Beyond the Buzzword: Your Roadmap to Gaining Real Knowledge in Data Science

Data science. It's a field bursting with innovation, high demand, and the promise of solving real-world problems. But for newcomers, the sheer breadth of tools, techniques, and theoretical concepts can feel overwhelming. So, how do you gain real knowledge in data science, moving beyond surface-level understanding to truly master the craft?

It's not just about watching a few tutorials or reading a single book. True data science knowledge is built on a multi-faceted approach, combining theoretical understanding with practical application. Here’s a roadmap to guide your journey:

1. Build a Strong Foundational Core

Before you dive into the flashy algorithms, solidify your bedrock. This is non-negotiable.

Mathematics & Statistics: This is the language of data science.

Linear Algebra: Essential for understanding algorithms from linear regression to neural networks.

Calculus: Key for understanding optimization algorithms (gradient descent!) and the inner workings of many machine learning models.

Probability & Statistics: Absolutely critical for data analysis, hypothesis testing, understanding distributions, and interpreting model results. Learn about descriptive statistics, inferential statistics, sampling, hypothesis testing, confidence intervals, and different probability distributions.

Programming: Python and R are the reigning champions.

Python: Learn the fundamentals, then dive into libraries like NumPy (numerical computing), Pandas (data manipulation), Matplotlib/Seaborn (data visualization), and Scikit-learn (machine learning).

R: Especially strong for statistical analysis and powerful visualization (ggplot2). Many statisticians prefer R.

Databases (SQL): Data lives in databases. Learn to query, manipulate, and retrieve data efficiently using SQL. This is a fundamental skill for any data professional.

Where to learn: Online courses (Xaltius Academy, Coursera, edX, Udacity), textbooks (e.g., "Think Stats" by Allen B. Downey, "An Introduction to Statistical Learning"), Khan Academy for math fundamentals.

2. Dive into Machine Learning Fundamentals

Once your foundation is solid, explore the exciting world of machine learning.

Supervised Learning: Understand classification (logistic regression, decision trees, SVMs, k-NN, random forests, gradient boosting) and regression (linear regression, polynomial regression, SVR, tree-based models).

Unsupervised Learning: Explore clustering (k-means, hierarchical clustering, DBSCAN) and dimensionality reduction (PCA, t-SNE).

Model Evaluation: Learn to rigorously evaluate your models using metrics like accuracy, precision, recall, F1-score, AUC-ROC for classification, and MSE, MAE, R-squared for regression. Understand concepts like bias-variance trade-off, overfitting, and underfitting.

Cross-Validation & Hyperparameter Tuning: Essential techniques for building robust models.

Where to learn: Andrew Ng's Machine Learning course on Coursera is a classic. "Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow" by Aurélien Géron is an excellent practical guide.

3. Get Your Hands Dirty: Practical Application is Key!

Theory without practice is just information. You must apply what you learn.

Work on Datasets: Start with well-known datasets on platforms like Kaggle (Titanic, Iris, Boston Housing). Progress to more complex ones.

Build Projects: Don't just follow tutorials. Try to solve a real-world problem from start to finish. This involves:

Problem Definition: What are you trying to predict/understand?

Data Collection/Acquisition: Where will you get the data?

Exploratory Data Analysis (EDA): Understand your data, find patterns, clean messy parts.

Feature Engineering: Create new, more informative features from existing ones.

Model Building & Training: Select and train appropriate models.

Model Evaluation & Tuning: Refine your model.

Communication: Explain your findings clearly, both technically and for a non-technical audience.

Participate in Kaggle Competitions: This is an excellent way to learn from others, improve your skills, and benchmark your performance.

Contribute to Open Source: A great way to learn best practices and collaborate.

4. Specialize and Deepen Your Knowledge

As you progress, you might find a particular area of data science fascinating.

This SQL Trick Cut My Query Time by 80%

How One Simple Change Supercharged My Database Performance

If you work with SQL, you’ve probably spent hours trying to optimize slow-running queries — tweaking joins, rewriting subqueries, or even questioning your career choices. I’ve been there. But recently, I discovered a deceptively simple trick that cut my query time by 80%, and I wish I had known it sooner.

Here’s the full breakdown of the trick, how it works, and how you can apply it right now.

🧠 The Problem: Slow Query in a Large Dataset

I was working with a PostgreSQL database containing millions of records. The goal was to generate monthly reports from a transactions table joined with users and products. My query took over 35 seconds to return, and performance got worse as the data grew.

Here’s a simplified version of the original query:

sql

SELECT

u.user_id,

SUM(t.amount) AS total_spent

FROM

transactions t

JOIN

users u ON t.user_id = u.user_id

WHERE

t.created_at >= '2024-01-01'

AND t.created_at < '2024-02-01'

GROUP BY

u.user_id, http://u.name;

No complex logic. But still painfully slow.

⚡ The Trick: Use a CTE to Pre-Filter Before the Join

The major inefficiency here? The join was happening before the filtering. Even though we were only interested in one month’s data, the database had to scan and join millions of rows first — then apply the WHERE clause.

✅ Solution: Filter early using a CTE (Common Table Expression)

Here’s the optimized version:

sql

WITH filtered_transactions AS (

SELECT *

FROM transactions

WHERE created_at >= '2024-01-01'

AND created_at < '2024-02-01'

)

SELECT

u.user_id,

SUM(t.amount) AS total_spent

FROM

filtered_transactions t

JOIN

users u ON t.user_id = u.user_id

GROUP BY

u.user_id, http://u.name;

Result: Query time dropped from 35 seconds to just 7 seconds.

That’s an 80% improvement — with no hardware changes or indexing.

🧩 Why This Works

Databases (especially PostgreSQL and MySQL) optimize join order internally, but sometimes they fail to push filters deep into the query plan.

By isolating the filtered dataset before the join, you:

Reduce the number of rows being joined

Shrink the working memory needed for the query

Speed up sorting, grouping, and aggregation

This technique is especially effective when:

You’re working with time-series data

Joins involve large or denormalized tables

Filters eliminate a large portion of rows

🔍 Bonus Optimization: Add Indexes on Filtered Columns

To make this trick even more effective, add an index on created_at in the transactions table:

sql

CREATE INDEX idx_transactions_created_at ON transactions(created_at);

This allows the database to quickly locate rows for the date range, making the CTE filter lightning-fast.

🛠 When Not to Use This

While this trick is powerful, it’s not always ideal. Avoid it when:

Your filter is trivial (e.g., matches 99% of rows)

The CTE becomes more complex than the base query

Your database’s planner is already optimizing joins well (check the EXPLAIN plan)

🧾 Final Takeaway

You don’t need exotic query tuning or complex indexing strategies to speed up SQL performance. Sometimes, just changing the order of operations — like filtering before joining — is enough to make your query fly.

“Think like the database. The less work you give it, the faster it moves.”

If your SQL queries are running slow, try this CTE filtering trick before diving into advanced optimization. It might just save your day — or your job.

Microsoft Fabric data warehouse

Microsoft Fabric data warehouse

What Is Microsoft Fabric and Why You Should Care?

Unified Software as a Service (SaaS), offering End-To-End analytics platform

Gives you a bunch of tools all together, Microsoft Fabric OneLake supports seamless integration, enabling collaboration on this unified data analytics platform

Scalable Analytics

Accessibility from anywhere with an internet connection

Streamlines collaboration among data professionals

Empowering low-to-no-code approach

Components of Microsoft Fabric

Fabric provides comprehensive data analytics solutions, encompassing services for data movement and transformation, analysis and actions, and deriving insights and patterns through machine learning. Although Microsoft Fabric includes several components, this article will use three primary experiences: Data Factory, Data Warehouse, and Power BI.

Lake House vs. Warehouse: Which Data Storage Solution is Right for You?

In simple terms, the underlying storage format in both Lake Houses and Warehouses is the Delta format, an enhanced version of the Parquet format.

Usage and Format Support

A Lake House combines the capabilities of a data lake and a data warehouse, supporting unstructured, semi-structured, and structured formats. In contrast, a data  Warehouse supports only structured formats.

When your organization needs to process big data characterized by high volume, velocity, and variety, and when you require data loading and transformation using Spark engines via notebooks, a Lake House is recommended. A Lakehouse can process both structured tables and unstructured/semi-structured files, offering managed and external table options. Microsoft Fabric OneLake serves as the foundational layer for storing structured and unstructured data Notebooks can be used for READ and WRITE operations in a Lakehouse. However, you cannot connect to a Lake House with an SQL client directly, without using SQL endpoints.

On the other hand, a Warehouse excels in processing and storing structured formats, utilizing stored procedures, tables, and views. Processing data in a Warehouse requires only T-SQL knowledge. It functions similarly to a typical RDBMS database but with a different internal storage architecture, as each table’s data is stored in the Delta format within OneLake. Users can access Warehouse data directly using any SQL client or the in-built graphical SQL editor, performing READ and WRITE operations with T-SQL and its elements like stored procedures and views. Notebooks can also connect to the Warehouse, but only for READ operations.

An SQL endpoint is like a special doorway that lets other computer programs talk to a database or storage system using a language called SQL. With this endpoint, you can ask questions (queries) to get information from the database, like searching for specific data or making changes to it. It’s kind of like using a search engine to find things on the internet, but for your data stored in the Fabric system. These SQL endpoints are often used for tasks like getting data, asking questions about it, and making changes to it within the Fabric system.

Choosing Between Lakehouse and Warehouse

The decision to use a Lakehouse or Warehouse depends on several factors:

Migrating from a Traditional Data Warehouse: If your organization does not have big data processing requirements, a Warehouse is suitable.

Migrating from a Mixed Big Data and Traditional RDBMS System: If your existing solution includes both a big data platform and traditional RDBMS systems with structured data, using both a Lakehouse and a Warehouse is ideal. Perform big data operations with notebooks connected to the Lakehouse and RDBMS operations with T-SQL connected to the Warehouse.

Note: In both scenarios, once the data resides in either a Lakehouse or a Warehouse, Power BI can connect to both using SQL endpoints. 

A Glimpse into the Data Factory Experience in Microsoft Fabric

In the Data Factory experience, we focus primarily on two items: Data Pipeline and Data Flow.

Data Pipelines

Used to orchestrate different activities for extracting, loading, and transforming data.

Ideal for building reusable code that can be utilized across other modules.

Enables activity-level monitoring.

To what can we compare Data Pipelines ?

microsoft fabric data pipelines Data Pipelines are similar, but not the same as:

Informatica -> Workflows

ODI -> Packages

Dataflows

Utilized when a GUI tool with Power Query UI experience is required for building Extract, Transform, and Load (ETL) logic.

Employed when individual selection of source and destination components is necessary, along with the inclusion of various transformation logic for each table.

To what can we compare Data Flows ?

Dataflows are similar, but not same as : 

Informatica -> Mappings

ODI -> Mappings / Interfaces

Are You Ready to Migrate Your Data Warehouse to Microsoft Fabric?

Here is our solution for implementing the Medallion Architecture with Fabric data Warehouse:

Creation of New Workspace

We recommend creating separate workspaces for Semantic Models, Reports, and Data Pipelines as a best practice.

Creation of Warehouse and Lakehouse

Follow the on-screen instructions to setup new Lakehouse and a Warehouse:

Configuration Setups

Create a configurations.json file containing parameters for data pipeline activities:

Source schema, buckets, and path

Destination warehouse name

Names of warehouse layers bronze, silver and gold – OdsStage,Ods and Edw

List of source tables/files in a specific format

Source System Id’s for different sources

Below is the screenshot of the (config_variables.json) : 

File Placement

Place the configurations.json and SourceTableList.csv files in the Fabric Lakehouse.

SourceTableList will have columns such as – SourceSystem, SourceDatasetId, TableName, PrimaryKey, UpdateKey, CDCColumnName, SoftDeleteColumn, ArchiveDate, ArchiveKey

Data Pipeline Creation

Create a data pipeline to orchestrate various activities for data extraction, loading, and transformation. Below is the screenshot of the Data Pipeline and here you can see the different activities like – Lookup, ForEach, Script, Copy Data and Stored Procedure

Bronze Layer Loading

Develop a dynamic activity to load data into the Bronze Layer (OdsStage schema in Warehouse). This layer truncates and reloads data each time. 

We utilize two activities in this layer: Script Activity and Copy Data Activity. Both activities receive parameterized inputs from the Configuration file and SourceTableList file. The Script activity drops the staging table, and the Copy Data activity creates and loads data into the OdsStage table. These activities are reusable across modules and feature powerful capabilities for fast data loading.

Silver Layer Loading

Establish a dynamic activity to UPSERT data into the Silver layer (Ods schema in Warehouse) using a stored procedure activity. This procedure takes parameterized inputs from the Configuration file and SourceTableList file, handling both UPDATE and INSERT operations. This stored procedure is reusable. At this time, MERGE statements are not supported by Fabric Warehouse. However, this feature may be added in the future.

Control Table Creation

Create a control table in the Warehouse with columns containing Sequence Numbers and Procedure Names to manage dependencies between Dimensions, Facts, and Aggregate tables. And finally fetch the values using a Lookup activity.

Gold Layer Loading

To load data into the Gold Layer (Edw schema in the warehouse), we develop individual stored procedures to UPSERT (UPDATE and INSERT) data for each dimension, fact, and aggregate table. While Dataflow can also be used for this task, we prefer stored procedures to handle the nature of complex business logic.

Dashboards and Reporting

Fabric includes the Power BI application, which can connect to the SQL endpoints of both the Lakehouse and Warehouse. These SQL endpoints allow for the creation of semantic models, which are then used to develop reports and applications. In our use case, the semantic models are built from the Gold layer (Edw schema in Warehouse) tables.

Upcoming Topics Preview

In the upcoming articles, we will cover topics such as notebooks, dataflows, lakehouse, security and other related subjects.

Conclusion

microsoft Fabric data warehouse stands as a potent and user-friendly data manipulation platform, offering an extensive array of tools for data ingestion, storage, transformation, and analysis. Whether you’re a novice or a seasoned data analyst, Fabric empowers you to optimize your workflow and harness the full potential of your data.

Key Differences Between ETL and ELT Processes in Azure

Azure data engineering offers two common approaches for processing data: ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform). These methods are essential for moving and processing data from source systems into data warehouses or data lakes for analysis. While both serve similar purposes, they differ in their workflows, tools, and technologies, particularly when implemented within Azure's cloud ecosystem. This article will explore the key distinctions between ETL and ELT in the context of Azure data services, helping organizations make informed decisions about their data processing strategies. Azure Data Engineer Training

1. Process Flow: Extraction, Transformation, and Loading

The most fundamental difference between ETL and ELT is the sequence in which data is processed: Microsoft Azure Data Engineer

ETL (Extract, Transform, Load):

In the ETL process, data is first extracted from source systems, transformed into the desired format or structure, and then loaded into the data warehouse or data lake.

The transformation step occurs before loading the data into the destination, ensuring that the data is cleaned, enriched, and formatted properly during the data pipeline.

ELT (Extract, Load, Transform):

ELT, on the other hand, follows a different sequence: data is extracted from the source, loaded into the destination system (e.g., a cloud data warehouse), and then transformed directly within the destination system.

The transformation happens after the data has already been stored, utilizing the computational power of the cloud infrastructure to process and modify the data.

2. Tools and Technologies in Azure

Both ETL and ELT processes require specific tools to handle data extraction, transformation, and loading. Azure provides robust tools for both approaches, but the choice of tool depends on the processing flow:

ETL in Azure:

Azure Data Factory is the primary service used for building and managing ETL pipelines. It offers a wide range of connectors for various data sources and destinations and allows for data transformations to be executed in the pipeline itself using Data Flow or Mapping Data Flows.

Azure Databricks, a Spark-based service, can also be integrated for more complex transformations during the ETL process, where heavy lifting is required for batch or streaming data processing.

ELT in Azure:

For the ELT process, Azure Synapse Analytics (formerly SQL Data Warehouse) is a leading service, leveraging the power of cloud-scale data warehouses to perform in-place transformations.

Azure Data Lake and Azure Blob Storage are used for storing raw data in ELT pipelines, with Azure Synapse Pipelines or Azure Data Factory responsible for orchestrating the load and transformation tasks.

Azure SQL Database and Azure Data Explorer are also used in ELT scenarios where data is loaded into the database first, followed by transformations using T-SQL or Azure's native query processing capabilities.

3. Performance and Scalability

The key advantage of ELT over ETL lies in its performance and scalability, particularly when dealing with large volumes of data: Azure Data Engineering Certification

ETL Performance:

ETL can be more resource-intensive because the transformation logic is executed before the data is loaded into the warehouse. This can lead to bottlenecks during the transformation step, especially if the data is complex or requires significant computation.

With Azure Data Factory, transformation logic is executed during the pipeline execution, and if there are large datasets, the process may be slower and require more manual optimization.

ELT Performance:

ELT leverages the scalable and high-performance computing power of Azure’s cloud services like Azure Synapse Analytics and Azure Data Lake. After the data is loaded into the cloud storage or data warehouse, the transformations are run in parallel using the cloud infrastructure, allowing for faster and more efficient processing.

As data sizes grow, ELT tends to perform better since the processing occurs within the cloud infrastructure, reducing the need for complex pre-processing and allowing the system to scale with the data.

4. Data Transformation Complexity

ETL Transformations:

ETL processes are better suited for complex transformations that require extensive pre-processing of data before it can be loaded into a warehouse. In scenarios where data must be cleaned, enriched, and aggregated, ETL provides a structured and controlled approach to transformations.

ELT Transformations:

ELT is more suited to scenarios where the data is already clean or requires simpler transformations that can be efficiently performed using the native capabilities of cloud platforms. Azure’s Synapse Analytics and SQL Database offer powerful querying and processing engines that can handle data transformations once the data is loaded, but this may not be ideal for very complex transformations.

5. Data Storage and Flexibility

ETL Storage:

ETL typically involves transforming the data before storage in a structured format, like a relational database or data warehouse, which makes it ideal for scenarios where data must be pre-processed or aggregated before analysis.

ELT Storage:

ELT offers greater flexibility, especially for handling raw, unstructured data in Azure Data Lake or Blob Storage. After data is loaded, transformation and analysis can take place in a more dynamic environment, enabling more agile data processing.

6. Cost Implications

ETL Costs: Azure Data Engineer Course

ETL processes tend to incur higher costs due to the additional processing power required to transform the data before loading it into the destination. Since transformations are done earlier in the pipeline, more resources (compute and memory) are required to handle these operations.

ELT Costs:

ELT typically incurs lower costs, as the heavy lifting of transformation is handled by Azure’s scalable cloud infrastructure, reducing the need for external computation resources during data ingestion. The elasticity of cloud computing allows for more cost-efficient data processing.

Conclusion

In summary, the choice between ETL and ELT in Azure largely depends on the nature of your data processing needs. ETL is preferred for more complex transformations, while ELT provides better scalability, performance, and cost-efficiency when working with large datasets. Both approaches have their place in modern data workflows, and Azure’s cloud-native tools provide the flexibility to implement either process based on your specific requirements. By understanding the key differences between these processes, organizations can make informed decisions on how to best leverage Azure's ecosystem for their data processing and analytics needs.
