This is a very COMMON issue that I observe in the projects of aspiring candidates
They download a DATASET from Kaggle or any other website
Export it to a Data Analysis TOOL
And START the project with data cleaning
After cleaning the data, they PLUG it into a dashboard
In the dashboard, they put EVERY column into the visuals
Also they APPLY the filters of top/bottom 10
Once done, they crack their KNUCKLES
And put this project in a list of SUCCESSFULLY completed projects
Over time, I have REVIEWED so many portfolio projects
And I see this ISSUES almost every time
When I go to their portfolio, for every project there is a DASHBOARD
But WHAT should I do after seeing a dashboard?
What is it trying to SAY?
What should I do after SEEING top or bottom 10 cities, states or products?
Every dashboard lacks CONTEXT
And why NOT?
Because they DON'T even know the business problem or problem statement
So the dashboard you created is of NO use
Your job is not just to create DASHBOARDS
Your job would be to create DASHBOARDS to take out important INSIGHTS
And from those insights, you will build RECOMMENDATIONS
And these recommendations will be given to stakeholders as a SOLUTION to their business problem
If they implemented your IDEAS and the problem gets solved
Now you can say your work is DONE
If you are SHOWING bottom 10 states, then what?
You should write the INSIGHTS too
For example, the sales of North India zone are FALLING
The insights can be used like this
Delhi that used to be in TOP 5 states is now in the BOTTOM 10 states
And this might be the REASON why our North India sales are DROPPING so hard
This is just a RANDOM example showing how your charts become UNDERSTANDABLE
Well, everyone can EXTRACT insights from charts
Even a KID can do this after looking at the tallest and smallest bar
The real task is to give RECOMMENDATIONS to solve the BUSINESS problem
And I have NEVER seen this in anyone's portfolio
If you are doing this, then you are easily STANDING out in the crowd
In my PORTFOLIO, I used to keep business problem, insights, dashboard and recommendations
Even in the bullet point of projects in my resume, I included RECOMMENDATIONS
Now this is what you can call a STRONG portfolio
Because your analysis skills are the SAME as those used in the real life by a Data Analyst

Breaking into Data Analysis can be very confusing in 2024!
Should I learn SQL or NoSQL? Tableau or Power BI? Excel or Google Sheets? Python or R?
Fundamental principles are more important than tools:
Understanding data cleaning and preprocessing is more important than SQL vs NoSQL.
Understanding data visualization concepts is more important than Tableau vs Power BI.
Understanding statistical analysis is more important than Excel vs R.
Understanding programming for data manipulation is more important than Python vs R.
Knowing these will allow you to pick up new emerging tools easily.
Stick to fundamentals first.

Knowing Excel, SQL, PowerBI, Python is great.
But if you donโt know how to "sell" your analysis there's a high chance you'll fail.
Here's what to do:
- Come up with questions to investigate.
- Create easy-to-understand answers.
- Explain what to do next.
It's that simple.

The most imp thing data analysts do is to understand the business requirements.
(1) Gathering Data
This means collecting data from different sources. Many a times this is done in collaboration with data engineers and architects hence usually the data analyst doesnโt have to do a lot in this.
(2) Cleaning Data
Going through the data and trying to understand it, making corrections where needed such as removing outliers or data that should not be included in the analysis. This step can take a lot of time, but understanding the data is crucial before you start to process it.
(3) Processing data
The data processing part of the process is where I use my skills and tools to analyze the work and come up with solutions for the problem at hand.
(4) Creating reports for business leaders
As an analyst, a lot of my time goes into creating and maintaining reports/dashboards for stakeholders and business leaders. This means showing the metrics and KPIs in the best manner possible to help drive business decisions.
The best analysts are those that can use data to tell a story.
(5) Collaborating with people
This one is my favorite! As a data analyst, you work with many people across departments, both senior and junior. Youโll also likely collaborate closely with other people who work in data science like data architects and database developers.
Tools I use: Excel,PowerBI,SQL and Python(sometimes)

SQL Basics for Beginners: Must-Know Concepts
1. What is SQL?
SQL (Structured Query Language) is a standard language used to communicate with databases. It allows you to query, update, and manage relational databases by writing simple or complex queries.
2. SQL Syntax
SQL is written using statements, which consist of keywords like
- SQL keywords are not case-sensitive, but it's common to write them in uppercase (e.g.,
3. SQL Data Types
Databases store data in different formats. The most common data types are:
-
-
-
-
4. Basic SQL Queries
Here are some fundamental SQL operations:
- SELECT Statement: Used to retrieve data from a database.
- WHERE Clause: Filters data based on conditions.
- ORDER BY: Sorts data in ascending (
- LIMIT: Limits the number of rows returned.
5. Filtering Data with WHERE Clause
The
You can use comparison operators like:
-
-
-
-
6. Aggregating Data
SQL provides functions to summarize or aggregate data:
- COUNT(): Counts the number of rows.
- SUM(): Adds up values in a column.
- AVG(): Calculates the average value.
- GROUP BY: Groups rows that have the same values into summary rows.
7. Joins in SQL
Joins combine data from two or more tables:
- INNER JOIN: Retrieves records with matching values in both tables.
- LEFT JOIN: Retrieves all records from the left table and matched records from the right table.
8. Inserting Data
To add new data to a table, you use the

1. What is SQL?
SQL (Structured Query Language) is a standard language used to communicate with databases. It allows you to query, update, and manage relational databases by writing simple or complex queries.
2. SQL Syntax
SQL is written using statements, which consist of keywords like
SELECT, FROM, WHERE, etc., to perform operations on the data.- SQL keywords are not case-sensitive, but it's common to write them in uppercase (e.g.,
SELECT, FROM).3. SQL Data Types
Databases store data in different formats. The most common data types are:
-
INT (Integer): For whole numbers.-
VARCHAR(n) or TEXT: For storing text data.-
DATE: For dates.-
DECIMAL: For precise decimal values, often used in financial calculations.4. Basic SQL Queries
Here are some fundamental SQL operations:
- SELECT Statement: Used to retrieve data from a database.
SELECT column1, column2 FROM table_name;
- WHERE Clause: Filters data based on conditions.
SELECT * FROM table_name WHERE condition;
- ORDER BY: Sorts data in ascending (
ASC) or descending (DESC) order.SELECT column1, column2 FROM table_name ORDER BY column1 ASC;
- LIMIT: Limits the number of rows returned.
SELECT * FROM table_name LIMIT 5;
5. Filtering Data with WHERE Clause
The
WHERE clause helps you filter data based on a condition:SELECT * FROM employees WHERE salary > 50000;
You can use comparison operators like:
-
=: Equal to-
>: Greater than-
<: Less than-
LIKE: For pattern matching6. Aggregating Data
SQL provides functions to summarize or aggregate data:
- COUNT(): Counts the number of rows.
SELECT COUNT(*) FROM table_name;
- SUM(): Adds up values in a column.
SELECT SUM(salary) FROM employees;
- AVG(): Calculates the average value.
SELECT AVG(salary) FROM employees;
- GROUP BY: Groups rows that have the same values into summary rows.
SELECT department, AVG(salary) FROM employees GROUP BY department;
7. Joins in SQL
Joins combine data from two or more tables:
- INNER JOIN: Retrieves records with matching values in both tables.
SELECT employees.name, departments.department
FROM employees
INNER JOIN departments
ON employees.department_id = departments.id;
- LEFT JOIN: Retrieves all records from the left table and matched records from the right table.
SELECT employees.name, departments.department
FROM employees
LEFT JOIN departments
ON employees.department_id = departments.id;
8. Inserting Data
To add new data to a table, you use the
INSERT INTO statement: INSERT INTO employees (name, position, salary) VALUES ('John Doe', 'Analyst', 60000);
9. Updating Data
You can update existing data in a table using the
UPDATE statement:UPDATE employees SET salary = 65000 WHERE name = 'John Doe';
10. Deleting Data
To remove data from a table, use the
DELETE statement:DELETE FROM employees WHERE name = 'John Doe';
