What is ETL Developer: Role Description, Process Breakdown, Responsibilities, and Skills
ETL is a type of data integration that refers to the three steps extract, transform, load used to blend data from multiple sources. It's often used to build a data warehouse. During this process, data is taken extracted from a source system, converted transformed into a format that can be analyzed, and stored loaded into a data warehouse or other system. Extract, load, transform ELT is an alternate but related approach designed to push processing down to the database for improved performance.
ETL gained popularity in the s when organizations began using multiple data repositories, or databases, to store different types of business information. The need to integrate data that was spread across these databases grew quickly. ETL became the standard method for taking data from disparate sources and transforming it before loading it to a target source, or destination. In the late s and early s, data warehouses came onto the scene.
A distinct type of database, data warehouses provided integrated access to data from multiple systems — mainframe computers, minicomputers, personal computers and spreadsheets. But different departments often chose different ETL tools to use with different data warehouses. Coupled with mergers and acquisitions, many organizations wound up with several different ETL solutions that were not integrated. Over time, the number of data formats, sources and systems has expanded tremendously.
Extract, transform, load is now just one of several methods organizations use to collect, import and process data. Businesses have relied on the ETL process for many years to get a consolidated view of the data that drives better business decisions. ETL is used to move and transform data from many different sources and load it into various targets, like Hadoop. Data integration has been around for years, but it still plays a vital role in capturing, processing and moving data.

Data integration software from SAS distributes integration tasks across any platform and virtually connects to any source or target data store. Learn more about data integration software from SAS. ETL is a proven method that many organizations rely on every day — such as retailers who need to see sales data regularly, or health care providers looking for an accurate depiction of claims.
ETL is also used to migrate data from legacy systems to modern systems with different data formats. Whoever gets the most data, wins. Today, businesses need access to all sorts of big data — from videos, social media, the Internet of Things IoT , server logs, spatial data, open or crowdsourced data, and more. ETL vendors frequently add new transformations to their tools to support these emerging requirements and new data sources.
Adapters give access to a huge variety of data sources, and data integration tools interact with these adapters to extract and load data efficiently. ETL has evolved to support integration across much more than traditional data warehouses. Advanced ETL tools can load and convert structured and unstructured data into Hadoop. These tools read and write multiple files in parallel from and to Hadoop , simplifying how data is merged into a common transformation process.
Some solutions incorporate libraries of prebuilt ETL transformations for both the transaction and interaction data that run on Hadoop. ETL also supports integration across transactional systems, operational data stores, BI platforms, master data management MDM hubs and the cloud. Self-service data preparation is a fast-growing trend that puts the power of accessing, blending and transforming data into the hands of business users and other nontechnical data professionals.
Ad hoc in nature, this approach increases organizational agility and frees IT from the burden of provisioning data in different formats for business users. Less time is spent on data preparation and more time is spent on generating insights. Consequently, both business and IT data professionals can improve productivity, and organizations can scale up their use of data to make better decisions.
ETL and other data integration software tools — used for data cleansing, profiling and auditing — ensure that data is trustworthy.
ETL tools integrate with data quality tools, and ETL vendors incorporate related tools within their solutions, such as those used for data mapping and data lineage. Metadata helps us understand the lineage of data where it comes from and its impact on other data assets in the organization. With SAS Data Management, you can take advantage of huge volumes of data — for example, customer data from Twitter feeds — to get insights like never before.
Matthew Magne explains how SAS can stream Twitter data into a data lake, cleanse and profile the data, then reveal which customers are most likely to leave. In turn, you can create a plan to retain them. ETL What it is and why it matters.
ETL History ETL gained popularity in the s when organizations began using multiple data repositories, or databases, to store different types of business information. When used with an enterprise data warehouse data at rest , ETL provides deep historical context for the business. By providing a consolidated view, ETL makes it easier for business users to analyze and report on data relevant to their initiatives.
ETL has evolved over time to support emerging integration requirements for things like streaming data. Organizations need both ETL and ELT to bring data together, maintain accuracy and provide the auditing typically required for data warehousing, reporting and analytics. But the historical view afforded by ETL puts data in context.
In turn, organizations get a well-rounded understanding of the business over time. The two approaches need to work together. Benefits of a Single Customer View This energy company stored customer data on different systems and in different formats. Data Integration Reimagined Instead of dying out, old technologies often end up coexisting with new ones.
The most successful organizations will have a clear and precise strategy in place that recognizes data integration as a fundamental cornerstone of their competitive differentiation. Popular uses today include:. ETL and Traditional Uses ETL is a proven method that many organizations rely on every day — such as retailers who need to see sales data regularly, or health care providers looking for an accurate depiction of claims.
ETL and Self-Service Data Access Self-service data preparation is a fast-growing trend that puts the power of accessing, blending and transforming data into the hands of business users and other nontechnical data professionals.
ETL and Data Quality ETL and other data integration software tools — used for data cleansing, profiling and auditing — ensure that data is trustworthy. ETL and Metadata Metadata helps us understand the lineage of data where it comes from and its impact on other data assets in the organization. How It Works ETL is closely related to a number of other data integration functions, processes and techniques. Understanding these provides a clearer view of how ETL works.
SQL Structured query language is the most common method of accessing and transforming data within a database. Transformations, business rules and adapters After extracting data, ETL uses business rules to transform the data into new formats. The transformed data is then loaded into the target. Data mapping Data mapping is part of the transformation process.
Mapping provides detailed instructions to an application about how to get the data it needs to process. It also describes which source field maps to which destination field. For example, the third attribute from a data feed of website activity might be the user name, the fourth might be the time stamp of when that activity happened, and the fifth might be the product that the user clicked on.
An application or ETL process using that data would have to map these same fields or attributes from the source system i. If the destination system was a customer relationship management system, it might store the user name first and the time stamp fifth; it might not store the selected product at all. In this case, a transformation to format the date in the expected format and in the right order , might happen in between the time the data is read from the source and written to the target.
Scripts ETL is a method of automating the scripts set of instructions that run behind the scenes to move and transform data. This resulted in multiple databases running numerous scripts. Early ETL tools ran on mainframes as a batch process.
Organizations today still use both scripts and programmatic data movement methods. Later, organizations added ELT, a complementary method. ELT extracts data from a source system, loads it into a destination system and then uses the processing power of the source system to conduct the transformations. This speeds data processing because it happens where the data lives. Data quality Before data is integrated, a staging area is often created where data can be cleansed, data values can be standardized NC and North Carolina, Mister and Mr.
Many solutions are still standalone, but data quality procedures can now be run as one of the transformations in the data integration process.
Scheduling and processing ETL tools and technologies can provide either batch scheduling or real-time capabilities. They can also process data at high volumes in the server, or they can push down processing to the database level.
This approach of processing in a database as opposed to a specialized engine avoids data duplication and prevents the need to use extra capacity on the database platform. Most banks do a nightly batch process to resolve transactions that occur throughout the day. Web services Web services are an internet-based method of providing data or functionality to various applications in near-real time. This method simplifies data integration processes and can deliver more value from data, faster.
You could create a web service that returns the complete customer profile with a subsecond response time simply by passing a phone number to a web service that extracts the data from multiple sources or an MDM hub. With richer knowledge of the customer, the customer service rep can make better decisions about how to interact with the customer.
Master data management MDM is the process of pulling data together to create a single view of the data across multiple sources. Data virtualization differs from ETL, because even though mapping and joining data still occurs, there is no need for a physical staging table to store the results. Some data virtualization solutions, like SAS Federation Server, provide dynamic data masking, randomization and hashing functions to protect sensitive data from specific roles or groups.
SAS also provides on-demand data quality while the view is generated. Event stream processing and ETL When the speed of data increases to millions of events per second, event stream processing can be used to monitor streams of data, process the data streams and help make more timely decisions.
Senior ETL Data Analyst
The title of this article poses a pertinent question for modern enterprises that increasingly make use of powerful high-end analytic data engines, such as Hadoop clusters and cloud-based data warehouses see this article by Forbes , which deals with similar questions. The challenge for enterprises that use analytic engines is one of data movement—what is the best way to get data from operational systems into data warehouses and other data platforms so that it can be queried for reporting and analytics purposes? ETL Extract, Transform, Load is one such method for moving data, and it is one of the oldest data movement methods. However, debate continues as to how relevant ETL still is.

Any modern company of any significant size around the world has a data science department, and a data engineer at one company might have the same responsibilities as a marketing scientist at another company. Data science jobs are not well-labeled, so make sure to cast a wide net. Of all the roles in the tech world, data scientists probably have the highest variation in titles and job responsibilities. A data scientist has to wear a lot of different hats, and the day-to-day work of a data scientist at Amazon could look significantly different from that of a data scientist at Microsoft. A data scientist is expected to have expert statistical, machine learning, and often economical skills and knowledge.
