If you’re new to Databricks, chances are someone told you “Everything starts with a Notebook.” They weren’t wrong. In Databricks, a Notebook is where your entire data engineering workflow begins from reading raw data, transforming it, visualizing trends, and even deploying jobs. It’s your coding lab, dashboard, and documentation space all in one. What Is a Databricks Notebook? A Databricks Notebook is an interactive environment that supports multiple programming languages such as Python, SQL, R, and Scala. Each Notebook is divided into cells you can write code, add text (Markdown), and visualize data directly within it. Unlike local scripts, Notebooks in Databricks run on distributed Spark clusters. That means even your 100 GB dataset is processed within seconds using parallel computation. So, Notebooks are more than just code editors they are collaborative data workspaces for building, testing, and documenting pipelines. How Databricks Notebooks Work Under the hood, every Notebook connects to a cluster a group of virtual machines managed by Databricks. When you run code in a cell, it’s sent to Spark running on the cluster, processed there, and results are sent back to your Notebook. This gives you the scalability of big data without worrying about servers or configurations. Setting Up Your First Cluster Before running a Notebook, you must create a cluster it’s like starting the engine of your car. Here’s how: Step-by-Step: Creating a Cluster in a Standard Databricks Workspace Once the cluster is active, you’ll see a green light next to its name now it’s ready to process your code. Creating Your First Notebook Now, let’s build your first Databricks Notebook: Your Notebook is now live ready to connect to data and start executing. Loading and Exploring Data Let’s say you have a sales dataset in Azure Blob Storage or Data Lake. You can easily read it into Databricks using Spark: df = spark.read.csv(“/mnt/data/sales_data.csv”, header=True, inferSchema=True)display(df.limit(5)) Databricks automatically recognizes your file’s schema and displays a tabular preview.Now, you can transform the data: from pyspark.sql.functions import col, sumsummary = df.groupBy(“Region”).agg(sum(“Revenue”).alias(“Total_Revenue”))display(summary) Or, switch to SQL instantly: %sqlSELECT Region, SUM(Revenue) AS Total_RevenueFROM sales_dataGROUP BY RegionORDER BY Total_Revenue DESC Visualizing DataDatabricks Notebooks include built-in charting tools.After running your SQL query:Click + → Visualization → choose Bar Chart.Assign Region to the X-axis and Total_Revenue to the Y-axis.Congratulations — you’ve just built your first mini-dashboard! Real-World Example: ETL Pipeline in a Notebook In many projects, Databricks Notebooks are used to build ETL pipelines: Each stage is often written in a separate cell, making debugging and testing easier.Once tested, you can schedule the Notebook as a Job running daily, weekly, or on demand. Best Practices To conclude, Databricks Notebooks are not just a beginner’s playground they’re the backbone of real data engineering in the cloud.They combine flexibility, scalability, and collaboration into a single workspace where ideas turn into production pipelines. If you’re starting your data journey, learning Notebooks is the best first step.They help you understand data movement, Spark transformations, and the Databricks workflow everything a data engineer need.

Managing and processing large datasets efficiently is a key requirement in modern data engineering. Azure Databricks, an optimized Apache Spark-based analytics platform, provides a seamless way to handle such workflows. This blog will explore how PySpark and SQL can be combined to dynamically process, and clean data using the medallion architecture (Only Raw → Silver) and store the results in Azure Blob Storage as PDFs. Understanding the Medallion Architecture: – The medallion architecture follows a structured approach to data transformation: Aggregated Layer (Gold): Optimized for analytics, reports, and machine learning. In our use case, we extract raw tables from Databricks, clean them dynamically, and store the refined data into the silver schema. Key technologies / dependencies used: – Step-by-Step Code Breakdown 1. Setting Up the Environment Install & import necessary libraries The above command installs reportlab, which is used to generate PDFs. This imports essential libraries for data handling, visualization, and storage. 2. Connecting to Azure Blob Storage This snippet authenticates the Databricks notebook with Azure Blob Storage and prepares a connection to upload the final PDFs; Initiates the Spark Session as well. 3. Cleaning Data: Raw to Silver Layer Fetch all raw tables This dynamically removes NULL values from raw data and creates a cleaned table in the silver layer. 4. Verifying and comparing the Raw and the Cleaned (Silver) 4. Converting Cleaned Data to PDFs 5. Converting Cleaned Data to PDFs Output at the Azure Storage Container This process reads cleaned tables, converts them into PDFs with structured formatting, and uploads them to Azure Blob Storage. 6. Automating cleaning at Databricks at fixed scheduleThis is automated by scheduling the notebook & it’s associated compute instance to run at fixed intervals and timestamps. Further actions: – Why Store Data in Azure Blob Storage? To conclude, by leveraging Databricks, PySpark, SQL, ReportLab, and Azure Blob Storage, we have automated the pipeline from raw data ingestion to cleaned and formatted PDF reports. This approach ensures: a. Efficient data cleansing using SQL queries dynamically. b. Structured data transformation within the medallion architecture. c. Seamless storage and accessibility through Azure Blob Storage. This methodology can be extended to include Gold Layer processing for advanced analytics and reporting.

Introduction: Two Powerful Tools, One Common Question If you work in data engineering, you’ve probably faced this question:Should I use Azure Data Factory or Databricks for my ETL pipeline? Both tools can move and transform data, but they serve very different purposes.Understanding where each tool fits can help you design cleaner, faster, and more cost-effective data pipelines. Let’s explore how these two Azure services complement each other rather than compete. What Is Azure Data Factory (ADF) Azure Data Factory is a data orchestration service.It’s designed to move, schedule, and automate data workflows between systems. Think of ADF as the “conductor of your data orchestra” — it doesn’t play the instruments itself, but it ensures everything runs in sync. Key Capabilities of ADF: Best For: What Is Azure Databricks Azure Databricks is a data processing and analytics platform built on Apache Spark.It’s designed for complex transformations, data modeling, and machine learning on large-scale data. Think of Databricks as the “engine” that processes and transforms the data your ADF pipelines deliver. Key Capabilities of Databricks: Best For: ADF vs Databricks: A Detailed Comparison Feature Azure Data Factory (ADF) Azure Databricks Primary Purpose Orchestration and data movement Data processing and advanced transformations Core Engine Integration Runtime Apache Spark Interface Type Low-code (GUI-based) Code-based (Python, SQL, Scala) Performance Limited by Data Flow engine Distributed and scalable Spark clusters Transformations Basic mapping and joins Complex joins, ML models, and aggregations Data Handling Batch-based Batch and streaming Cost Model Pay per pipeline run and Data Flow activity Pay per cluster usage (compute time) Versioning and Debugging Visual monitoring and alerts Notebook history and logging Integration Best for orchestrating multiple systems Best for building scalable ETL within pipelines In simple terms, ADF moves the data, while Databricks transforms it deeply. When to Use ADF Use Azure Data Factory when: Example:Copying data daily from Salesforce and SQL Server into Azure Data Lake. When to Use Databricks Use Databricks when: Example:Transforming millions of sales records into curated Delta tables with customer segmentation logic. When to Use Both Together In most enterprise data platforms, ADF and Databricks work together. Typical Flow: This hybrid approach combines the automation of ADF with the computing power of Databricks. Example Architecture:ADF → Databricks → Delta Lake → Synapse → Power BI This is a standard enterprise pattern for modern data engineering. Cost Considerations Using ADF for orchestration and Databricks for processing ensures you only pay for what you need. Best Practices Azure Data Factory and Azure Databricks are not competitors.They are complementary tools that together form a complete ETL solution. Understanding their strengths helps you design data pipelines that are reliable, scalable, and cost-efficient.

Most reporting problems do not come from Power BI or visualization tools. They come from how the data is organized before it reaches the reporting layer. A lot of teams try to push raw CRM tables, ERP extracts, finance dumps, and timesheet files directly into Power BI models. This usually leads to slow refreshes, constant model changes, broken relationships, and inconsistent metrics across teams. A clean Medallion Architecture solves these issues by giving your data a predictable, layered structure inside Databricks. It gives reporting teams clarity, improves performance, and reduces rework across projects. Below is a senior-level view of how to design and implement it in a way that supports long-term reporting needs. Why the Medallion Architecture Matters The Medallion model gets discussed often, but in practice the value comes from discipline and consistency. The real benefit is not the three layers. It is the separation of responsibilities: This separation ensures data engineers, analysts, and reporting teams do not step on each other’s work. You avoid the common trap of mixing raw, cleaned, and aggregated data in the same folder or the same table, which eventually turns the lake into a “large folder with files,” not a structured ecosystem. Bronze Layer: The Record of What Actually Arrived The Bronze layer should be the most predictable part of your data platform. It contains raw data as received from CRM, ERP, HR, finance, or external systems. From a senior perspective, the bronze layer has two primary responsibilities: This means storing load timestamps, file names, and source identifiers. The Bronze layer is not the place for business logic. Any adjustment here will compromise traceability. A good bronze table lets you answer questions like:“What exactly did we receive from Business Central on the 7th of this month?”If your Bronze layer cannot answer this, it needs improvement. Silver Layer: Apply Business Logic Once, Use It Everywhere The Silver layer transforms raw data into standardized, trusted datasets. A senior approach focuses on solving root issues here, not patching them later.Typical responsibilities include: This is where you remove all the “noise” that Power BI models should never see. Silver is also where cross-functional logic goes.For example: Once the Silver layer is stable, the Gold layer becomes significantly simpler. Gold Layer: Data Structured for Reporting and Performance (Gold) represents the presentation layer of the Lakehouse. It contains curated datasets designed around reporting and analytics use cases, rather than reflecting how data is stored in source systems. A senior-level Gold layer focuses on: Gold tables should reflect business definitions, not technical ones. If your teams rely on metrics like utilization, revenue recognition, resource cost rates, or customer lifetime value, those calculations should live here. Gold is also where performance tuning matters. Partitioning, Z-ordering, and optimizing Delta tables significantly improves refresh times and Power BI performance. A Real-World Example In projects where CRM, Finance, HR, and Project data come from different systems, reporting becomes difficult when each department pulls data separately. A Medallion architecture simplifies this: The reporting team consumes these gold tables directly in Power BI with minimal transformations. Why This Architecture Works for Reporting Teams To conclude, a clean Medallion Architecture is not about technology – it’s about structure, discipline, and clarity. When implemented well, it removes daily friction between engineering and reporting teams.It also creates a strong foundation for governance, performance, and future scalability. Databricks makes the Medallion approach easier to maintain, especially when paired with Delta Lake and Unity Catalog. Together, these pieces create a data platform that can support both operational reporting and executive analytics at scale.

The fastest way to lose control of enterprise data? Managing governance separately across workspaces. Unity Catalog solves this with one centralized layer for security, lineage, and discovery. Data governance is crucial for any organization looking to manage and secure its data assets effectively. Databricks’ Unity Catalog is a centralized solution that provides a unified interface for managing access control, auditing, data lineage, and discovery. This blog will guide you through the process of setting up Unity Catalog in your Databricks workspace. What is Unity Catalog? Unity Catalog is Databricks’ answer to centralized data governance. It enables organizations to enforce standards-compliant security policies, apply fine-grained access controls, and visualize data lineage across multiple workspaces. It ensures compliance and promotes efficient data management. Key Features: 1] Standards-Compliant Security: ANSI SQL-based access policies that apply across all workspaces in a region. 2] Fine-Grained Access Control: Support for row- and column-level permissions. 3] Audit Logging: Tracks who accessed what data and when. 4] Data Lineage: Provides visualization of data flow and dependencies. Unity Catalog Object Hierarchy Before diving into the setup, it’s important to understand the hierarchical structure of Unity Catalog: 1] Catalogs: The top-level container (e.g., Production, Development) that represents an organizational unit or environment. 2] Schemas: Logical groupings of tables, views, and AI models within a catalog. 3] Tables and Views: These include managed tables fully governed by Unity Catalog and external tables referencing existing cloud storage. Here is the procedure to setup a Unity Catalog Metastore in association with Azure Storage, as I have done for one of our products (SmartPitch Sales & Marketing Agent) – 1] First create a storage account  with primary service being – “Azure Blob Storage or Azure Data Lake Storage Gen 2”; Performance and Redundancy can be chosen based on the requirement for which the DataBricks service is being used.Here for my Mosaic AI Agent, I have used Locally Redundant Storage & Data Lake Gen 2 2] Once the storage account is created, ensure that you have enabled “Hierarchical Namespace” When creating a Unity Catalog metastore with Azure Blob Storage, Hierarchical Namespace (HNS) is required because Unity Catalog needs: a] Folder-like structure to organize catalogs, schemas, and tables. b] Atomic operations (rename, move, delete) on directories and files. c] POSIX-style access controls for fine-grained permissions. d] Faster metadata handling for lineage and governance. HNS turns Azure Blob into ADLS Gen2, which supports these features. 3] Upload any Raw/Unclean files to your metastore folder in the blob storage, which would be required for your use in DataBricks. 4] Create a Unity Catalog Connector in Azure Portal and assign it “Storage Blob Data Contributor” Role . 5] Assign CORS (Cross-Origin Resource Sharing) settings for that storage account. Why this is necessary: In short: Without configuring CORS, Databricks cannot communicate with your storage container to read/write managed tables, schema metadata, or logs. 6] Generate SAS Token   7] Navigate to your Workspace and select “Manage Account” – this should be done from the account admin.  8] Select Catalog tab on the left and then click “Create Metastore”    9] Assign a Name, Region (Same as Workspace), The path to the storage account, and the connector id. 10] Once the Metastore is created, assign it to a workspace .  11] Once this is done, the catalogs and the schemas, and tables in within it can be created. How does Unity Catalog differ from Hive Metastore ? Feature Hive Metastore Unity Catalog Scope Workspace or cluster-specific Centralized, spans multiple workspaces and regions Architecture Single metastore tied to Spark/Hive Cloud-native service integrated with Databricks Object Hierarchy Databases → Tables → Partitions Catalogs → Schemas → Tables/Views/Models Data Assets Supported Tables, views Tables, views, files, ML models, dashboards Security Basic GRANT/DENY at database/table level Fine-grained, ANSI SQL–based (catalog, schema, table, column, row) Lineage Not available Built-in lineage and impact analysis Auditing Limited or external Integrated audit logs across workspaces Storage Management Points to storage locations; no governance Manages external and managed tables with governance Cloud Integration Primarily on cluster storage or external path Secure integration with ADLS Gen2, S3, GCS Permissions Model Spark SQL statements Attribute- and role-based access, unified policies Use Cases Basic metadata store for Spark/Hive workloads Enterprise-wide data governance, sharing, and compliance To conclude, Unity Catalog is the next-generation governance and metadata solution for Databricks, designed to give organizations a single, secure, and scalable way to manage data and AI assets. Unlike the older Hive Metastore, it centralizes control across multiple workspaces, supports fine-grained access policies, delivers built-in lineage and auditing, and integrates seamlessly with cloud storage like Azure Data Lake, S3, or GCS. When setting it up, key steps include: 1] Creating a metastore and linking it to your workspaces. 2] Enabling hierarchical namespace on Azure storage for folder-level security and operations. 3] Configuring CORS to allow Databricks domains to interact with storage. 4] Defining catalogs, schemas, and tables for structured governance. By implementing Unity Catalog, you ensure stronger security, better compliance, and faster data discovery, making your Databricks environment enterprise-ready for analytics and AI. Business Outcomes of Unity Catalog By implementing Unity Catalog, organizations can achieve: Why now? As data volumes and regulatory requirements grow, organizations can no longer rely on fragmented or legacy governance tools. Unity Catalog offers a future-proof foundation for unified data management and AI governance—essential for any modern data-driven enterprise. At CloudFronts, we help enterprises implement and optimize Unity Catalog within Databricks to ensure secure, compliant, and scalable data governance for enterprise data governance.Book a consultation with our experts to explore how Unity Catalog can simplify compliance and boost productivity for your teams.Contact us today at Transform@cloudfronts.com to get started.
