Data pipelines find widespread usage in a range of business use cases. Before we understand why data pipelines are important, let's clear the air around data pipelines first.
Explained simply, a data pipeline is the right combination of digital processing steps to move data from point A to point B. The data is moved from one point to another for storage and/or further data processing, like using it for analytics and combining it with other data.
In a data pipeline, the output of one step serves as the input for the next step. These steps transform and optimize data to a required state per the input requirements of the next destination.
A data pipeline serves multiple use cases for businesses and organizations, offering benefits like:
Data ingestion is a process of pulling data from data sources and feeding it into a pipeline. This is achieved through API calls, webhooks, and replication engines. Data can be ingested into a data pipeline through two approaches:
Batch ingestion: In batch processing, data sets are fed into a pipeline as a group according to a set schedule or a response to an external trigger
Streaming ingestion: In stream processing, data is fed into a pipeline as and when it is generated in real-time
Data ingestion helps businesses collect, import, and process data for storage in a database or for further processing.
Since the entire data pipeline follows a pre-defined process, it ensures that all the collected data is processed and collected consistently. Thus, this ensures that all the information in reports is accurate and consistent.
As data moves through the pipeline from one destination to another, it gets refined and cleaned, proving more meaningful to end users. You won't have to deal with inconsistent date formats, Excel formula errors, copy-and-paste discrepancies, and so on. This boosts your organization's productivity and performance.
A data pipeline automates the repetitive tasks of collecting, transforming, and loading data into different tools and apps. This frees up your time, allowing you to focus on other tasks.
In addition to processing the data, data pipelines also deliver key business insights. The processed data can be fed into the dashboard and reporting tools for effective visualization to make important business decisions.
A data pipeline can boost your marketing campaign by connecting all your data sources (IoT, social media, CRMs, and more) and creating powerful marketing reports. This further ensures that all the marketing data sets are fetched automatically through SaaS APIs for better analysis and educated decision-making.
A data pipeline can streamline e-commerce stores by integrating store data from point-of-sale systems and e-commerce platforms, thus enabling easy inventory management, personalized marketing, and customer segmentation.
A data pipeline helps you make the most out of large volumes of data by converting raw data into high-quality information for business intelligence and analysis.
Not having a data pipeline means manually extracting all the data from different sources. This could work fine if you have to deal with one or two sources. But the whole process will consume a lot of time when you want to collect data from a number of source systems at different times and based on certain external conditions and triggers.
A data pipeline processes raw data, ensuring it is fit for consumption at the next stage. Without a data pipeline, you can still have tons of data, but it would likely be raw, thus prone to errors and mistakes.
There is always a probability of human errors, redundancy, the disparity in data formats, and missing data in the absence of a data pipeline.
Without a data pipeline, data is stored in multiple sources, making way for data silos, data redundancy, and disparity. You can also waste database storage space due to duplicative and redundant data sets.
Enterprises have an exponentially high number of data sources they extract data from. Managing a large number of data sources is tough, especially when you only have a handful number of professionals who do that. What happens if that person leaves? Managing all these sources and documenting the large-scale processes that satisfy different regulators and auditors is tedious and arduous.
Data engineers already have enough on their plates. Without a data pipeline, they will have to invest time in extracting and processing data, thus keeping their hands full.
That said, there are several helpful best practices to consider when establishing a reliable data pipeline.
A data pipeline makes it easier to extract data from multiple data sources. But there is always a lingering question about the whereabouts of data -- who owns them, how were they extracted, or which business process owns it.
While raw data is seldom useful, you might still want to look at it to ensure accuracy. If fed to a data pipeline, inaccurate data will only yield inaccurate results, a scenario you would never want to be in. This is why establishing a data catalog helps. Here is all you need to know about the data catalog.
A cloud-based pipeline enables the communication between different tools and platforms. This way, every entity involved in the process, whether data sources, data lakes, or data warehouses, can communicate among themselves. This will help you save time, effort, and money. Some popular cloud-based warehouses you can use for the process are SnowFlake, Amazon Redshift, and Google BigQuery.
Testing a data processing process for quality ensures there are no bugs in the workflow. This verifies that the processed data is fit for end data consumers.
To ensure that the final data fits end users correctly, data scientists can set up alerts for real-time data errors like column changes, schema, null records, data SLAs, and more.
We know that data ingestion can be achieved through two approaches -- batch and real-time. As data is generated 24 hours daily, periodic or batch data ingestion can miss critical events. Stale data can prove useless and could even have catastrophic consequences, especially when the data is related to the security and safety of the organization.
Thus, using real-time streaming data is highly recommended to never miss any important detail. An even better approach is to have a data pipeline strategy that can handle batch and streaming data.
An effective data integration strategy doesn't stop with a data pipeline. Rather, it starts from here. Once a data pipeline is created, modify and maintain it to ensure it aligns with your requirements.
You can incorporate DataOps or DevOps for data to enable continuous integration, development, and delivery into the pipeline using automation, machine learning, and AI. This will ensure your data is more available, reliable, and consistent.

The terms data pipeline and ETL are often used interchangeably, but they have significant differences (and similarities).
Unlike ELT (Extract, Load, and Transform), ETL, meaning Extract, Transform, Load, is a type of data pipeline where data is extracted from a source, transformed or modified, before being loaded into a final data warehouse, cloud data lake, or other data repository.
Data pipeline is the process of moving data from one point to another. Data could be moved for various purposes -- easy storing, data processing, or combining with other data forms. Unlike ETL, a data pipeline may or may not include data transformation. A data pipeline performs various functions, like:
ETL involves processes to extract data from a source, transform it, and load it into the destination. On the other hand, a data pipeline is a broader concept containing ETL as a subset. A data pipeline, similar to ETL, might involve data transformation and processing, but not always.
ETL, typically runs in batches, meaning that a group or chunk of data is moved at a particular time. Let's say an ETL pipeline runs once every 24 hours. On the other hand, besides supporting batch processing, a data pipeline can also run on real-time data. You can handle incoming and ongoing data flow during data streaming.
In ETL, data is typically loaded into a data warehouse or databank. However, in a data pipeline, the destination could be dictated by your requirements, allowing you to load data to any destination system, including a big data lake or Amazon Web Services bucket, or even trigger the next business processes by activating webhooks.
Both the ETL and data pipelines are similar as these processes involve the movement of data. In a way, ETL is a subset of the data pipeline.
Data engineers and data scientists deal with a huge amount of data from disparate sources on a regular basis. Setting a data pipeline strategy to implement automation to process data saves time, boosts productivity, lets you derive critical insights, and assists you in decision-making.
