What is a Data Pipeline? Definition, Types and Use Cases

As most companies are moving towards integrating data and analytics into their business operations, the importance of Data Pipelines is increasing at the same pace. But the question is- What is a Data Pipeline? A Data Pipeline is a systematic and automated process for collecting, transforming, and moving data from various sources to a designated destination.  

In other words, a Data Pipeline is the arrangement of network connections and processing that includes transforming data from a source system to a target destination and transforming it for intended business use. Further, read this blog to understand What is a Data Pipeline, how it works, its use cases and more.

Understanding the concept of Data Pipeline  

A Data Pipeline is a series of procedures and tools used to collect, transform and move data from one or more sources to a destination where it can be analysed, stored or utilised for various purposes. Data Pipeline is a fundamental component of Data Engineering, and it is very important for organisations that deal with large volumes of data. The Data Pipeline starts with one or more data sources, which can include databases, files, API sensors, IoT devices and more. These sources generate and store data that needs to be processed.

How does Data Pipeline work?  

Here is the step-by-step overview of how a Data Pipeline works. Let's understand.   

1) Data extraction: The procedure starts with extracting the data from one or more source systems. This involves different methods such as querying a database, reading data from files, fetching data from APIs or gathering data sensors and IoT devices.   

2) Data transformation: Once the data is extracted, it is frequently required to be transformed to make it suitable for the intended use. Data transformation includes tasks like data cleaning, validation, enrichment and aggregation. This process makes sure that data is accurate, consistent and in the desired format.   

3) Data processing: In some cases, Data Pipelines may include data processing steps such as real-time streaming data processing or batch processing for complex computations. This process involves running algorithms, applying Machine Learning models or performing other data operations.   

4) Data loading: After the data is transformed and processed, it is then loaded into a destination system. The destination system is called a data warehouse, data lake, database or any other storage platform where the data will be stored for further analysis.     

5) Data orchestration: Data Pipelines are often complex workflows with many stages and dependencies. The tools and frameworks of data orchestration help in managing the flow of data through the Pipeline. They ensure that every step is in the proper order and can deal with failures and errors with the help of retrying and notifying errors.  

Types of Data Pipeline  

Let’s understand some common types of Data Pipelines:
 

1) ETL Pipeline: ETL stands for Extract, Transform, and Load Pipelines, which are used to extract data from various source systems. It transforms it into a suitable format and then loads it into a target database for analysis.     

2) Real-time Data Pipeline: This type of Data Pipelines process and deliver data as it becomes available, frequently with low-latency requirements. They are used for applications that need immediate insights or actions according to the incoming data.  

3) Batch Data Pipeline: In this Data Pipeline, data is being processed in predefined batches or chunks. These are best for scenarios where data can be processed in the scheduled intervals and does not need any real-time processing. 

4) Data Migration Pipeline: This Data Pipeline is used to transfer data from one system to another during system upgrades, migration or platform changes.      

5) Machine Learning Pipeline: The Machine Learning Pipeline automates the procedure of training, evaluating and deploying Machine Learning models. They enclosed data processing, model training and deployment stages.   

6) Cloud Data Pipeline: This Data Pipeline leverages cloud-based services and resources to process, store and integrate data. They are created to grasp the benefit of the scalability and flexibility of cloud platforms.   

7) Hybrid Data Pipeline: This type of Data Pipeline combines cloud-based and on-premises data processing to meet certain requirements and create a legacy system with modern infrastructure.

Use cases of Data Pipeline  

There are versatile tools in Data Pipelines with a variety of use cases across different industries. Let’s understand.     

1) Business Intelligence and reporting: It is used for extracting data from various data sources, changing it into a certain format and then loading it into a data warehouse to create reports and dashboards. It helps in accurate reporting and making informed decisions.   

2) IoT data processing: It is used to handle huge volumes of data generated by IoT devices for monitoring analysis and automation. It helps in getting real-time insights and keeping predictive maintenance.   

3) Healthcare data processing: It is used in managing and analysing Electronic Health Records (EHRs), patient data and medical imaging for healthcare providers and researchers. It is beneficial in enhancing patient care and medical research advancements.  

4) Machine learning and AI: It is used in creating and maintaining Pipelines for data preparations, model training and evaluation in machine learning and AI applications. It is helpful in automating model updates and real-time predictions.   

5) Financial data processing: It is used in handling financial transactions, market data and risk analysis for banks, trading firms and financial institutions. This helps in risk mitigation and algorithmic trading.
 

Difference between Data Pipeline and ETL Pipeline  

The Data Pipeline and the Extract, Transform and Load (ETL) Pipeline are the same concepts, but there are a few key differences between them. Here are the following differences.    

1) Purpose: A Data Pipeline is a huge concept that includes various data processing workflows, including ETL Pipelines. On the other hand, ETL has a specific purpose of preparing data for analytics and reporting.   

2) Scope: Data Pipelines cover a wide range of data-related workflows, including streaming data, batch processing and more. It does not involve the traditional ETL Process. While ETL pipelines mainly focus on the ETL process, which is about transforming data from source to destination, usually in batch mode.   

3) Data transformation: While the Data Pipeline can include data transformation steps, this transformation can be varied and may not strictly follow the traditional ETL patterns. ETLs are specifically created for data transformation and always follow the structured approach.   

4) Flexibility: When it comes to data processing, Data Pipelines deliver more flexibility and enable organisations to adapt to various data-related situations and use cases. On the other hand, ETL Pipelines are more rigid and mainly focused on the specific ETP procedure, making them less flexible for other types of data processing.   

Conclusion   

So, this is all about Data Pipeline. We hope that you found this blog insightful. In this blog, we have discussed What is a Data Pipeline, how it works, types of Data Pipelines, use cases of Data Pipelines and much more. Organisations can have a lot of Data Pipelines to operate data movements from source systems to target destinations. With thousands of Pipelines, it's important to make it as simple as possible to eradicate management complexity.
