Front-end Website Programming Languages

The following programming languages are a must when it comes to website development.

HTML

HTML is the standard and base-level programming language used to create every web page. It's used for structuring content. HTML, on its own, would make a very boring-looking website in black and white.

CSS

CSS is a programming language that is used to style HTML web pages. It specifies how HTML should look on various screens.

JavaScript

JavaScript is a powerful front-end programming language used to add functionality to a web page once it's loaded on the screen. It's used for calculations, special effects and changing elements dynamically on the fly.

Back-end Website Programming Languages

There are numerous back-end programming languages that could be used in website development. The following two are the most common back-end languages that MarkIT Space uses to program websites and powerful website applications.

PHP

PHP is a powerful back-end programming language, which means the code is executed on its web server before the result is displayed on the screen for the user to see. It's often used to submit form data to a database or send emails. It's also used to save login credentials and create cookies for a local computer to remember specific details.

In the fast-moving world of 2026, where Generative AI and automated machine learning have become the headlines of every technology journal, a quiet but powerful realisation has dawned upon the global data community. Despite the meteoric rise of natural language processing and AI-driven code generation, the foundational language of data—SQL—remains the most critical skill for any aspiring professional. For eight consecutive years, as reported by Indeed 2025 and 2026 data, SQL has remained the most requested skill in data-related job postings, outperforming Python, R, and even specialised AI competencies.

The data analytics landscape is often viewed through the lens of the latest shiny tool, yet 73 percent of Fortune 500 data teams use SQL daily to drive their decision-making processes. For a student looking to enrol in a Data Analytics Course, understanding why this forty-year-old language still dominates the industry is essential for long-term career success. This article explores the 2026 evidence that cements SQL as the backbone of the industry and explains why an Imarticus Data Analytics Program focuses so heavily on this enduring skill.

The 2026 Data Reality: Why the Death of SQL was a Myth

A few years ago, many predicted that NoSQL databases and AI-driven interfaces would render SQL obsolete. The narrative suggested that we would soon be talking to our data in plain English, making the need to write Structured Query Language unnecessary. However, the realisation of 2026 is that AI does not replace SQL; it relies on it.

Natural language interfaces that allow users to ask questions like "What were our sales in Mumbai last quarter?" actually work by translating that English sentence into a complex SQL query. For a Data Analyst to verify, debug, or optimise these AI-generated queries, a deep understanding of SQL is more important than ever. If you cannot read the code the AI produces, you cannot trust the insights it delivers. This is why every modern Data Analyst Course must prioritise SQL as a core competency.

The Structural Dominance of SQL in Corporate India

India's corporate sector, particularly the BFSI (Banking, Financial Services, and Insurance) and retail sectors, is built on relational databases. Whether it is a legacy bank in Mumbai or a high-tech e-commerce startup in Bangalore, the data resides in SQL-based systems like PostgreSQL, MySQL, SQL Server, or modern cloud warehouses like Snowflake and BigQuery.

Indeed, 2025 and 2026 job trends show that while many companies are experimenting with AI, their core operations still run on SQL. A Data Science Course that ignores this reality is doing its students a disservice. Imarticus understands this industrial requirement, ensuring that its curriculum reflects the actual daily tasks of a working professional in the Indian market.

Why Every Data Analytics Course Must Be SQL First

If you are looking at a Data Analytics Program in 2026, the depth of its SQL module is a litmus test for its quality. A surface-level introduction is no longer enough. The industry requires professionals who can perform complex data engineering and analysis directly within the database.

Data Governance and the DPDP Act With the full implementation of the Digital Personal Data Protection (DPDP) Act in India, how data is accessed and queried has become a legal concern. SQL is the primary tool used to implement data masking, row-level security, and audit trails. Imarticus doesn't just teach you how to build a model; it teaches you how to build a compliant model. The curriculum includes modules on how SQL interacts with the DPDP Act and international standards like GDPR, ensuring you have a global perspective on privacy and data security.

The Speed of Insight In 2026, the volume of data is so massive that moving it from a database to a tool like Python for analysis is often too slow and expensive. The modern approach is to do the heavy lifting inside the database using SQL. This "In Database Analytics" requires mastery of advanced SQL techniques like Window Functions, Common Table Expressions (CTEs), and complex joins. A Data Analyst Course that doesn't master these topics is not preparing its students for the scale of 2026 data.

Integration with Visualisation Tools Tools like Tableau and Power BI are essential for a Data Analyst, but their performance depends entirely on the efficiency of the underlying SQL queries. According to the Stack Overflow Developer Survey 2025, professionals who can write optimised SQL for their dashboards are 40 percent more productive. Imarticus focuses on this synergy, teaching students how to bridge the gap between back-end data extraction and front-end visualisation.

The Role of SQL in the Life of a 2026 Data Scientist

While a Data Scientist is often associated with building complex machine learning models in Python, the professional realisation for most is that 80 percent of their time is spent on data preparation. In 2026, this data preparation happens in SQL.

Whether you are building a recommendation engine or a churn prediction model, the initial feature engineering—the process of selecting and transforming variables—is done using SQL. A Data Science Program that focuses only on the algorithms without teaching the data retrieval layer leaves its graduates stranded when they enter a real-world production environment. Imarticus addresses this by integrating SQL into every stage of its Data Science Course, from initial exploration to final model deployment.

SQL for Non-Technical Professionals: The Democratisation of Data

One of the most interesting trends in 2026 is the number of professionals from marketing, HR, and operations who are enrolling in a Data Analyst Program to learn SQL. They have realised that being able to query their own data, rather than waiting for the IT department, gives them a massive competitive advantage.

For an HR manager in Delhi or a marketing lead in Pune, SQL is the "superpower" that allows them to prove their impact with hard numbers. Imarticus caters to this demographic by providing an intuitive, business case study approach to SQL. Imarticus doesn't just teach syntax; it teaches how to answer business questions using data.

The Imarticus SQL Curriculum: A Deep Dive into Practical Excellence

Imarticus has established itself as a leader in data education by staying ahead of industry trends. The SQL module within the Imarticus Data Analytics Course is designed to be the most comprehensive in the market.

Hands-on Labs and Real World Datasets Imarticus provides students with access to massive, messy datasets that mirror the reality of the 2026 corporate world. Students don't just learn "SELECT ALL"; they learn how to clean inconsistent data, handle null values, and join tables from different business units.

Business Logic and Problem Solving The Imarticus Data Analytics Program uses a case study method. For example, students might be tasked with identifying the most valuable customers for a bank using SQL. This involves writing complex queries that calculate Recency, Frequency, and Monetary (RFM) values—a standard task in the BFSI sector.

Performance Tuning and Optimisation In 2026, writing a query that works is not enough; it must be fast. Imarticus teaches the nuances of indexing, execution plans, and query optimisation. This technical depth is what allows Imarticus alumni to stand out in technical interviews at top-tier firms.

The Realisation of Career Growth with SQL

The financial realisation of mastering SQL is significant. In 2026, the salary premium for a Data Analyst who is proficient in SQL is approximately 20 to 30 percent higher than that of those who only know basic visualisation tools. According to Indeed 2025 data, job roles like "SQL Developer," "Data Engineer," and "Database Analyst" are among the most stable and well-paid positions in the Indian tech economy.

By completing an Imarticus Data Science Program, students position themselves for these high-growth roles. The course provides the technical foundation, but also the placement support needed to enter the market with confidence. Imarticus has built deep relationships with India's leading corporations, ensuring that the SQL skills taught in the classroom are exactly what hiring managers are looking for.

SQL and the Future of AI: A Symbiotic Relationship

As we look toward the end of the decade, the relationship between SQL and AI will only strengthen. We are seeing the rise of "Vector Databases" and "Graph Databases," but even these specialised systems are adopting SQL-like interfaces to make them accessible to the global workforce.

A Data Analyst Course in 2026 must prepare students for this hybrid future. You will use AI to write the first draft of your SQL, but you will use your expertise to ensure it is accurate, efficient, and compliant with laws like the DPDP Act. This is the "Human in the Loop" model that defines 2026. Imarticus is at the forefront of this evolution, teaching students how to use AI as a co-pilot for their SQL development.

Case Studies: SQL in Action Across Indian Hubs

To understand the geographic impact, let us look at how SQL is used in different Indian cities in 2026.

Mumbai: The Financial Hub In Mumbai, SQL is used to manage millions of banking transactions. A Data Analyst in a Mumbai bank uses SQL to detect fraud by identifying unusual patterns in transaction data. The Imarticus Data Analytics Course uses BFSI-specific case studies to prepare students for these high-stakes roles.

Bangalore: The Tech Capital In Bangalore, e-commerce giants use SQL to manage their supply chains. Analysts write queries to optimise delivery routes and manage inventory levels in real time. The Imarticus Data Analyst Program focuses on the scale and speed required by these tech giants.

Delhi NCR: The Corporate Center In Delhi and Gurugram, SQL is the tool for corporate strategy. Analysts use it to merge data from different departments to create a "Single Source of Truth" for the company’s leadership. Imarticus prepares students for these strategic roles by focusing on data warehousing and ETL (Extract, Transform, Load) processes.

Why Python Alone is Not Enough

A common mistake made by many beginners is focusing exclusively on Python. While Python is brilliant for machine learning and automation, it is not a database language. In a real-world production environment, you cannot use Python until you have first used SQL to get the data out of the system.

A balanced Data Science Course must treat SQL and Python as equal partners. One gets the data, and the other builds the model. Imarticus ensures this balance, providing a holistic education that covers the entire data lifecycle. Imarticus doesn't just teach you one tool; it teaches you the entire ecosystem of modern data analytics.

SQL JOINs are where things get interesting.

INNER JOIN gives you matches. LEFT JOIN keeps everything from the left. RIGHT JOIN does the opposite. FULL OUTER JOIN? No data left behind.

Same tables. Different logic. Different outcomes.

Understanding JOINs isn’t just syntax — it’s learning how relationships in data actually work.

Data has stories. SQL joins decide which ones get told.

INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN—four quiet operators that shape how information connects, disappears, or finally shows up. When you understand joins, tables stop being rows and columns and start becoming conversations between data.

This visual breaks down the logic in a way that feels less like memorizing syntax and more like understanding intent. Perfect for learners, late-night revisions, and anyone trying to make peace with SQL.
