3. Azure Data Engineering Project Example!
Imagine ‘TechTrend Solutions’ as a streaming company that provides a variety of content, including movies and TV shows, to its subscribers. We have developed a robust data engineering pipeline for TechTrend Solutions to analyze their data and efficiently classify their customers. This solution aims to provide TechTrend Solutions with valuable insights into their customers’ preferences and requirements, ultimately enhancing their understanding of their audience.
Azure Technologies and services we used are
- SQL Server
- Azure Data Factory
- Azure Data Lake Storage (ADLS Gen 2)
- Azure Databricks
- Azure Synapse Analytics.
A. Data Ingestion:
- We had the task of transferring data from an on-premises SQL server to the cloud, specifically ADLS (Azure Data Lake Storage), and we chose to employ Azure Data Factory (ADF) for this purpose.
- Migrating data from an on-premises SQL server to the cloud can be intricate, but we simplified the process by utilizing the Self-Hosted Integration Runtime feature within ADF, providing scalability as needed.
- Using ADF, we efficiently copied all the tables, employing a single copy activity within a “for each” loop. This approach guaranteed that all accessible tables were iterated through and copied to the intended destination.
B. Data Transformations Using Databricks:
- Following data ingestion, we proceeded by creating a Transformed Data container in ADLS (Azure Data Lake Storage) and a corresponding database in Databricks.
- To ensure secure data access, we established a robust connection between the landing container and Databricks. This security was achieved through the use of SAS tokens, a trusted method for accessing files. We implemented this secure connection via the Secret Scope feature.
- Within the Databricks platform, we initiated a series of data transformations, including tasks such as data cleaning, null value removal, outlier handling, and fundamental validation checks.
- In addition to basic transformations, we conducted more advanced data processing to uncover valuable trends and insights within the dataset, aligning with specific business requirements.
- All the data that underwent processing within Databricks was then systematically written back to the Transformed container in ADLS. These processed datasets were also saved in the form of Delta tables for future reference and analysis.
C. Synapse Analytics:
- We employed Azure Synapse Analytics as our central Data Warehouse system.
- With this platform, we could easily execute queries using plain SQL language by creating SQL pools, simplifying data analysis.
- Moreover, Azure Synapse Analytics supported the creation of data pipelines and the execution of Spark applications, all of which could be seamlessly managed through Spark pools or clusters. This allowed us to harness the power of distributed computing for complex data processing tasks.
D. Azure Key Vault:
- To enhance security, we made effective use of Azure Key Vault.
- Azure Key Vault served as a secure storage repository for secret keys, ensuring the confidentiality and integrity of sensitive data throughout the duration of the project.
E. Flow of the Project:
- SQL server data transfer to ADLS initiated the process.
- Subsequent data transformations in Databricks produced Delta tables.
- The processed data was then written back to ADLS.
- Finally, the data was analyzed within Azure Synapse Analytics.
- In essence, our solution facilitated smooth data management and analysis, empowering TechTrend Solutions to provide superior customer service and customize their offerings to align with their customers’ preferences and needs.
4. Data Engineering Certification: Azure Data Engineer Associate DP-203
