In previous article, I mentioned DataGrip vs DBeaver (Comparison) but now in this article, I have mentioned best database comparison tool (free or paid), which a DBA or developer must use to compare schema
Data comparison involves checking for the structural differences between two databases: the source database and the target database. By default, two databases must be compatible for database comparison to be possible. However, you can still compare data using comparison tools when two databases are non-compatible.
So, what are the best and most reliable database comparison tools for developers and DBAs to compare database schemas and propagate schema changes from one environment to another? You will discover them and get detailed information about them in this post.
What Are Data Comparison Tools?
Database comparison tools are database management tools for comparing one database to another. They report similarities and differences between two databases and come in handy during a database updates examination.
Although you can check the differences between two databases manually without using database comparison tools, it takes more time and effort and is less reliable. Therefore, database comparison tools remain the best and the most reliable method. Let’s briefly see how database comparison tools work before discussing the best options you can choose.
How Do Database Comparison Tools Work?
Database comparison tools work by:
- Comparing and synchronizing databases.
- Presenting results after comparison.
- Saving a comparison plan.
- Exporting the results as a report in user-friendly forms like HTML, PDF, Excel, and so on.
