The best feature is that it can be used for both ETL as well as data access purpose, in one go! It's easy to use because there are no technical skills required to get started with this tool. There could have been better documentation available online which would help people who aren't familiar with SQL query language. I was looking out for an open source solution where we don't need to spend too much money upfront but still got value added features like change management etc. We were able to integrate our existing database system with new ERP application using sqlify. I like that this tool is very user friendly, it has all the features you need for your daily use in a single platform. It's easy to learn how to use. And the customer support is great! There are some things that could be improved such as the number of users we can have at once, but the overall service was good, fast and reliable. We solved problems about data quality and consistency between different databases.
