Data Engineer vs Software Engineer
‍

Hey there, fellow data engineers,

So, I was chatting with a friend the other day, and they asked me, "Why aren't data engineers considered the same as software engineers?" And I was like, "Dude, excellent question!" It got me thinking about how our profession is often undervalued and misunderstood, and I decided it was time to set the record straight. So, buckle up, because we're about to dive into some serious misconceptions and discuss ways organizations can achieve parity between data engineers and software engineers.

First off, let's clear the air on this age-old debate. Albert Einstein once said, "Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid." Likewise, if you compare data engineers to software engineers based on their coding skills alone, you're missing the big picture.

Data engineers are masters of data manipulation, optimization, and management. We build the foundations for data-driven decision-making in businesses, and that's no small feat. It's true, we're not software engineers, but our skills are just as valuable, and in some cases, even more critical to an organization's success.

In recent years, the data engineering field has made remarkable strides. Data engineers now have a wealth of powerful tools and technologies at their disposal. From building complex data pipelines to designing state-of-the-art machine learning models, we've achieved a lot, and it's time for organizations to recognize that.

Just take a look at the testimonials from those who have witnessed the impact of data engineering on their products:

Arzumy, Chief Technology Officer at Fave, said, "Our data engineering team played a crucial role in optimizing the performance of our platform. Their expertise in data processing and management helped us reduce latency, enhance user experience, and ultimately, drive growth."

Chandan Singh, Product Head at Adda247 Inc, shared, "The collaboration between our data engineers and software engineers has been invaluable in delivering a robust and scalable product. The data engineers' ability to work with massive datasets and build efficient data pipelines has been a game-changer for our business."

One notable example of data engineering's immense impact is the development of ChatGPT by OpenAI. Data engineers were instrumental in creating the sophisticated architecture that allows the model to understand and generate human-like text. They designed and managed the data pipelines that fed the model with vast amounts of text data, enabling it to learn and improve over time.

Now that we've established the importance of data engineers let's talk about how organizations can close the gap and ensure data engineers receive the same respect and recognition as software engineers. Here are some steps that organizations can take:

  1. Educate stakeholders on the role of data engineers: The first step to achieving parity is by ensuring that everyone in the organization understands the value of data engineering. A simple way to do this is by hosting workshops or training sessions that highlight the importance of data engineering and its impact on the business.
  2. Encourage cross-functional collaboration: The more we collaborate with our software engineering counterparts, the more likely we are to be seen as equals. By working together on projects, data engineers and software engineers can learn from one another and appreciate each other's skills.
  3. Develop clear career progression paths: Just like software engineers, data engineers need to have clear career progression paths to grow and thrive in their roles. This means setting up mentorship programs, offering opportunities for professional development, and providing regular performance feedback.
  4. Foster an inclusive culture: A company culture that values diversity and inclusion is critical for both data engineers and software engineers to succeed. By fostering a culture that embraces different skill sets and perspectives, organizations can empower their employees and create a more balanced and equitable workplace.
  1. Recognize and celebrate success: Don't forget to celebrate the wins! By recognizing the achievements of data engineers, organizations can help boost morale and encourage further innovation in the field.
  2. Invest in data engineering tools and resources: It's essential for organizations to invest in the right tools and resources that enable data engineers to do their job effectively. This includes providing access to cutting-edge technologies and software, as well as maintaining up-to-date training programs.

High-level comparison between Data Engineers and Software Engineers (little biased towards DE):

In conclusion, it's high time that we put the "Data Engineers vs. Software Engineers" debate to rest. We're all in this together, and we should be working towards creating an inclusive and supportive environment where both data engineers and software engineers can thrive.

As Ada Lovelace, a pioneering computer scientist, once said, "The more we understand what is going on, the more we can see there is no one easy-to-define structure called 'the future.'

‍

It is a set of possibilities, a set of alternative roads that lead to different destinations." The future of technology depends on our ability to recognize the unique strengths and contributions of each profession, including data engineers and software engineers.

We must embrace the reality that data engineering is not a second-rate version of software engineering, but a field with its own unique challenges and triumphs. Organizations that champion their data engineers, invest in their growth, and foster an environment where both data engineers and software engineers can thrive will undoubtedly reap the rewards of a data-driven future.

So, my fellow data engineers, let's band together and work towards breaking down the stereotypes that have held us back for too long. We've already made tremendous strides in the past few years, and it's time to show the world what we're truly capable of. Remember, we're all in this together, and we're just as deserving of recognition and respect as our software engineering counterparts.

To my fellow data engineers out there: keep pushing boundaries, challenging the status quo, and showcasing your incredible talents. With hard work, dedication, and a little bit of solidarity, we can transform the perception of data engineering and achieve the parity we rightfully deserve.

What is a Data Trust Platform in financial services?
A Data Trust Platform is a unified framework that combines data observability, governance, lineage, and cataloging to ensure financial institutions have accurate, secure, and compliant data. In banking, it enables faster regulatory reporting, safer AI adoption, and new revenue opportunities from data products and APIs.
Why do AI initiatives fail in Latin American banks and fintechs?
Most AI initiatives in LATAM fail due to poor data quality, fragmented architectures, and lack of governance. When AI models are fed stale or incomplete data, predictions become inaccurate and untrustworthy. Establishing a Data Trust Strategy ensures models receive fresh, auditable, and high-quality data, significantly reducing failure rates.
What are the biggest data challenges for financial institutions in LATAM?
Key challenges include: Data silos and fragmentation across legacy and cloud systems. Stale and inconsistent data, leading to poor decision-making. Complex compliance requirements from regulators like CNBV, BCB, and SFC. Security and privacy risks in rapidly digitizing markets. AI adoption bottlenecks due to ungoverned data pipelines.
How can banks and fintechs monetize trusted data?
Once data is governed and AI-ready, institutions can: Reduce OPEX with predictive intelligence. Offer hyper-personalized products like ESG loans or SME financing. Launch data-as-a-product (DaaP) initiatives with anonymized, compliant data. Build API-driven ecosystems with partners and B2B customers.
What is data dictionary example?
A data dictionary is a centralized repository that provides detailed information about the data within an organization. It defines each data element—such as tables, columns, fields, metrics, and relationships—along with its meaning, format, source, and usage rules. Think of it as the “glossary” of your data landscape. By documenting metadata in a structured way, a data dictionary helps ensure consistency, reduces misinterpretation, and improves collaboration between business and technical teams. For example, when multiple teams use the term “customer ID”, the dictionary clarifies exactly how it is defined, where it is stored, and how it should be used. Modern platforms like Decube extend the concept of a data dictionary by connecting it directly with lineage, quality checks, and governance—so it’s not just documentation, but an active part of ensuring data trust across the enterprise.
What is an MCP Server?
An MCP Server stands for Model Context Protocol Server—a lightweight service that securely exposes tools, data, or functionality to AI systems (MCP clients) via a standardized protocol. It enables LLMs and agents to access external resources (like files, tools, or APIs) without custom integration for each one. Think of it as the “USB-C port for AI integrations.”
How does MCP architecture work?
The MCP architecture operates under a client-server model: MCP Host: The AI application (e.g., Claude Desktop or VS Code). MCP Client: Connects the host to the MCP Server. MCP Server: Exposes context or tools (e.g., file browsing, database access). These components communicate over JSON‑RPC (via stdio or HTTP), facilitating discovery, execution, and contextual handoffs.
Why does the MCP Server matter in AI workflows?
MCP simplifies access to data and tools, enabling modular, interoperable, and scalable AI systems. It eliminates repetitive, brittle integrations and accelerates tool interoperability.
How is MCP different from Retrieval-Augmented Generation (RAG)?
Unlike RAG—which retrieves documents for LLM consumption—MCP enables live, interactive tool execution and context exchange between agents and external systems. It’s more dynamic, bidirectional, and context-aware.
What is a data dictionary?
A data dictionary is a centralized repository that provides detailed information about the data within an organization. It defines each data element—such as tables, columns, fields, metrics, and relationships—along with its meaning, format, source, and usage rules. Think of it as the “glossary” of your data landscape. By documenting metadata in a structured way, a data dictionary helps ensure consistency, reduces misinterpretation, and improves collaboration between business and technical teams. For example, when multiple teams use the term “customer ID”, the dictionary clarifies exactly how it is defined, where it is stored, and how it should be used. Modern platforms like Decube extend the concept of a data dictionary by connecting it directly with lineage, quality checks, and governance—so it’s not just documentation, but an active part of ensuring data trust across the enterprise.
What is the purpose of a data dictionary?
The primary purpose of a data dictionary is to help data teams understand and use data assets effectively. It provides a centralized repository of information about the data, including its meaning, origins, usage, and format, which helps in planning, controlling, and evaluating the collection, storage, and use of data.
What are some best practices for data dictionary management?
Best practices for data dictionary management include assigning ownership of the document, involving key stakeholders in defining and documenting terms and definitions, encouraging collaboration and communication among team members, and regularly reviewing and updating the data dictionary to reflect any changes in data elements or relationships.
How does a business glossary differ from a data dictionary?
A business glossary covers business terminology and concepts for an entire organization, ensuring consistency in business terms and definitions. It is a prerequisite for data governance and should be established before building a data dictionary. While a data dictionary focuses on technical metadata and data objects, a business glossary provides a common vocabulary for discussing data.
What is the difference between a data catalog and a data dictionary?
While a data catalog focuses on indexing, inventorying, and classifying data assets across multiple sources, a data dictionary provides specific details about data elements within those assets. Data catalogs often integrate data dictionaries to provide rich context and offer features like data lineage, data observability, and collaboration.
What challenges do organizations face in implementing data governance?
Common challenges include resistance from business teams, lack of clear ownership, siloed systems, and tool fragmentation. Many organizations also struggle to balance strict governance with data democratization. The right approach involves embedding governance into workflows and using platforms that unify governance, observability, and catalog capabilities.
How does data governance impact AI and machine learning projects?
AI and ML rely on high-quality, unbiased, and compliant data. Poorly governed data leads to unreliable predictions and regulatory risks. A governance framework ensures that data feeding AI models is trustworthy, well-documented, and traceable. This increases confidence in AI outputs and makes enterprises audit-ready when regulations apply.
What is data governance and why is it important?
Data governance is the framework of policies, ownership, and controls that ensure data is accurate, secure, and compliant. It assigns accountability to data owners, enforces standards, and ensures consistency across the organization. Strong governance not only reduces compliance risks but also builds trust in data for AI and analytics initiatives.
What is the difference between a data catalog and metadata management?
A data catalog is a user-facing tool that provides a searchable inventory of data assets, enriched with business context such as ownership, lineage, and quality. It’s designed to help users easily discover, understand, and trust data across the organization. Metadata management, on the other hand, is the broader discipline of collecting, storing, and maintaining metadata (technical, business, and operational). It involves defining standards, policies, and processes for metadata to ensure consistency and governance. In short, metadata management is the foundation—it structures and governs metadata—while a data catalog is the application layer that makes this metadata accessible and actionable for business and technical users.
What features should you look for in a modern data catalog?
A strong catalog includes metadata harvesting, search and discovery, lineage visualization, business glossary integration, access controls, and collaboration features like data ratings or comments. More advanced catalogs integrate with observability platforms, enabling teams to not only find data but also understand its quality and reliability.
Why do businesses need a data catalog?
Without a catalog, employees often struggle to find the right datasets or waste time duplicating efforts. A data catalog solves this by centralizing metadata, providing business context, and improving collaboration. It enhances productivity, accelerates analytics projects, reduces compliance risks, and enables data democratization across teams.
What is a data catalog and how does it work?
A data catalog is a centralized inventory that organizes metadata about data assets, making them searchable and easy to understand. It typically extracts metadata automatically from various sources like databases, warehouses, and BI tools. Users can then discover datasets, understand their lineage, and see how they’re used across the organization.
What are the key features of a data observability platform?
Modern platforms include anomaly detection, schema and freshness monitoring, end-to-end lineage visualization, and alerting systems. Some also integrate with business glossaries, support SLA monitoring, and automate root cause analysis. Together, these features provide a holistic view of both technical data pipelines and business data quality.
How is data observability different from data monitoring?
Monitoring typically tracks system metrics (like CPU usage or uptime), whereas observability provides deep visibility into how data behaves across systems. Observability answers not only “is something wrong?” but also “why did it go wrong?” and “how does it impact downstream consumers?” This makes it a foundational practice for building AI-ready, trustworthy data systems.
What are the key pillars of Data Observability?
The five common pillars include: Freshness, Volume, Schema, Lineage, and Quality. Together, they provide a 360° view of how data flows and where issues might occur.
What is Data Observability and why is it important?
Data observability is the practice of continuously monitoring, tracking, and understanding the health of your data systems. It goes beyond simple monitoring by giving visibility into data freshness, schema changes, anomalies, and lineage. This helps organizations quickly detect and resolve issues before they impact analytics or AI models. For enterprises, data observability builds trust in data pipelines, ensuring decisions are made with reliable and accurate information.
