One of the ways to integrate with external systems is using the Extract, Transform, Load (ETL) system. The ETL system creates databases which can be accessed directly by 3rd party tools and solutions. It also allows scheduled execution of transformation scripts on the Data Center Operation server. Together this gives the ability to extract and enter data on the Data Center Operation server.

ETL can be an incredibly complex process, and there are some inherent challenges. Keep these challenges in mind, and how they may affect your business, as you choose an ETL product. Different products take different approaches, but what you select depends on your business requirements and how you use data.

Managing ETL Process

The ETL process seems quite straightforward. As with every application, there is a possibility that the ETL process fails. This can be caused by missing extracts from one of the systems, missing values in one of the reference tables, or simply a connection or power outage. Therefore, it is necessary to design the ETL process keeping fail-recovery in mind.

Who uses ETL?

ETL tools are often visual design tools that allow companies to build the program visually, versus just with programming techniques. For the most part, enterprises and companies that need to build and maintain complex data warehouses will invest in ETL and ETL tools, but other organizations may utilize them on a smaller scale, as well.

Why use ETL?

Since it was first introduced almost 50 years ago, businesses have relied on the ETL process to get a consolidated view of their data. ETL allows organizations to analyze data that resides in multiple locations in a variety of formats, streamlining the reviewing process and driving better business decisions.

Benefits of ETL

  • Transforms data from multiple sources and loads it into various targets
  • Provides deep historical context for businesses
  • Allows organizations to analyze and report on data more efficiently and easily
  • Increases productivity as it quickly moves data without requiring the technical skills of having to code it first
  • Evolves and adapts to changing technology and integration guidelines

Scalability is one of the most important features in a modern ETL tool. The amount of data that businesses collect is only going to continue to grow. You may move data in batches now, but will that always hold true for your business? How many jobs can you run? You need to be able to scale ETL processes and capacity, infinitely if possible. Take advantage of the cloud. When it comes to ETL and data, think big – and fast.

Web Tools


Another big ETL challenge is ensuring that the data you transform is accurate and complete. Manual coding and changes or failure to plan and test before running an ETL job can sometimes introduce errors, including loading duplicates, missing data, and other issues. An ETL tool can reduce the need for hand-coding and help cut down on errors. Data accuracy testing can help spot inconsistencies and duplicates, and monitoring features can help identify instances where you are dealing with incompatible data types and other data management issues.

Web Design


Data is growing in volume. But more importantly, it’s growing in complexity. One enterprise could be handling diverse data from hundreds – or even thousands – of data sources. These can include structured and semi-structured sources, real-time sources, flat files, CSVs, S3 buckets, streaming sources, and whatever new comes along. Some of this data is best transformed in batches, while for others, streaming, continuous data transformation works better. Handling each type of data in the most effective and practical manner can be an enormous challenge.
