Data is prevalent everywhere, which is one of the characteristics of the Information Age. You use data every day to guide your decisions and set goals, whether it’s projected arrival dates for your products or analytics on how much time you spend on your phones. On a bigger scale, organizations use data in the same way. They have information on clients, staff, goods, and services, all of which must be standardized and dispersed throughout diverse groups and systems. Even external partners and vendors may be given access to this information.
What are ETL Tools?
Software called ETL tools is made to enable ETL procedures, which include extracting data from many sources, cleaning it up for consistency and quality, and storing it all together in data warehouses. When used appropriately, ETL technologies offer a consistent approach to data intake, sharing, and storage, which simplifies data management techniques and enhances data quality.
Data-driven platforms and organizations are supported by ETL technologies. The main benefit of customer relationship management (CRM) platforms, for instance, is that all corporate operations may be carried out via a single interface. This makes it possible for teams to readily share CRM data, giving a more complete picture of business performance and goal-setting.
Let’s now look at the four different categories of ETL tools.
Types of ETL Tools
Based on their supporting organization or vendor and infrastructure, ETL tools can be divided into four groups. The following definitions describe the terms “enterprise-grade,” “open-source,” “cloud-based,” and “custom ETL tools.”
1. Enterprise Software ETL Tools
Business software Commercial organizations produce and provide support for ETL tools. Since these businesses were the first to advocate for ETL tools, their solutions tend to be the most reliable and developed in the industry. Offering graphical user interfaces (GUIs) for designing ETL pipelines, support for the majority of relational and non-relational databases, extensive documentation, and user groups are a few examples of what is offered in this regard.
2. Open-Source ETL Tools
It is not surprising that open-source ETL solutions have become available given the growth of the open-source movement. Today, there are several free ETL tools available that provide GUIs for establishing data-sharing processes and observing information flow. Organizations can examine the tool’s infrastructure and expand capabilities by accessing the source code, which is a clear benefit of open-source solutions.
3. Cloud-Based ETL Tools
Cloud service providers (CSPs) increasingly offer ETL tools built on their infrastructure as a result of the broad adoption of cloud and integration platform-as-a-service technologies. Efficiency is a unique benefit of cloud-based ETL technologies. Cloud computing technology offers high availability, elasticity, and latency, allowing computing resources to scale to match the current demands for data processing.
4. Custom ETL Tools
Proprietary ETL tools can be created by businesses with development resources utilizing general programming languages. The ability to create a solution that is specific to the organization’s priorities and processes is the approach’s main benefit. SQL, Python, and Java are common languages used to create ETL solutions. The biggest disadvantage of this strategy is the internal resources needed for testing, maintenance, and updates of a custom ETL tool.
How to Evaluate ETL Tools
Every firm has a distinct business model and culture, and this will be reflected in the data that a company gathers and cherishes. However, there are universal standards that any organization will need to consider while evaluating ETL systems. These standards are listed below.
- Use case: Use case analysis is a crucial factor for ETL technologies. You might not require a solution as robust as large enterprises with complicated datasets if your organization is tiny or if your data analysis needs are modest.
- Budget: Another crucial consideration while assessing ETL software is the pricing. Although open-source tools are often free to use, they might not offer as many features or support as solutions that are designed for businesses. If the product is heavily coded, another factor to take into account is the resources needed to hire and retain developers.
- Capabilities: The finest ETL technologies are adaptable to the data requirements of various teams and business processes. De-duplication is one automated function that ETL technologies can use to enforce data quality and lessen the amount of work needed to examine datasets. Data linkages also make platform sharing more efficient.
- Data sources: Whether data is on-premises or in the cloud, ETL solutions should be able to meet it “where it dwells.” Organizations may also have unstructured data in various formats, as well as complicated data structures. Information from all sources will be able to be extracted by the perfect solution, which will then store in standardized formats.
- Technical literacy: A crucial factor is how well-versed developers and end-users are in data and code. For instance, if the tool needs manual coding, the development team should ideally employ the languages it was created. However, a program that automates this procedure will be excellent if the user is unable to build sophisticated queries.
Next, let’s analyze specific tools for your ETL pipelines and categorize them according to the types mentioned above.
Best ETL Tools
This article has discussed some of the best ETL tools, lets’s have a look at the list given below.
