked with datasets of different sizes, helped teams arrange information more clearly, and created analytical materials for internal use. Her teaching approach is based on simple explanations, organized tasks, and examples that show how tables, relationships, and queries work together.

Personal Bio

Anastasiia became interested in data because she enjoyed finding order inside complex information. Over time, she began working more deeply with databases: building tables, checking data quality, writing queries, and preparing materials for teams. In this course, she gathered her experience into short, understandable modules so students can study the topic without unnecessary overload.
