👉 Data Engineering Process Fundamentals

Operational Data

Operational data is often generated by applications, and it is stored in transactional relational databases like SQL Server, Oracle and NoSQL (JSON) databases like MongoDB, Firebase. This is the data that is created after an application saves a user transaction like contact information, a purchase or other activities that are available from the application.

Features:

• Application support and transactions
• Relational data structure and SQL or document structure NoSQL
• Small queries for case analysis

Not Best For:

• Reporting system
• Large queries
• Centralized Big Data system

Data Lake - Analytical Data Staging

A Data Lake is an optimized storage system for Big Data scenarios. The primary function is to store the data in its raw format without any transformation. Analytical data is the transaction data that has been extracted from a source system via a data pipeline as part of the staging data process.

Features:

• Store the data in its raw format without any transformation
• This can include structure data like CSV files, unstructured data like JSON and XML documents, or column-base data like parquet files
• Low Cost for massive storage power
• Not Designed for querying or data analysis
• It is used as external tables by most systems

Data Warehouse - Analytical Data

A Data Warehouse is a centralized storage system that stores integrated data from multiple sources. The system is designed to host and serve Big Data scenarios with lower operational cost than transaction databases, but higher costs than a Data Lake. This system host the Analytical Data that has been processed and is ready for analytical purposes.

Data Warehouse Features:

• Stores historical data in relational tables with an optimized schema, which enables the data analysis process
• Provides SQL support to query the data
• It can integrate external resources like CSV and parquet files that are stored on Data Lakes as external tables
• The system is designed to host and serve Big Data scenarios. It is not meant to be used as a transactional system
• Storage is more expensive
• Offloads archived data to Data Lakes

Discovery - Data Analysis

During the discovery phase of a Data Engineering Process, we look to identify and clearly document a problem statement, which helps us have an understanding of what we are trying to solve. We also look at our analytical approach to make observations about at the data, its structure and source. This leads us into defining the requirements for the project, so we can define the scope, design and architecture of the solution.

• Download sample data files
• Run experiments to make observations
• Write Python scripts using VS Code or Jupyter Notebooks
• Transform the data with Pandas
• Make charts with Plotly
• Document the requirements

Design and Planning

The design and planning phase of a data engineering project is crucial for laying out the foundation of a successful system. It involves defining the system architecture, designing data pipelines, implementing source control practices, ensuring continuous integration and deployment (CI/CD), and leveraging tools like Docker and Terraform for infrastructure automation.

• Use GitHub for code repo and for CI/CD actions
• Use Terraform is an Infrastructure as Code (IaC) tool that enables us to manage cloud resources across multiple cloud providers
• Use Docker containers to run the code and manage its dependencies

Data Lake - Pipeline and Orchestration

A data pipeline is basically a workflow of tasks that can be executed in Docker containers. The execution, scheduling, managing and monitoring of the pipeline is referred to as orchestration. In order to support the operations of the pipeline and its orchestration, we need to provision a VM and data lake, and monitor cloud resources.

• This can be code-centric, leveraging languages like Python
• Or a low-code approach, utilizing tools such as Azure Data Factory, which provides a turn-key solution
• Monitor services enable us to track telemetry data
• Docker Hub, GitHub can be used for the CI/CD process

Data Warehouse - Design and Implementation

In the design phase, we lay the groundwork by defining the database system, schema model, and technology stack required to support the data warehouse’s implementation and operations. In the implementation phase, we focus on converting conceptual data models into a functional system. By creating concrete structures like dimension and fact tables and performing data transformation tasks, including data cleansing, integration, and scheduled batch loading, we ensure that raw data is processed and unified for analysis. Create a repeatable and extendable process.

Data Warehouse - Data Analysis

Data analysis is the practice of exploring data and understanding its meaning. It involves activities that can help us achieve a specific goal, such as identifying data dimensions and measures, as well as data analysis to identify outliers, trends, and distributions.

• We can accomplish these activities by writing code using Python and Pandas, SQL, Visual Studio Code or Jupyter Notebooks.
• What's more, we can use libraries, such as Plotly, to generate some visuals to further analyze data and create prototypes.

Data Analysis and Visualization

Data visualization is a powerful tool that takes the insights derived from data analysis and presents them in a visual format. While tables with numbers on a report provide raw information, visualizations allow us to grasp complex relationships and trends at a glance.

• Dashboards, in particular, bring together various visual components like charts, graphs, and scorecards into a unified interface that can help us tell a story
• Use tools like PowerBI, Looker, Tableau to model the data and create enterprise level visualizations

Conclusion

Both data lakes and data warehouses are essential components of a data engineering project. The primary function of a data lake is to store large amounts of operational data in its raw format, serving as a staging area for analytical processes. In contrast, a data warehouse acts as a centralized repository for information, enabling engineers to transform, process, and store extensive data. This allows the analytical team to utilize coding languages like Python and tools such as Jupyter Notebooks, as well as low-code platforms like Looker Studio and Power BI, to create enterprise-quality dashboards for the organization.

Presentation

What is an AI Agent?

An AI agent is a software robot that observes what’s happening, figures out what to do, and then does it—all without a human needing to guide every step.

Manufacturing Setting:

• Monitors sensor data in real time, comparing each new reading against control limits and recent patterns to detect drift, anomalies, or rule violations.
• Decides what needs to happen next—whether that’s pausing production, flagging maintenance, or adjusting inputs to keep the process stable.
• Acts without waiting for instructions, logging the event, alerting staff, or triggering automated workflows across connected systems.

"Now, you might wonder—how’s this different from just traditional automation?"

Autonomy Advantage: How AI Agents Go Beyond Automation

Unlike scripted automation, an AI agent brings autonomy—acting with awareness, judgment, and initiative. It doesn’t just execute commands—it thinks.

• Perception Observes real-time data from sensors, machines, and systems—just like a human operator watching a dashboard—but at higher speed and scale.

• Reasoning Analyzes trends and patterns from recent data (its reasoning window) to assess stability, detect anomalies, or anticipate breakdowns—just like an engineer interpreting a control chart.

• Action Takes initiative by triggering responses: adjusting inputs, alerting staff, logging events, or even halting production—without waiting for permission.

But, what powers this autonomy?

The Agent’s Secret Power

An AI agent doesn’t just automate—it senses, thinks, and acts on its own. These core technologies are what give it autonomy.

Manufacturing Setting:

• Perception Ingests real-time sensor data and stores recent readings in a reasoning window for short-term memory.
• Reasoning Uses an LLM (like Gemini) to analyze trends, detect rule violations, and interpret process behavior—beyond rigid logic.
• Action Executes commands using predefined tools via MCP—like notifying staff, triggering scripts, or calling APIs.

Wait, what are MCP tools?

Model Context Protocol (MCP): The Key to Tool Integration

MCP is a communication framework that lets AI agents use tools—like APIs, databases, or notifications—by expressing intent in structured language.

• Triggering a Notification The agent says: @notify: supervisor_alert("Vibration spike detected on motor_3A") MCP delivers a formatted message via email, SMS, or system alert.

POST /alerts/send
Content-Type: application/json

{
  "recipient": "supervisor_team",
  "message": "Vibration spike detected on motor_3A",
  "priority": "high"
}

tool: notify_supervisor
description: Sends an alert message to the assigned supervisor team
parameters:
  - name: message
    type: string
    required: true
    description: The alert message to send
example_call: "@notify: supervisor_alert(\"Vibration spike detected on motor_3A\")"
execution:
  type: webhook
  method: POST
  endpoint: https://factory.opsys.com/alerts/send
  payload_mapping:
    recipient: "supervisor_team"
    message: "{{message}}"
    priority: "high"

How Does the Agent Understand MCP?

When an agent makes a decision, it doesn’t call a function directly—it declares intent using a structured phrase. MCP translates that intent into a real-world action by matching it to a predefined tool. Essentially, reading the tool metadata as a prompt.

Agent says:

@notify: supervisor_alert("Vibration spike detected on motor_3A")

In Action:

• Agent emits intent using MCP syntax, @notify: supervisor_alert("Vibration spike detected on motor_3A")
• MCP matches the function name (supervisor_alert) to a registered tool.
• Execution Engine constructs the proper HTTP request using metadata, endpoint URL, method, headers, authentication.
• Action is performed: supervisor is notified via the external system.

The agent just describes what it needed to happen. MCP handles the how.

Benefits of MCP for AI Agents

MCP gives AI agents the flexibility and intelligence to grow beyond fixed automation—enabling them to explore, understand, and apply tools in dynamic environments.

• *Dynamic Tool Discovery:- Agents can learn about and use new tools without explicit programming.
• *Human-like Tool Usage:- Agents leverage tools based on their "understanding" of the tool's purpose and capabilities, similar to how a human learns to use a new application.
• *Enhanced Functionality & Adaptability:- Unlocks a vast ecosystem of capabilities for autonomous agents.

To act effectively, agents also need character—a defined role, a point of view, a way to think.

Shape Agent Behavior Through Prompting

Textual instructions or context provided to guide the agent's behavior and reasoning. They are crucial for controlling and directing autonomous agents.

• System Prompts Define the agent’s identity, role, tone, and reasoning strategy. This is its operating character—guiding how it thinks across all interactions. > Example: “You are a manufacturing agent that monitors vibration data and applies SPC rules to detect risk.”

• User/Agent Prompts Deliver instructions at the moment. These guide the agent’s short-term focus and task-specific reasoning. > Example: “Analyze this new sample and let me know if we’re trending toward a shutdown.”

How do I get started?

Getting Started with AI Agents: The Tech Stack

To build your first AI agent, these tools offer a powerful foundation—though not the only options, they represent a well-integrated, production-ready ecosystem:

• LangChain: Core framework for integrating tools, memory, vector databases, and APIs. Think of it as the foundation that gives your agent capabilities.

• LangGraph Adds orchestration and state management by turning your LangChain components into reactive, stateful workflows—ideal for agents that need long-term memory and conditional behavior.

• LangSmith: Monitoring and evaluation suite to observe, debug, and improve your agents—see how prompts, memory, and tools interact across sessions.

• n8n: No-code orchestration platform that lets you deploy agents into real-world business systems—perfect for automation without touching code.

• Action Takes initiative by triggering responses: adjusting inputs, alerting staff, logging events, or even halting production—without waiting for permission.

But, what powers this autonomy?

The Agent’s Secret Power

An AI agent doesn’t just automate—it senses, thinks, and acts on its own. These core technologies are what give it autonomy.

Manufacturing Setting:

• Perception Ingests real-time sensor data and stores recent readings in a reasoning window for short-term memory.
• Reasoning Uses an LLM (like Gemini) to analyze trends, detect rule violations, and interpret process behavior—beyond rigid logic.
• Action Executes commands using predefined tools via MCP—like notifying staff, triggering scripts, or calling APIs.

Wait, what are MCP tools?

Model Context Protocol (MCP): The Key to Tool Integration

MCP is a communication framework that lets AI agents use tools—like APIs, databases, or notifications—by expressing intent in structured language.

• Triggering a Notification The agent says: @notify: supervisor_alert("Vibration spike detected on motor_3A") MCP delivers a formatted message via email, SMS, or system alert.

POST /alerts/send
Content-Type: application/json

{
  "recipient": "supervisor_team",
  "message": "Vibration spike detected on motor_3A",
  "priority": "high"
}

tool: notify_supervisor
description: Sends an alert message to the assigned supervisor team
parameters:
  - name: message
    type: string
    required: true
    description: The alert message to send
example_call: "@notify: supervisor_alert(\"Vibration spike detected on motor_3A\")"
execution:
  type: webhook
  method: POST
  endpoint: https://factory.opsys.com/alerts/send
  payload_mapping:
    recipient: "supervisor_team"
    message: "{{message}}"
    priority: "high"

How Does the Agent Understand MCP?

When an agent makes a decision, it doesn’t call a function directly—it declares intent using a structured phrase. MCP translates that intent into a real-world action by matching it to a predefined tool. Essentially, reading the tool metadata as a prompt.

Agent says:

@notify: supervisor_alert("Vibration spike detected on motor_3A")

In Action:

• Agent emits intent using MCP syntax, @notify: supervisor_alert("Vibration spike detected on motor_3A")
• MCP matches the function name (supervisor_alert) to a registered tool.
• Execution Engine constructs the proper HTTP request using metadata, endpoint URL, method, headers, authentication.
• Action is performed: supervisor is notified via the external system.

The agent just describes what it needed to happen. MCP handles the how.

Benefits of MCP for AI Agents

MCP gives AI agents the flexibility and intelligence to grow beyond fixed automation—enabling them to explore, understand, and apply tools in dynamic environments.

• *Dynamic Tool Discovery:- Agents can learn about and use new tools without explicit programming.
• *Human-like Tool Usage:- Agents leverage tools based on their "understanding" of the tool's purpose and capabilities, similar to how a human learns to use a new application.
• *Enhanced Functionality & Adaptability:- Unlocks a vast ecosystem of capabilities for autonomous agents.

To act effectively, agents also need character—a defined role, a point of view, a way to think.

Shape Agent Behavior Through Prompting

Textual instructions or context provided to guide the agent's behavior and reasoning. They are crucial for controlling and directing autonomous agents.

• System Prompts Define the agent’s identity, role, tone, and reasoning strategy. This is its operating character—guiding how it thinks across all interactions. > Example: “You are a manufacturing agent that monitors vibration data and applies SPC rules to detect risk.”

• User/Agent Prompts Deliver instructions at the moment. These guide the agent’s short-term focus and task-specific reasoning. > Example: “Analyze this new sample and let me know if we’re trending toward a shutdown.”
