Wrapping up
Before selecting any data engineering tools, starting by understanding business needs and designing the data engineering architecture is ideal. As Joe Reis and Matt Housley coined the approach “architecture first and technology second” in Fundamentals of Data Engineering– Architecture design is a must before selecting any tool. Think of architecture as a strategic guide that answers the 3Ws (What, Why, and When) and tools as an implementer of that architecture.
Some other criteria you can use to evaluate the best tools are– is the tool’s UI clean and intuitive? How easy are the tools to learn and master? How long will the tool take to set up? What integrations it offers, and what extensibilities can it support? Lastly, tools should be selected in a way that adds value to your business or data solution while being cost-efficient and future-oriented. Contact our experts to get the best advice on data engineering tools and services tailored to your specific needs.
