What is Data Engineering?

Data Engineering is a robust process of handling your data. It means designing, building, and managing the entire infrastructure of your business. This enables organizations to store, process, and analyze huge amounts of data. Data engineers can then build pipelines. These pipelines can transform raw data from different sources into clean and structured datasets. These can be used by data scientists and analysts to gain value-added insights.

Core Components of Data Engineering

Data engineering is a critical process that includes collecting, transforming, and optimizing raw data into useful formats. There are various tools and technologies available in the market. But its core components remain the same. And they are the pillar of any successful data engineering strategy. The core components of Data Engineering include:

Data Collection
Data collection is at the center of any data engineering system. This means collecting data from various sources, be it internal or external data. It may include different data sources like APIs, databases, social media platforms, sensors, log files, APIs, and 3^rd party providers.

It is difficult to collect data from various different sources. You can get data in unstructured format like raw text or JSON files. You can also receive data from structured formats like SQL databases. Data engineers must make sure that all the important and relevant data is collected.

Key Technologies

Database Management Systems (DBMS): MySQL, PostgreSQL, and Microsoft SQL Server.
API Integration: RESTful services, webhooks, and third-party API connectors.
Message Queues: Apache Kafka and RabbitMQ. They help to capture real-time data streams from sensors and apps.

Data Ingestion
After the data is collected, it must be ingested into a central system to process it. It includes processing data into a data platform or storage system that can seamlessly manage structured and unstructured data. Data can be processed in two ways:

Batch Processing: In this way, a large amount of data is collected and ingested at certain intervals hourly or daily.
Real-Time or Streaming: In this way, the data is ingested the moment it becomes available. Hence, it allows real-time insights and analytics.

From the two mentioned above, batch ingestion is most common for enterprises who don’t have urgency of their data. But, for customer engagement and fraud detection purposes, real-time ingestion is important.

Key Technologies

Batch Processing: Apache Sqoop, Azure Data Factory.
Real-Time Processing: Apache Kafka, Azure Stream Analytics, Amazon Kinesis.

Data Storage
After the data is ingested, it should be stored in a system that is able to handle huge amounts of data. This data must be accessible for further analysis. Data engineers choose storage solutions based on volume, variety, and analysis. Three main types of storage systems include: Three main types of storage systems include:

Relational Databases: With the help of DQL databases, structured data is stored in a predefined schema. It is the best for transactional data.
Data Lakes: Here, massive volumes of semi-structured and unstructured data are stored. Data lakes are best for storing raw data, which can be refined later on.
Data Warehouses: These are highly structured storage systems. It contains all the processes and curated data. They are optimized for query performance and accurate reporting.

Key Technologies

Relational Databases: Microsoft SQL Server, MySQL, PostgreSQL.
Data Lakes: Azure Data Lake, AWS S3.
Data Warehouses: Snowflake, Google Big Query, Azure Synapse Analytics.

Data Processing and Transformation
Raw data cannot be used for analysis. Data engineers must process and transform this data to get proper insights. It consists of tasks like data filtering, joining, cleansing, and aggregating. So, this is where you need Extract, Transform, Load (ETL) or Extract, Load, Transform (ELT) pipelines. These pipelines help to extract data from the source systems and transform it as per business logic. Then, it is loaded into the storage system for further analysis.

Key Technologies

ETL Tools: Talend, Apache NiFi, Azure Data Factory.
Distributed Processing: Apache Spark, Hadoop, Databricks.

Data Pipeline Automation
Data pipelines have automated workflows that integrate various different stages of data processing. This includes data from ingestion to transformation to storage. After that, automation is required to ensure that these pipelines run without the need of any manual intervention. This is beneficial, especially in situations when you need to ingest and process data in real time.

A robust data pipeline will reduce downtime and eradicate errors. This empowers organizations to manage continuous data flow with zero or minimum disruption.

Key Technologies

Orchestration Tools: Apache Airflow, Azure Data Factory, Prefect.
CI/CD for Data: Jenkins, GitLab CI/CD integrated with data pipeline tools.

Data Security
Today, data privacy laws like GDPR and CCPA have become more strict. Hence, data security is the most important for your organization. Data engineers must ensure that a company’s sensitive data is protected throughout its entire lifecycle. Data engineers must include robust security measures in all the data-related processes like collection or storage, etc. Some of the key security practices include Data Encryption, Access Control (RBAC and IAM), and Data Masking and Anonymization (PII).

Key Technologies

Encryption Tools: Azure Key Vault, AWS KMS, OpenSSL.
Access Control: Azure Active Directory, AWS IAM.
Data Masking Tools: IBM InfoSphere Optim, Informatica Data Masking.

How to Build a Robust Data Pipeline with Azure?

If you want to know the power of Azure Data Engineering, have a look at this guide. Below are some simple steps to building a cutting-edge data pipeline with the help of Azure services

Step 1: Data Ingestion
The first step is to collect data from various sources. With the help of Azure Data Factory, enterprises can connect to cloud sources, on-premises databases, and 3^rd party APIs.

For instance, a retail enterprise can collect data from different systems like ERP, CRM, and their eCommerce website.

Step 2: Data Storage
After ingesting the data, it is stored in Azure Data Lake Storage or Azure Blob Storage. It is a scalable storage solution that enables you to store structured and unstructured data.

For instance, the retail company can store both – Transactional data from sales, inventory, etc. And customer data like purchase history, preferences, etc., in the lake.

Step 3: Data Transformation
After the data is stored, the third is to clean, transform, and prepare that data for further analysis. For this step, Azure Databricks is the best platform. It enables real-time data processing and advanced transformation with the help of Apache Spark.

For instance, the retail company can then transform sales data. This can be done by cleaning invalid entries. You can aggregate metrics by region. You can also calculate customer lifetime value.

Step 4: Data Analytics and Reporting
Then, this transformed data is moved to Azure Synapse Analytics. Azure Synapse enables organizations to run complex queries. It also helps to build ML models and create reports with the help of Power BI.

For instance, the retail company can create dashboards to keep an eye on regional sales performance. They can also monitor customer behavior trends, real-time inventory levels, and much more.

Step 5: Data Security and Compliance
The last and most important step is to ensure that your data engineers use Azure’s built-in security features throughout the process. The features like access control, encryption, and network security can help to protect sensitive business information.
