What this course is about
Develop an end-to-end understanding of how organisations use data to make decisions. This Advanced Diploma in Data Analytics is taught through live 1-on-1 online classes, where your personal teacher connects business questions with data preparation, analysis and communication. You learn to move from an unclear question to a clean dataset, a defensible analysis and a recommendation that a non-technical manager can understand.
The curriculum combines Excel for practical analysis, SQL for querying relational data, statistics for interpreting patterns, Python basics for repeatable work, and Power BI or Tableau for visual storytelling. Projects cover cleaning data, joining tables, calculating summaries, comparing segments, checking assumptions and building dashboards. You also practise documenting methods so another person can follow your reasoning. You also practise concise data notes.
This broader data analytics course for freshers is useful when you want more than one reporting tool. A project portfolio can include an Excel analysis, SQL business query, Python notebook and interactive dashboard, with teacher feedback at each stage. Osian Academy provides a completion certificate. These outputs support interview discussion.
What you’ll be able to do
- Analyse business data with structured Excel formulas, pivots and charts
- Query, filter, join and summarise relational data using SQL
- Apply descriptive statistics to compare groups and interpret variation
- Use Python basics to clean data and repeat simple analytical tasks

Before you enrol
No prior coding is required, although comfort with spreadsheets is useful. Python is taught at a practical beginner level, while SQL and statistics are introduced through business examples.
A laptop with a browser, spreadsheet software, a SQL practice environment and Python notebook setup is recommended. The teacher will guide installation and may use Power BI or Tableau according to the project setup.
You can build a connected portfolio covering Excel analysis, SQL queries, a Python data cleaning exercise and a Power BI or Tableau dashboard. The emphasis is on explaining the question, method, finding and recommendation.
The programme mirrors common junior work: preparing files, querying data, checking patterns, maintaining dashboards and explaining results. Placement support includes resume help, mock interviews and referrals, but no job outcome is guaranteed.
The diploma covers a wider analytics workflow across Excel, SQL, statistics, Python basics and visualisation. The Power BI course goes deeper into Power Query, modelling, DAX, dashboard design and publishing.
It is an Osian Academy professional course with a certificate on completion, not a university degree. It does not claim to include official Microsoft, Tableau or Python certification.
