Spreadsheets & Visualisation
Excel and Power BI are the two tools most entry-level analyst roles test on day one.
Microsoft Excel for Data Analysis
Excel remains the undisputed backbone of corporate data analytics, and most entry-level interviews will test your spreadsheet proficiency before anything else. This comprehensive course skips the basic data entry and dives straight into the advanced analytical tools that employers actually care about. You will learn how to write complex nested formulas, master VLOOKUP and XLOOKUP functions, and build dynamic pivot tables that can summarize thousands of rows of data instantly. By the end of this course, you will be able to take messy, unstructured datasets and transform them into clean, actionable business reports that drive decision-making.
Introduction to Power BI
Once your data is clean and analyzed, you need to present it in a way that non-technical stakeholders can easily understand. This beginner-friendly course introduces you to Microsoft Power BI, one of the most widely used business intelligence tools in the corporate world. You will learn how to connect raw data sources, build relational data models, and create interactive, visually compelling dashboards. Understanding how to tell a story with data through dynamic charts and graphs is what separates a good analyst from a great one, and this course provides the perfect starting point.
Mastering Financial Statement Analysis
Data analysts do not work in a vacuum; they often collaborate closely with finance and operations teams to evaluate corporate performance. This specialized course bridges the gap between raw data analysis and financial literacy. You will learn how to read, interpret, and extract insights from balance sheets, income statements, and cash flow reports. Developing this commercial awareness allows you to translate data trends into tangible business outcomes, making you a highly valuable asset to management teams and financial directors.
SQL & Databases
SQL is the single most important technical skill for a data analyst. Start here.
Introduction to Database Concepts
Before you can write complex queries to extract data, you must understand how modern relational databases are fundamentally structured. This foundational course covers the core architecture of databases, explaining critical concepts like primary keys, foreign keys, table schemas, and data normalization. It lays the essential groundwork for understanding how data is stored, organized, and linked across different tables, ensuring that when you do start writing SQL, you understand exactly how the underlying system is executing your requests.
Diploma in Databases and T-SQL
SQL (Structured Query Language) is the single most important technical skill for any data analyst, period. This comprehensive diploma moves you from writing basic SELECT statements to mastering complex JOINs, subqueries, and data aggregation techniques using T-SQL. You will gain the fluency needed to extract precisely the data you need from massive, multi-table corporate databases. Employers expect analysts to be entirely self-sufficient when pulling data, and this diploma provides the rigorous, practical training required to meet that expectation on day one.
Databases - DML Statements and SQL Server Administration
While extracting data is crucial, understanding how to manipulate it safely is equally important. This course focuses specifically on Data Manipulation Language (DML) within a SQL Server environment. You will learn the correct procedures for safely inserting new records, updating existing data, and executing controlled deletions without risking dataset corruption. This knowledge of database integrity and safe data handling practices is highly attractive to hiring managers who need analysts they can trust with production databases.
Python for Data
Python handles datasets, automates reporting, and unlocks machine learning.
Python for Beginners
As datasets grow too large for Excel to handle efficiently, Python has rapidly become the programming language of choice for data professionals. This accessible primer introduces you to Python syntax and core data structures, specifically focusing on how the language is used to automate repetitive data tasks. You will learn how to set up your environment, write basic scripts, and understand how Python can drastically reduce the time spent on manual data cleaning and processing.
Diploma in Python Programming
Taking your skills to the next level, this comprehensive diploma dives deeper into Python's powerful capabilities. You will master the logic and scripting techniques required to interact with external APIs, scrape web data, and handle complex data transformations. It covers essential programming concepts like loops, conditional logic, and error handling, giving you the robust technical foundation needed to utilize advanced data science libraries like Pandas and NumPy in your future projects.
Machine Learning with Artificial Intelligence
For ambitious analysts looking to future-proof their careers, moving from historical data analysis to predictive modeling is the natural next step. This introductory course demystifies machine learning, showing you how algorithms can recognize complex patterns within large datasets. You will explore the differences between supervised and unsupervised learning, and understand how predictive models are trained, tested, and deployed to forecast future trends and behaviors in real-world business scenarios.

What Skills Do You Need to Become a Data Analyst?
Most data analyst roles expect a core set of tools and skills. Here is the standard learning path, from beginner to job-ready.
| Tool | What You Use It For | Level |
|---|---|---|
| Excel / Google Sheets | Cleaning, sorting, and summarising small datasets | Beginner |
| SQL | Querying databases to extract and filter data at scale | Beginner to Intermediate |
| Python (Pandas / NumPy) | Automating analysis and working with large, complex datasets | Intermediate |
| Power BI / Tableau | Building dashboards and visual reports for stakeholders | Intermediate |
| Machine Learning basics | Predictive modelling and pattern recognition in data | Advanced |
Do You Need Coding to Become a Data Analyst?
Not always, but learning Python and SQL will make you significantly more competitive.
You can start without coding:
- Excel and Google Sheets for basic data manipulation
- Online dashboarding tools with drag-and-drop interfaces
- Basic reporting and data interpretation skills
However, learning Python and SQL will:
- Increase your job opportunities significantly
- Let you work with larger, more complex datasets
- Make you more competitive at salary negotiation
- Open paths into data science and machine learning
How to Choose the Right Course
A clear starting strategy prevents wasted time and dropped momentum.
Start with the Basics
Begin with introductory database and SQL courses before jumping into Python. Understanding how data is stored and queried is the most foundational skill.

Frequently Asked Questions
Do you need coding experience to become a data analyst?
Not at first. You can start with Excel and basic data tools with no coding background. However, learning SQL and Python will significantly increase your job prospects, salary ceiling, and ability to work with larger datasets. Most employers expect at least basic SQL from entry-level analysts.
How long does it take to learn data analytics from scratch?
With consistent study (1 to 2 hours per day), you can cover the fundamentals, SQL, basic Python, and data interpretation, within 3 to 6 months. Completing several certificates along the way gives you tangible proof of progress for your CV.
Is SQL really necessary for data analysts?
Yes, it is arguably the most important tool. Most real-world data lives in relational databases. SQL lets you extract, filter, group, and join that data directly. It is typically the first technical skill employers test for in data analyst interviews.
Are free data analytics certificates worth adding to a CV?
Absolutely, especially early in your career. They show initiative, demonstrate that you have covered specific topics, and give interviewers a clear talking point. Pairing a certificate with a personal project (even a simple dataset analysis on GitHub) is even more compelling.
What is the difference between a data analyst and a data scientist?
A data analyst focuses on interpreting existing data to answer business questions using tools like SQL, Excel, and visualisation software. A data scientist goes further, building predictive models, working with unstructured data, and applying machine learning techniques. Most data scientists start as analysts.
